i have a 96 z28 and i have done some performance work like a new comp cam, new heads, larger valves, an slp intake, an slp strut brace, k&n air filter, flowmaster exhaust i had it dyno tuned and i got another 20 horses out of it to put me at 344 rwhp i was wondering what else i could do to get more ponies to my wheels and still keep it na also can anyone suggest a transmission that could possibly replace my 4l60e or maybe rebuild it with specific parts i do not know very much about cars my friends here are my only help and are the only ones to offer insight so if anyone has some input i would appreciate some replys thanks a lot z28fan

LT4 intake manifold will get you another 10 hp at least. Keep you 4L60E, just get a higher stall and rebuild it with HD parts.
