Is your engine already built?
Like 66fs says, the A-230 is very capable. But you will need all 3 gears to et.That means race gears. Which means, no more comfy cruising. Dual purpose is pretty much gone.
There is/are some options; A)The 2 chunk system, for the occasional dragracer,or B)More tranny gears.Use 3 for racing, and the fourth for cruising,or C)A 2-spd rearend,or D)An overdrive unit, or E)A bigger motor, or F) BOOST
Boost has the distinct advantage of not requiring any changes in the trans or rear gears.Comfy cruising is back.And you can down-size the cam for some mpgs. And 12s are easy with boost.But if you motor is already built, well then I guess Im not helping. I just want a turbo mine so bad.
