except the stall converter seems to be an easy add on, that you suggested, so I will add that & the Intake & carb, but hold off on the cam replacement

Your engine is made of a lot of mis-matched parts, but it will run. A lot of people think that if you pick a low RPM cam and high RPM heads you get the best of both world- in fact you get the worst of both worlds.

For now it is what it is, but you need to decide what you want out of the engine and then modify it to fit that goal. cobbling a bunch of cheap parts together will get a car moving but it will be far from optimal.

Everywhere you read they say it is bad for torque to run big cc heads with a mild cam. And the dynos show the same thing.

However, I had a different experience recently that makes me not care so much about that.

a friend of mine build a simple 350 (9.3:1 cr) with a th350, 2.87 rear gear, and a stock stall. Has a little 260H compcam in it. He had old fuelie 2.02 double hump heads with 64cc chambers and 165cc intake ports. The heads kept blowing exhaust header gaskets so he tried a set of my 200cc dart iron eagles. And we felt no performance difference in the low rpms and maybe felt a little stronger on the top end. Really hard to tell any difference at all. Surely wasn't a super noticeable difference as you would predict from reading engine tech articles.

Sure, I try to match my engine components according to the "standard" but I don't think I will worry too much if the heads are a little too big for the cam. Especially since your engine is a 383 with a 3.42 gear.

check out his web site. http://www.ryanscarpage.50megs.com/combos2.html

combo 11 is about what you have. also notice combo 12 which is a 350 with biggish 195cc heads and also has a cam about the same size as your.
