Okay,

I just purchased a 96' LT1 cam from a guy on the camaroz28.com board. I have a 91 LO5 from a suburban. I also have a hydraulic Dana cam in it with 204/214" @ .50" with .420 and .442 lift. I am going to switch to the LT1 cam maybe this summer. I also have Comp Cam's 1.6 magnum roller tip rockers. What kind of performance gains will i get when switching to the LT1 cam? I plan on leaving my stock heads on the truck. I might pull them just to have them cleaned up and portmatched to my intake. What do you guys think? I don't wanna spend a $1000 dollars on heads. Also, will I have to do any ECM mods? I already have a AFPR on the TBI unit.

Don't bother taking off the heads for just port matching. The L05 heads are swril port heads and have a ridge in the intake port. Either plan on getting rid of that ridge and doing a pocket porting or just leave the heads where they are.

 

How much do you think it would cost to have that ridge removed?

thanks

Depends on the shop. Call around but I sugest not doing much to the swirl port heads. They aren't usually worth the effort. Better off getting vortec heads worked over for like $500 to accept the higher lift. Then just get a good intake.
