Re: stroker kit
The cams you choose are going to be very dependent on your goals w/ the vehicle. Since I don't have a turbo and am trying to get the most power possible, I have to pretty much shoot for the highest RPM possible.
My current cams are 270* deg / .440" lift, LSA 110* from Schneider. So far I've liked them a lot, but I'm looking for a more aggressive grind. I'm going to have custom cams made by Isky, the specs I'm shooting for are 286* deg. and .480" lift with an LSA between 107 and 109*. This would give me a nice large overlap: very lopey, rough idle, no real torque until 3k RPM, but should be able to rev well past 7500 RPM while still making reasonable power.
Just a side note: Those JWT cams you've selected are brand new cams with stock base circles... so when they say "the biggest that will fit w/o modification", they are correct only as long as you keep the base circles at the stock diameter. Isky, Schneider, Colt, and others do regrinds of stock cams. They grind down the base circles a bit in order to get the specs you want, but obviously there are limits and it largely depends on the shape of the cams before they start working on them. However, regrinding stock cams gives you more flexibility and the ability to get an aggressive grind that you simply cant get w/ stock base circles.
Another thing to consider, if you're really trying to do an all-out build for maximum power, is modifying the lifters. SATAN has done a very nice write up on modifying the lifters to make "semi-solid" yet still self-adjusting hydraulic lifters. Doing this allows you to go with a much more radical cam lobe profile that you just can't use w/ stock hydraulic lifters. Look either at 88hybrid.com or z31performance.com for his writeup on the lifters.
