Re: High rpm 427 bbc build 940hp?
Wonder what a J. Armstrong Super Stock engine with a tunnel ram bolted to it would make?

Re: High rpm 427 bbc build 940hp?
Back about 1985 had a 420" big block in a 69 nova for SS/BM. Had a crower crank made at 3.60 stroke, alum. rods, alum. bow tie heads, titanium valves, cast tunnel ram and 2 dominators. That motor saw 8500rpm and ran a best of 9.59 at pomona. Really should have run quicker and made more power than it did but we did manage to win the mile high's with it in 1989.
The motor is still in the car owners garage just as we ran it back then. Dominators and all, and he would like to sell it. |

Re: High rpm 427 bbc build 940hp?
When I ran a short stroke I shifted 9400-9600 but never knew how much power 440" motor made. Did not have the $$ to dyno. Biggest problem was the valve train. Was fortunate to have a few really sharp guys help me out.

Re: High rpm 427 bbc build 940hp?
We had a customer that purchased the 402ci D/SM (at the time) from JEG in the mid 1990's. That engine dyno'd at +900hp. I was working at Kromerkraft at the time and we built a set of headers for that engine and gained 5hp. I remember somewhere around 940 or 950 back then.
Thanks, Ron |
