350

will a 350ci engine fit(wiring and all) in my 94 z28? it currently has a v6. and up to what size will an engine fit in my car?

thanks,
Alec

Well, for one, if you have a Z28, then you should already have a V8 LT1 that's a 350. If it is a V6, then it's not a Z28.

Secondly, if you do have a 94 V6, then an LT1 shouldn't have a problem bolting in there. It's technically a 346, but that's neither here nor there...

I read the lt1 was a 350ci & the ls1 was a 346ci though I read that on some import forum so it was probably wrong.

They're both 5.7L motors, which equal 346 cubic inches...

thanks for the reply. one more question, does it have to be an lt1 in order to fit in the camaro, or can I just buy a 350 small block chevy(i want more horsepower than what lt1 has to offer) and install it without having to do any serious rearranging? thanks again

Well, the V8's that bolt right into a 94 Z are going to be LT1-derived powerhouses. An LT1 383 would be one that started as an LT1 350 and was bored over to get 383 cubes. I think that's how it works...

When comparing a stock pre-LT1 350 vs a LT1 350, the LT1 has more horsepower (and reliablity). But if you are wanting to modify either enige, the LT1 will cost you more on some of the parts (intake, heads, fuel system).

i dont think u understood my question. i meant to ask if a non-LT engine would bolt up to it. like a 350 smallblock or something. and what's so good about the lt1 engine? its only like 275-305hp no?

i've seen some LT1s on ebay going for pretty low prices(below $1000), Lt1 has more horsepower than any other 350? i saw a 350 with 557hp crate engine for $3500... then again im a newbie so i dont know much about this stuff but feel free to tell me about it.. or just flame me : ))

The difference in a 350 LT1 and a reg. 350 is the LT1 comes factory stock w/ 275-305 hp but it will last longer because it has a 4340 steel crank and special lite weight pistons. If you rubuild an LT1 and put just any piston they will be too heavy and to big. Yes a reg 350 will bolt up to your car( same block bolt pattern). Also A 383 is bored over but it has a 400 cubic inch crank in a 350 block. the crank length is the same as the 350 but the stroke is different. It produces alot of low end tourqe as well as top end power. good luck

They're both 5.7L motors, which equal 346 cubic inches...

No, they are NOT both 5.7L motors. The LS1 is 3.90" bore and 3.622" stroke, which equals out to 346.14 cubic inches, or 5.672 litres. The LT1 uses a 4" bore and 3.48" stroke, working out to 349.85 cubic inches, or 5.733 litres. 5.7 litres rounds out to 348 cubic inches, not 346. Neither motor is truely 5.7 litres, it's rounding on both parts.

If you look at the sales sticker on an LS1 camaro or trans am, does it not say "5.7L V8"???? Ive never heard it advertised as a 5.6L. Besides if you round off what amount it is in litres, it gets rounded upto 5.7L. They are both 5.7L engines, just different blocks and the displacement is a little off.

As far as fitting an older 350 into your 94, they should all fit no problem. You may need different motor mounts but I dont see any reason why you couldnt stuff one in there because they arent really any different in overall size.

liters cant be acuratly comparted to CI really. proving my point, how is a 302, 305, and a 307 all 5.0 liters. it is all just rounded.

and just asking to maybe give unforgiven something else to think about, but, will he have to swap his trany out too or is the bell housing the same patern?

Ok, he is right, a 350 smallblock is 350ci in dispacement, an Lt1 is 350 inches in displacement, but an LS1 in 346 in displacement, as yes, it is a totally different engine so the bore and stroke are completely different. And a 383 is a Stroked 350 not bored.

383 is bored AND stroked 350 :P

mines 40 over

Well your pushing the limits there ridge. I think you can go upto 60 or soemthing sometimes but I wouldnt go any bigger than 30 over. Atleast then I should be able to get one rebuild out of the block.

I'm not trying to be a dick, but a 383 is a stroked 350, no boring... you buy a STROKER KIT which lengthens the stroke, changing the diplacement of the engine from 350ci to 383ci... if you buy the kit w/ more than just the rods and stuff you need for stroking, it may also change the compress w/ new heads, etc... but it is all about changing the stroke, not the bore.

umm your right your not trying to be a dick yet you are. its a 400 crank in a 350 and you have to bore it out 30 over, then you get 383CI. run the numbers smart one.

A 383 isnt just a stroked 350. 350 has a 4" bore. That with the usual 3.75" stroke only gives you 376.99 cubic inches.

Once you bore it 30 over the cubic inches increases to 382.67.... 383 cubic inches.

yea well the block was already 30 over and honeing wouldnt get all the ridges and such out so we had no choice except to go 40 over

and yes 60 over is the farthest you can go cause the motor in have in my car now is 60 over

yeah, unless its some aftermarket block anyway. and you can go 60 over without a problem as long as the work is quality usualy. unless your using some really long stroke that puts alot of load on the side of the walls you are fine. my 350 is 60 over with no problems.
