The owner is doing the work himself, so the engine won't see an engine dyno. He has no plans to put the car on a chassis dyno either, at least not at this time.

The intake valve is reaching max. open about 7° earlier than my typical camshaft. That's a very positive thing. But on the other hand the intake valve is closing 10° earlier than my typical camshaft, good for dynamic compression, not necessarily good for top-end power. Definitely no reversion issues
. With 60° overlap the engine will have a nice Boss 351 kind of burble at idle. The engine should have great low rpm power. The owner is doing his own head work. he's got them on the bench right now. I told him to blend the seats into the combustion chambers, clean up the valve pockets, round & blend the intake pocket throat without making it any larger. He purchased a set of Manley racing valves for the intake. Afterwards he'll get a 3 angle valve job. The engine is getting a new carburetor, the Duraspark distributor is getting rebuilt and re-curved. He's keeping the Edelbrock Performer intake for now, no budget for another intake, but I advised him to block the manifold's heat passage. If he does a good job with the rings I told him he should expect 425 bhp at the crank, 340 at the rear wheels. Sounds realistic doesn't it? Not bad considering the engine started life making about 260 bhp, the only big changes are compression, cam, and carburetor. Just unfettering the charging rhino.
