Cam Choice
Just wondering what the preferred roller cam choice would be for my TTA that is going to have the following upgrades:
4.1 liter "291" block. 8.0 to 1 J&E pistons with "515" heads probably between 8.5 to 8.7 to one ultimate compression ratio. Larger stainless steel valves in ported "515" heads. All the other mods are included in my signiture I would like to run low elevens to high ten on relatively low boost levels (18 to 20 PSI) and have a smooth idle too. Am I asking for alot?

I ended up with a 210/210 roller cam.
I would say that or a 212/212. later Jeremy

Which brand of cam did you go with? How is your idle quality on your 210/210?

My roller cam stuff is all Comp.
Idle with a good tune is almost no different than stock. Running a PT-67, Champion CNC heads and intake, etc and so forth and more etc. lol Had same goals as you, I want to get 10's on pump gas when I get it dialed in and my tranny issue resolved. later Jeremy

Hey Gary:
Who's going to tune your car for you and what fuel management set up are you running? Jason
