I'm looking at building a 408, getting a 351 1994 lightning block this weekend, with AFR 205s, 10-10.5:1, Trickflow-R upper and lower, hydrolic roller cam, fuel injected( I know I need to upgrade to a 255 in the tank, and at least a set of 42lbs ers). Gonna leave the spray on my car so I may use it. It will be a summer daily driver, as well as a strip car a couple time a month. Car has a t-5 with Astro gears that I will leave in there for now. I would like to see it at the 500rwhp level. Was looking to shift at 6,000, but If I have to go to 6500-6700 I will but I would rather not. My car right now is 3530 with me in it.
