1972 Chevy El Camino 350 Engine Rebuild - El Cheapo

By , Photography by Terry McGean, ,

Things We Would Have Done Differently
• We paid too much for the trans and converter. Junkyard units might have been $50 total, and the risk isn't that much greater than with a swap meet unit. A stock converter would work better with the yukky 2.56 rear gears, but the one we have will be great if we swap to 3.73s.

• There wasn't a really good reason to swap the intake manifold for an initial just-get-it-running effort.

• Nearly anyone will tell you that our 800-cfm carb is totally wrong for this application, but you sure can't tell it by driving the car. Besides, we totally ripped off some guy when we paid only $50 for the sucker.

• The cam duration seems a bit too much for this engine, which has 8.5:1 compression at best. A duration of 214 at 0.050 may have been a wiser choice. Even with the 224-at-0.050 cam, it sucks 15 inches at idle.

• We're terrifically lame for (once again) not printing quarter-mile numbers for the Elco. It just plain didn't get done in time. Don't try and tell us that's never happened to you.
