96-99 Gmc 350 for third gen??

ok so i found one at a local junk yard
it might have a bad head gasket or maybe a crack in the head
if there is he will switch heads but my question is
what do exactly do i need off of it ? short block, heads,vavle covers, distributor , umm anything im gunna need , oh yea this is going in a 87 camaro z28 that currently has a 305 carb , umm im staying with the carb setup i know i got buy a new intake manafold to match the differnt bolt patterns, umm oh yea he didnt really say the year of it but it looks like its with in 96-99 i pulled the vavle cover and checked the casting its the 906 vortec heads
will i have to mess with the wiring harness or the ECU
bellhousing and flywheel will line right up? umm
basicly tryin to find out as much as possible


*edit* hrmm...... maybe ill go back and check out some other ones he had maybe i can find some 062's =\ :banghead:

If the heads are bad see if he'll replace them with the good heads. As far as what you'll need, I'd take it all. I'm sure the bell houseing will match up. You shouldn't have to use the wiring harness since you are staying with the carb, and I don't believe you can use the distributor but I could be wrong.

what are the major differnces in the two casting 906 and 062 just the hardened exhaust seat?
what does that mean i cant port that part?

ok the heads are cause for concern, even if they are ok, hit em with a hammer till it cracks and get a set of 062's. the 906 and 062 are different exhaust seats, that cant be ported, but also the 906 have different exhaust ports that dont flow as well, which does a shitty job of evacuating the cylnder on the exhaust stroke. if you are stuck with the 906 castings, get a set of manley street flow valves, that have undercut stems near the valve face, which they claim can increase flow by up to 40%, which would help the heads, they do have the LT1 170cc intake port, so you can still get decent performance from them, so if youre just lookin for a mild street 350, makin around 350hp, they will work, but if you ever wanna go more, youre gonna need to upgrade them to at least the 062 castings.

as far as what youll need. if your gonna keep the carburated setup, then all you need is the block, and the rotating assembly inside it, and the heads. perhaps the oil pan, but you might need the oil pan from the original engine to clear the front crossmember. leave everything else behind. just buy the new TBI/Vortec intake, and bolt it all together. its a no brainer. might i suggest that you tear down and rebuild the 350 with new bearings and piston rings however, just what i would do with a junkyard engine. the stock pisonts are also pretty shitty, so while you got it appart, i might also sugget a new set of forged aftermarket slugs. set up for the propor compression for street engines.

Stupid question, but what did the engine cost ya?? Just curious.

well ive looked for a while around here and the best price ive goten was 325 with the distributor ,heads , short block and if a head is bad he'll replace it
oh and i go there tomorrow to put some money down on it im gunna start pullin vavle covers to the other vortecs he has and try to find some 062's ill only keep the 906's if i have no other choice
i know he has one that came out of a tahoe but it looked burnt pretty bad so im not sure about that one but ill look

if i have to keep the 906's what would be teh best setup?
2.02in/1.6ex vavles?
springs ?

well if you run the 906 heads, you have to keep the 1.5in exhaust valve, as far as the intake i would think you can machine it out to 2.02 but you might over stuff the cylender with that limited exhaust valve, at the very best youd have to run a dual pattern camshaft favoring the exhaust side. or run the standard valve on the intake, and use the street flow valve on the exhaust to try and even them out a bit. for springs it depends on what kinda lift your looking at, but comp cams makes a behive spring that i recomend for street engines running vortec heads. but id run it past their cam help line to see if those springs will work with the cam you pick. but if you wind up wanting to run regular springs youll have to machine the spring seat, cut down the valve guide to make it both shorter and smaller in outside diameter to clear dual spring setups. and allow more lift.

Man, shit's expencive up there. I can go and get a complet long block for 50 bones and a turn key for 125. Gotta love the "U" pull it places.

man everything in CA, LA is expensive man its like almost 1000 bucks for some shity ass dirty apartments in BAD neiborhoods

yea the cost of living in cali is alot higher

does anybody know exactly what year and model had the 062's i remember seeing it somewhere but cant find it any more

jus go here.... thats where i got it

i would start with 99 chevy tahoes, suburbans, silverados, and GMC equivilants, and go backwards till 96. newer the better. less wear and tare and any unlisted improovmants they might have made. my 062 castings came off a 99 chevy tahoe. avoid box vans and other G vans as they usually have the 906 castings.

well these were already pulled there were just on the floor , there was like a 99 tahoe that just came out but im not sure about it cause it was in a fire, a short in the alarm or some bullshit but i dont know if i can trust it, havnt pulled the vavle covers on it

yeah thats a sketchy one, depends on how bad the fire was i suppose, if the guys willing to work with ya, take the heads off that one to a machine shop and have em check em out. if they are ok, not warped or anything, keep em, they should be fine, if they dont check out ok, exchange em like the guy said you could with the 906 castings.

are the vortec heads known for cracks? i think somebody said that somewhere dont remember where tho

never heard of that before. im a gm tech, and certainly never seen one in for that before. they have typical gm intake leaks, but not very common, not like the V6 engines. the engine i got had a coolant leak, but all that happend was the lifters collapsed and the bearings died. but the rest was solid.

aye would you happen to know the cost of the #062's i got a friend that works for chevy hes gunna find out but i was just currious , i might have him just buy me a new set
i think its like cost plus 10%

should be around 525.oo for a pair, regular cost. i dont know if employee discount applies to things like heads and engines.

ive seen then for 425 brand new in teh box

yeah i remember they were that price a while ago, but from what ive seen the complete sets have gone up in price, but hey man, if you find em cheaper, run with it :)
