I'd like to add more power.. Any suggestions???

strip dominator single plane and IMM engines Indy X-heads are a good way to get more horses. Try and find a good Thermoquad to keep velocity up with Holley Strip intake. This worked wonders for my 360 280/474 cammed motor in a 1974 dart sport fun mobile!:burnout: I also have 3.55 gears and that is plenty. 4.10's not needed in my opinion. Just better tune and attention to details!:glasses7:
