That's exactly what I suspected, and precisely what I need to know. You're the best!
Now its making more sense. The motor made 160 hp in stock trim, with the orig cam etc and smog stuff. Right? And with the changes he made, who knows how much hp the thing has now...or torque. I need to find a dyno.
I know he changed the carb, cam, intake and exhaust. I can see and hear those things.
My guess is that he probably left the pistons, rods, crank and heads alone. (Plus it still has contact breaker points.) Otherwise he wouldn't have put in such a big cam!
And THATS why I have hardly any vacuum!
Now then, what has the biggest effect on vacuum... cam, pistons or heads? I believe the pistons determine compression, right? or do the heads help there too? (Man, I better take a course or class!)
See if this makes sense. He already changed some of the items, so if I replace the pistons, rods, heads, and ignition, and have it all tuned, I should have a pretty strong motor, yes? If it was a truck motor, the crank should be heavy duty.
Am I on the right track?
