lt1 cam in an olds 350 rocket?
lt1 cam in an olds 350 rocket? I have the stock cam for my 97 TA and at this time we are putting a rebuilt motor in my buddies 68 Cutless. Will the lt1 cam work in the car and make more power than a standard ground cam? He says no I want to ask cause he is assuming no. I tried to join the lt1tech and had no luck joining or contacting anyone so if someone here knows help me out...
TIA.
TIA.
olds 350 are not big blocks, they are small blocks, but they are VERY different then chevys. nothing interchanges.
oh and FYI, Olds, Buick, and Pontiac had their own 455's. all different in every way. same with the 350's, but Pontiac NEVER made a small block or big block. they were ALL one size on the outside. from 326-455. almost everthing interchanges. thought i'd through that in, in case you find yourselves chatting with some GM muscle car guys.

Well I just did some reasearch. I was under the impression that Olds used one block size: Big, but apparently they did have SB and BB motors. Here's how to tell the difference. (For those who care)
-A small block measures 12" between the heads at the manifold base.
-A big block measures 14" between the heads at the manifold base.
-Facing the front of the engine, at the top surface of the timing chain area, to the left of the oil fill tube, there is a code about 1.5" high followed by the casting number. A letter indicates a big block, a number indicates a small block.
- Big blocks have a little hump in that area, whereas the small blocks have a completely flat shelf.
- Small blocks from 1977 onward will have the CID or liters cast in large numbers right above the center core plug. The engine VIN number will also be cast onto the side of the block.
SB motors are the: 260, 307, 330, 350 403 and 350 Diesel
BB motors are the: 400, 425 and 455
Also, "All Olds V-8 pushrod engines produced between 1949 and 1990 are considered "Rocket" engines. The "Rocket" designation comes from the general design of these engines."

The 455s did have a slightly different block different crank journal sizes, but the blocks overall dimensions are the same.
Plus the pontiac 455 uses the same cam as a pontiac 326 as well as all the others, except the pontiac step child the 301

I would've said the stepchild was the 307, misbehaving, being complicated etc lol
You should let 442.com know that Cappy, see what they think. I always have, and probably always will, consider BOP to be big blocks, since they are A) BIG B) Bigger than GM, Ford, Chrysler small blocks.

Well the Small Block vs. Big Block thing spills over from Chevys Fords and Chryslers many people think it refers to whether the cubes are big or small, but its like a Chevy 400, its a small block, but a Chevy 396 is a big block, yes it does boggle the mind doesnt it.
but since the Pontiacs, Buicks and Olds V-8s use basically the same block, therefore you cant correctly apply a Small Block or Big Block tag to them.
Oh and you havent heard of the Pontiac 301?? it was used in 80-82 those engines SUCK! nobody makes anything performance wise for them.
and the 301 is the only Pontiac V-8 that has virtually no interchangablity with the other Ponchos

Oh I've heard of the 301 lol It was turbo'd in 81 because it sucked that much lol But the 307 has problems so much. And I never thought of the Pont 350 as a smallblock, but a big block. I never would've considered anything BOP, regaurdless of cube size, to be a small block, since it's the same block.
Wow lots of good info. I managed to start a thread that ended with some meaning. I wanted to ask though. No point in assuming no.
On another note i spent 6 hours changing plugs last night and still have 4,6,8 left. I got 4 out but man trouble getting it in. #2 was a beast. I spent 2 hours working on it and finally got lucky and was able to thread it. N By the way my wrist is 9.75" around. So there are no skinny fingers here. Definitly hardest plug change I have ever incountered. I have had no luck with using vacume tube on the plug either. Worked like a charm on my Typhoon.

hey, a '67 400 head. HO even. just so everyone else knows, Buick, Olds and Pontiac are there own engines. nothing between them interchange. the only thing they have in common are the trans bolt pattern.
I was already fully aware of them being different.
