I got an 89 camaro that had a 305 TBI, it has a 2.73 - 28 spline rear-end, my 87 SC V6 camaro has 3.42 - 26 spline rear-end. witch one would handle more HP ? my 89 has a limited slip. and my 87 is non-posi.

airfoil
58MM edelbrock trottle body
new paint (wet look blue)

the more splines the stronger the axle all else i doubt would make much differance

the RS rear is better, but if your gears are the same you could swap those ?>????
