GM 366

[c10chevy]

I have a 78 c10 chevy stepside that currently has a 5.7 diesel in it and I want to put somthing with more power in it. I also have a 74 Gm with a 366 in it and I was wondering if that engine was worth rebuilding to put in my c10? Any of your thoughts about this would be great.

366 is definitly worth it, we put a 80s goodwrench crate 366 out of a 86 GMC tow truck in a 64 c60. That I am restoring.

 

Is got enough power to get the truck sideways on dirt!! Duals!

366, is that the small big block they used in medium duty applications?

Probably, it came out of a 1 ton( I think) farm truck

The 366 is a big truck engine that was used in 3 ton trucks. Slow to rev up to speed, more than likely because of the heavy flywheel. Lots of low end torque but not a racer.

What you really want is a 396, that engine will blow the doors off anything. It was common in the early 70's.

Yup, a 366 is the baby big block. It has 4 bolt mains and a forged crank, too.

Just as he said.

 

It was meant for long service life in large GM trucks (2 ton and up).

 

Racers used to make the "original" poked and stroked big blocks, but this have fallen into disfavor.

 

As far as the installation, it should bolt directly to your mounts and trans, and due to the fact you have a diesel, the radiator should be fine.

 

I think with normal maintenance, this engine should run forever, and a lot more power that the diesel.

Those engines were tall deck. If you can find kits, you can stroke them to the moon.
