Re: Building my 283
Which intake is that that you have??? Is it for a Quadrajet, or 4G?
Sealed Power used to make forged pistons for 283's, maybe still do? I am not sure...
I built a 283 back in early 80's, for my 67 Bel Air (original engine...) I went the extra mile on my engine, had everything done, to the best of my knowledge, back then, and nothing, thinking wise has changed...
My biggest word of experience is to be careful with the cam selection. Smaller engines (anything under 350 cubes!!!), can easily be over cammed. The rumpity sound means you are losing some low RPM cylinder pressure, plain and simple. A 283 cannot afford to lose ANY cylinder pressure, especially in a pickup that weighs over 4000 pounds!!!
THere's nothing wrong with building a 283. They don't start making much torque until 3000 RPM's, regardless of how you build it, they are small engines, it's just the way it is...
The stock replacement cam, Sealed Power CS273 is excellent for a 283, and might be one of the cheapest cams available...would be my choice...
I will post more of my 283 experience here, soon
