Nice Al, very good results.
You going to do some head work?
No! If I was I would have done it first. It's just a street engine.

A impressive one! :D

its got a torque curve flat as texas ,,, i bet it does good , try any spacers ? looks a lil bit lean down low , did yall try any changes ? ,, just think if they would have been ported some ,,, those heads have great exhaust ports ,, like 'em , don't like 'em , they can do a decent job with some help

Nice job Al, thanks for posting the dyno sheet. Just goes to show how easy it is to build a nice stout street engine.
