compression
what's the best compession ratio for a bbc 632 that would make the best power? I'm looking to purchase a short block, my heads are dart 360 cnc.

Most of my racing is done at 4800 ft. not ajusted.Average ajust is around 7500 ft.
|
Depends on the gas your going to be using. We typically do 15 or 16:1
|
I currently use 114, I can go up if i need to. my comp now is 14.5 to 1. I wouldn,t mind going hirer if it will produce more power without problems.
|
Who's 114 octane, there is a huge difference between fuels brands. Adding Compression alwasy increases power.
|
The higher the compression, the better the parts need to be.

I think those heads will be what limits your hp unless they've had some hand work done to them.

Or do we just bump the timing a couple and suffer on the top end? Coming from Bear's dumbassed old crew chief . . . . |
