I have a 1988 firebird V6....any ways to modify for more horsepower without the obvious
motor swap out?
Forget it, swap out for a faster car, try looking at a Subaru WRX STI.
Yes, add tube headers, aftermarket cam & kit, modifiying the cylinder heads, use the valve springs in the kit, port & polish, mill a few thousands off the heads. A local cylinder head shop is your best bet. (I've seen Chevy V6's that make almost as much hp as V8's) Buy & install a MSD ignition box.
