302 motor

i have a motor with the block of 3932388. i have been told that its a 327, a 350, and a 302 from years ranging to 1964-1969. if anyone could give me a definate answer, then i would appreciate it greatly. thanx

i highly doubt it's a 302. that is an EXTREMELY rare motor found only in late 60s Rally Sport Camaros. I'm not positive, but I'd bet my money that it wasn't a 302. What you could do is call a dealership and ask how you could check that casting number, they should be able to help.

Weren't there 302's in Z28's?

I took this info from chevy-camaro.com

Hope it helps you out.

Q. Rarity of SBC blocks with casting #3932388.

A. This seems to be a popular question lately. The casting number 3932388 is rare because not many cars much less Camaro's got this block casting number that are known. The book Chevrolet By the Numbers 1965-69 says this engine was put in 1969 passenger cars and Camaro's. Their notes say this:
"Very little is known about this block. It seems that most blocks were Tonawanda cast and built, but some Norwood assembled Z28's used this block with Flint-produced engines. From all indications the block is identical to #3932386. It has been found in Passenger cars with the 350/300hp engine suffix code stamping. At least four SS 350 and at least two Z28 Camaros were built with this block, with casting dates ranging from L 20 8 to C 11 9. At least one Camaro was built it September 1969 with this block. Other cars could have received this rare block, but it is unknown which or why. Most #3932388 blocks are dated from September to December 1968." We have apparently had all Camaro owners (according to Chevrolet By the Numbers 1965-69) of this block casting number to email us about it though. The problem is there are no exact numbers as to how many cars had this block casting number. The block doesn't have any special features that sets it off from the rest that would make it any more desirable than other blocks from that time period though.

According to this site it is a 350 from 69. Came with either 2 or 4 bolt main caps.

Weren't there 302's in Z28's?

Yep, specifically from the 1969 Z28; named the DZ302. They're bad assed.

yeah they are, and thank god yall know that, im putting a 302 in my third gen, and puttin the 302 badges on teh hood, and everyone keeps asking why im putting a ford engine in my camaro. and i have to tell them chevy had it a good 20-25 years earlyer. the 69 302 was a firecracker, rated at 290 hp, but really made around 390. and no one makes small small blocks anymore, im lost as to why.

the 302 made no where near 390, at the most, 350 hp. or at least that what the one that one of the st. racers has been dynoed at

If youve got dyno sheets, ill go with your statement, i just remember reading that hp rating in a camaro book once. but i dont think there was a dyno sheet to proove it. thanx for the correction. :)

lol, the dyno sheets would be like the holy grail, the duds an ass hole:-D, and sown three people, me, since i was there to dyno my old car,, and two people in his club, i will see what i can do

dont worry bout it, i always thought that near 400 hp was pretty high for the tech back in the day, heads were crap, and carbs were, well, not quite perfect. so 340-350 sounds better to me anyway, didnt mean to send you on a mission or anything. lol

thats cool man, its not he would have let them out of his sight, its with the build sheet, and the protect"o" plate, but hey, has anyone ever seen the stricking similarity between Speed Racer, and Jeff Gordon, think about it, its kinda erire, and would a 402Big BLock fit in a 3rd gen?

hmm, speed racer, and jeff gordon, never really thought about it. as far as the big block, thats a perty popular question on here, and im pretty sure it can be done, ive seen it in the mags, but i dont know where to get the conversion kits, or if you have to fab everythign yourself, but physicaly, it will all fit. but you have to rerout everything, and basicly re-engineer the whole underhood of the car so it all works. so in my opinion, unless you buy it that way, or have LOADS of money and know how, its more of a pain than its worth, better to build a stroker small block if you want the cubes. im looking at using a 400 block to make a 427 small block to put in my IROC. from the outside, just look like a TPI 350. could even say it was a 305 ;) can we say sleeper :) well, untill i started it anyway. "honest, its just the exhaust" :-D although, id have to fight really hard not to put those ZL1 or 427 badtges on the fenders :)

, lo, i have a 305TPI in mine(ours, me and the girl friend)but i have a 3 inch all th way back, and i am already getting the whole is that a stroker in that, its great tho when the little civics that ask that, then want to race me even more because cause it "only" a 305 and then i hand them there ass, lol, iroc 3 imports 0, not to bad for a 305 that is popping out of the intake, damn the HEI ingetion, lol. any ideas on that one, it only does the popping out of the intake from 2300-3200, so it gets kinda of annyoing around town.

News flash for all you 302 guys who dont know much, 290 horses, but it actually revved up to (or over) 8000 RPM's and when you let the clutch out a bit you could squeek the tires, blub blub blub squeeeeeek blub blub blub squeeeeek

hey macho, read up a little farther, already said they were rated at 290, that was back when they downrated stuff to drop insurance rates, kidna like the ZL1 was rated at 425 hp, actualy made more than 500. we were talkin actual horsepower, but thanks for speaken up ;) as far as your problem boots, i would say its definately somewhere between the coil and the plugs, either a burned wire, a HEI control module, cap, rotors, coil, maybe even some screwed up plugs, or the timing. when was your last tune up? should have included all that but the module.

also boots, have you run the codes on the car yet, more likeley than not the computer will tell you whats wrong, or at least give you a point in the right direction. you can run the codes yourself with a paperclip, id be happy to tell you how if you dont already know. its pretty easy.

we already fixed, lol, we have had this car since wensday,and i took it to a friend of mine to do all the stuff that iwas to lazy to do. plugs/wires/filters/timing, and found out somthing, hey, you have crossed wires, so its all fixed now, but then on saterday, the 700r4 said fuck you, and went out, lol, so ya, that car is parked for winter anyways, since we had our first snowfall here in iowa, but if anyone has a cheep 700r4 lying around, please tell me

lol, isnt that always the way ;) soon as i had a buddy at work start on my B&M 700R4 for the IROC, the one in there blows its three four clutchpack, i have first, second and neutral :)

A 302 was a 327 block w/ a 282 crank w;/a 30-30 cam double hump heads w/ factory screw in studs 202 vavles 64cc closed chamber heads and accesory bolt holes, an alluminum high rise intake that a holley carb bolted on directly. So therefore there were no 302 blocks according to everything I have read or have found out.

As far as I know, the 302 was built for competition in the trans am series. They couldn't have more than 5 liters. So, GM used off the shelf parts and put together the 302. I know of a guy that built one and tried to use it with a powerglide tranny. He said it sucked ass in his '69. My other friend suggested using a manual tranny with it instead. He changed it over and has had a blast with it ever since.
He also hates it when people ask him why he's running a Ford engine :rolleyes:

bc8098 - technicly you are correct, there were no 302 specific blocks, nore were there any 327, or 350 specific blocks. they were all small blocks with a 4in bore. the difference was the build dates, and production stamps. engines built in a certain break point on the id numbers are known to have certain peices, such as the stroke of the crank, heads, and cam. so when someone talks about a 302 block, it is a 4in bore small block, built within the break points known to have originally been a 302 from the factory.

burnM - exactly right, trans am raing had a cid limit of 305cid. so a very smart guy at gm threw a 283 crank in the 327 block to get 302cid. but you do have to rev them before they really come alive. a magazine i read said they were kinda weak at lower rpms, but once you wound em up, they compaired the pull to a hemi. probly why the manual made the engine more fun to drive.

i see no resemblance between speed race and gordon. for one thing speed racer was a good driver...haha... DEI ROCKS DAYTONA!!!

Ok guys here goes. First off, the 327 did have it's own specific block, it is known as the small journal 4 inch bore. up until late 68, when it was replaced with a more common 350 (larger journal) main bore. What does that mean? It means that you physically cannot take a 350 block and make a 302. It also means that you cannot take late 327 blocks and make a 302. All 302 blocks had the smaller 283 journal, (try finding a 283 crank nowadays)! Check your numbers! I believe 302 blocks may have a "DZ" stamped by the casting number but not sure, if someone knows anything about this, reply. This I do know, you can't run an automatic with a 302, it won't work. All DZ302 motors had muncie's behind them, for a reason. Don't try it, it won't work. All DZ302 motors were also 4-bolt. Yes they did rev up past 8 thousand RPM's. Check out Dave Strickler's "Old Reliable". The car still makes appearances know and then, look for it on the web. I had the opportunity to ride in a real 69 Z28 many years ago and man, there is nothing like the sound of a solid lifter small block at 8 grand! That you just can't explain it unless you have experienced it for yourself. I guess that is why people pay 40k plus for these cars nowadays, it's performance that stays with you in a BIG way. The way them old cars rattle at high speeds, the rawness of it, just can't be experienced in today's modern cars.

Listen pal, you obviously have no clue of what you are talking about. The chevy 302 was built in 67,68,and 69. The 67 was a small Journal 2657 Block that was also used for the 327. 68 and 69 302's were Large Journal. You can put a 283 sm Journal crank in a large Journal 350 Block if you want to build a home made version of a 302. All you need are special bearings from TRW part # MS3110P. Do your homework before you go running your Jaws about something you have no clue about. We are supposed to help people on here......not feed them full of crap to try to make ourselves think we know what we are talking about !!!!!

Look at the date in the left corner of the post. The last post was in 2004. I am sure the person your talking to is no longer here. Try not to bring threads back that are more than a month or two old.

Thanks
