360 dyno

It's a shame to have to agree. But even considering this could be a very stingy dyno, it looks like no more than 266 hp at the flywheel.

I'm thinking there would be some more with a proper tune.

Yes, I thought it had headers for the range I original gave.

It's probably a 300-310 engine and missing some on the tune up to have the current results..
