I need a turbo cam for a 4.00"x3.48" LT1 with stock castings, no port or chamber work. I would use the stock cam, but I don't have one anymore. I figure, I might as well just buy one. This is not a dyno queen or record breaker but, indeed, a fun, twin-turbo street/track car so I would like to keep the lift moderate and stick with hydraulic lifters. I don't consider the turbos restrictive, 60-1 .69 A/R p-trim T4 on each bank, but they certainly aren't big. This is a pump gas car which might make use of methanol injection for a little more timing, AFR, and boost at the unsuspecting moment.

Who should I call for a cam? I would prefer to find someone accustom to turbo cams, but beggers can't be choosers, huh?

Thanks

I would suggest a cam with the following specs:

Adv Duration-----288*/292*
@.050"----------226*/230*
lift with 1.5 rockers 0.532" int/exh
LSA--------------112*
ICL---------------110*
ECL--------------114*

Can't get any better than a custom cam

On a mild turbo LT1, I would definitely do a 218/218-114. Good street manners and proven to 990 rwhp on a mild LT1 with a T76GTS.
