463 rwhp SAE, big stall A4, mods in sig, on a Land and Sea Dyno. Still working out the kinks!!!

Made that power with a burnt plug wire and number 2 cylinder leaking compression into the coolant system. Old head gaskets with 13.2:1 CR. New gaskets running at 13.9:1 CR, back to the dyno soon.

96 LT1 Z28 w/ magnaflow 3" cat back and K&N CAI

293hp/311tq

Quick question. What would be more beneficial for low end power and grunt, LT4 hotcam kit, Comp cam kit? I'm looking to pick up 20-30+ hp. but I don't wanna start tearing things apart and changing things around. Any help making my more decissive would be appreciated. Thanx

250whp/300wtq

my air/fuel ratio was idle at 16.1 and at 4500 rpm, leaned out severly....need to upgrade my fuel pump. what do you think it should make with a dyno tune?
ok i am pretty sure i found out my problem. Put a fuel pump inn the truck, walbro 255 pump and WOW did it give it some power. Still a mail in tune, but it definatly pulls farther than the time i took it to the dyno n it had the issues above ....at 4300 rpms it leaned out big time, shot up like crazy

So what do you think i should be at power wise? the guy that did the swap says that i should gain a easy 20-25 hp from this fuel pump alone since it was choking the motor with the old pump.

Any chance 300whp/330wtq is possible with my setup?
