1/4 mile and rwhp estimation

i once owned an 88 iroc and i liked the car and now im thinking about getting another one cause i keep busted my trans in my zx2. pics below. i still have a set of new 3.73 richmond gears that i never installed. to my question. if i get a good running 350 tpi 700r4 third gen and i put on headers, 3 inch exhaust, ported plenum, deleted smog pump, afr set at 46 psi, tune, and 1.6 rockers. what should i expect in a 1/4 mile and rwhp?

cam/heads and probably intake would do the trick

Re: 1/4 mile and rwhp estimation

would the vortec heads and manifold provide enough air flow?

Re: 1/4 mile and rwhp estimation

The vortech heads and intake are a good popular choice for a good setup.Nitrous oxide will be yor best bang for buck.I`ve seen bone stock 5.7 tpi hit 12`s on that stuff.Make sure your fuel system is up to the task.Check out the tech articles off of the home page.It has an all about nitrous oxide article.
