Thread: V6 90 degree vs 60 degree engines question

Tweet

The 60 degree Chevy motors have a bad habit of blowing head gaskets. They will not bolt up to a 350. However, the small bell housing 700R-4 is abundantly available and cores are cheap.

Edelbrock makes an intake.

FWD 60 degree V6 motors an be adapted to rear wheel drive using a modified small bell housing 700R-4. A lot of work, in my opinion, for very little return.

The 4.3 chevys are good motors. They were used in trucks and vans. Every one I have taken apart was well used. You want the late 80s motor but you do not want the 90s motor with the ballance shaft. Edelbrock makes an intake. You can also get a four barrel cast iron intake off an Astro Van. Hazy on the exact year (84., 85 or possibly 86). Dave Ray can build you a distributor.

I am not an expert on the Buick V6 engines. They were derived from the 300/340 V8 which was in turn derived from the Olds/Buick all aluminum V8.

If I were looking for a small motor to run in a Model A I would consider a Buick, Olds or Rover blocked 215. They are a bit longer than the V6s. But they offer economy with good looks and performance. In fact, I am building one now. It is adapted to a small bell housing 700R-4 transmission. With a cam, four barrel carb and intake, and headers I am expecting 190-200 hp. That will move a Model A down the pike just fine. D& D Fabrications offers a lot of stuff for these motors. http://www.aluminumv8.com.

Just a thought.
