LT1 camshaft suggestions?

[Lynn]

Back to the OP. Cheapest way to go would be the Elgin cam. ELGE904PMDL

Virtually identical to the LT-1 camshaft.

You are going to be right on the edge of detonation.

If you are planning to disassemble the short block anyway, and you want to have a little hedge against detonation, you could have .010 cut off the tops of the pistons. Would actually help turbulence a bit. You would want to have the rotating assy balanced, but I do that on every engine build. Cheap insurance.

If you are wanting to go roller, call Chris Straub at Straub technologies. He is on the cutting edge of camshaft technology for old school SBC engines.

no harm guys were all motorheads! thanks Lynn I was thinking going back to stock solid lifter cam but another I would consider are the off road cams #140 and #754 ? or stay with LT1? I'm not milling pistons staying stock. again I want this drivable on what's available at the pump

Then you reference two cams that are very lumpy and long on duration?

3927140 Mechanical - 257/269 - .493/.512 - 112 - Off Road
3965754 Mechanical - 262/273 - .488/.509 - 112 - 2nd Design

I'm thinking you should maybe touch base with Comp Cams tech support. They can help you select something that will work better for your needs.

Graeme I didn't ask for a lumpy idle, but you recommended several lumpy cams for that guy
I did ask about the off-road cams, not because they are lumpy. IIRC I started the thread with questions am I not allowed to ask others? with my LT1 I have a blank canvas and I ask because I am not a cam expert I don't want do this over because I grabbed what sounded cool so please give a guy with little experience a break would you?
