Money
Sorry couldn't resist plus i don't have money or power.

 

Heads/Cam would be the next step if I had your mods. Heads arent so hard to do if you are somewhat mechanically inclined. The cam is a bitch, though. Theres a thread right above/below this one titled 'My heads/ cam install'. Check it out.

 

Other options:
UD crank pulley, EWP, ported TB, 1.8 or 1.85 ratio rocker arms(w/upgrades valve springs), and finally vehicle weight reduction.

 

Not really a power adder, but a huge improvement...A good set of tires.

Unless you already have some.

 

ported/modded tb/, cutout, underdrive pulleys, PS bypass(just a belt) and a good tune. Suspension is a good way to get it to the ground as well.

 

FWIW, gains with all of these will be minimal on an otherwise stock longblock. However UDP, rockers, and springs will show a nice gain with the right cam.

 

Just making sure he's aware of his some other options.
The EWP also shows a nice gain by reducing parasitic power loss;but it's pricey!

 

I have 315/35/17 kumo mxs. pretty good and umi tq arm and lower control arms. With strano springs and bilstin shocks. Also strano front and rear sway bars. Were i live the is a 1/4 mile oval track that runs on Wednesday night and thats what im setting the car up for.

 

go to ls1howto.com for instructions on heads/cam swap.whats your budget?

 

Heads/cam is def the next step. Where are you located?
