Re: DYNO!!
I'm guessing something close to 625rwhp, but I could be way off as I only really know small block stuff well. Seems like the trans/converter can really vary the dyno a ton also.

Im not real familar with BBC and power numbers either. Has it seen the track yet?
Either way, Im sure its fun to take down the track, or drive around.

Re: DYNO!!
it was an engine dyno and it made 815 horsepower @ 6200rpm and 742ft lbs tq @ 4900rpm.
i had to change from 1.8 rockers to 1.7 rockers because there was valve float from too much spring pressure. the blower backfired pretty hard, lol.
