So my car is pretty much a stock 91 gt and im looking to gain about 60 horsepower (or more) and was wondering some suggestions on what to look into getting. I do want to mod my car but i also want to beat this jerks 94 lt1 camaro thats got about 50 hp on me.
Im also not really into the idea of NOS so thats counted out

86 5.0L

125shot of nitrous + sticky tires

How much do you want to spend? Bolt on a set of Trick Flow TW or AFR 165s will give you about what you are looking for.

Get a really nice set of heads and an aftermarket intake with a new exhaust setup that should do it. Even though you don't like the idea of nitrous that is going to be the cheapest way to do it if you're on a budget.

heads are about the only option since u dont want nitrous

altough it wont add any HP, a set of gears will go a long way in the pursuit of kicking the LT's ***

I beat my buddys 1996 Trans Am wich had an LT1 with a GT-40 intake port and polished, 373 gears, CAI, underdrive pullys with full exhaust we went from a 15-20 roll and I pulled 2 cars on him hope that helps.

Your budget has a lot to do with it but ideally you'll want gears with a head/cam/intake swap and a dynotune.
