hi im doing a lt1 head and intake swap to my l98 and i was thinking of change the cam the same time. my first options is a stock lt1 cam or a cc 07-503-12
XR276HR-12 . the reason is that those cams laying around .
I run a stock converter and a 2,73. does it work at all?
if I go 503 what else do I need ilke springs and so on?

spec.
l98 short block
lt1 intake w 24lb inj.
lt1 heads
shorties headers
any thing else I sould consider?
excuse my english Im from Sweden

A few questions...

Are they aluminum or iron LT1 heads?

Who is doing the welding and machining to make them (heads and intake) fit the 1st gen block?

Are you ok with not running the 1st gen accesories?

ANd lastly why dont you just do the whole LT1 swap? With the machining done to the LT1 intake you can even run a stock TPI harness and distributor.

Alu heads. well LT1's just dont laying around in junkyards over here and I've got the intake and heads pretty cheap.
The welding and machining is done at my work for coffee bread

1st gen accesories is what Im planing to use. is that a problem?

Unless you want to fit it with better gears and a stall converter the stock LT1 cam is your best option.

A 95-up Vortec V-6 S-10 Blazer stall converter will stall out at 2400 rpm and with the LT1 cam is just about perfect.

A set of 3.42 gears are a great improvement from the 2.73's and still cruise at a fairly low RPM.

Well accesory brackets bolt to the heads in the 3rd gen cars and I believe the lT1 bolt holes are spaced differently.

I dont know of they can be drilled for gen1 style brackets but it's something to look into.

I just thought that clearance issue with cooling line would be the problem.
hope anyone can answer if it's doable
