Not bad. Carb probably did hold it back, maybe just a little more than some.

It should make for a nice tractable street engine, but the solid roller and bushed lifters seem a little overkill for the rpm range. Do you plan to put a single plane and bigger carb on it? Was that peak numbers? It looked like the test started at over 4000 rpm, but you stated torque at 3500. That seems odd. Nice engine, not trying to knock it by any means.

Much more likely peak torque was at 5500 not 3500 since torque and HP are always the same at 5250.

Planning on replacing the Performer RPM with a Torker II or a Victor and use my 1200 CFM FAST EFI with 62 Lbs injectors. That should pick it up across the board.

Peak TQ is at 3500 - It is a Pontiac


The Dyno was run in two halves. 4000 up and 4500 down to get the low end of the TQ band. The engine was not getting any tuning beyond getting the timing at the sweet spot for the carb we had. It was a borrowed carb set up for a totally different engine. We could not make changes to the A/F on those passes.

I'd roll with the Victor then dyno it. I've got mine stashed away for a rainy day.
