I'm sure you want to pick up a few ponies as soon as possible...but.....
TRy getting a used intake already ported( i got my cobra w/ upper and lower both extrude honed for $425..same price as new untouched)
I also just picked up a set of edelbrock aluminums..for $600.
At least try to find iron GT-40's..(off a cobra)
I bought a set one time for $300...get them decked and clean up the exhaust ports..you'll pick up quite a bit.
My buddy runs 11.40's w/ cobra heads like i just said, GT-40 intake (unported), 5-speed, 125 dry shot, slicks, exhaust, suspension....

4.10's,long tubes & 75 shot...Goes 12.50's
