Alright, I reached that point where I need to start putting together a motor for this spring. My last setup consisted of a stock 5.0 with asp underdrive pullies, a systemax II intake, fox throttle body conversion, and a PTK turbo kit running at 9.5 psi. Well I found a buyer for the PTK kit and have the option of getting money plus a set of AFR 185s with the spring upgrade and 1.6 roller rockers or just all money. But needless to say I don't even know if I wanna go 351W yet or 302. The way the mustang was running last time it was fast as hell and didn't even get pulled on to badly by a modded 04 cobra. But thats nto enough for me. Unfortuanly I dodn't even know what I dynoed at because I was running pig rich to begine with. I got a set of twin turbo headers coming as I'm gonna be building a TT mustang now. But I don't know if I trust running a stock 5.0 block and have no where near the money to budget in a dart block at this point. My final combo would probably be a 331 or 347, AFR 185s, F303 cam or stock cam, systemax II intake, and 10 psi. But I don't know if this would produce block splitting power. Which is why I was thinking of just going 351 so as to not have to worry about it. Can anyone lend me an opinion.
