Ok,
Here it is, My 1947 Chevy Loadmaster a well-used old farm truck. Originally it had a 216cid low pressure motor. It’s gone and at some point a 1962 standard car 235cid ( F1201A) full flow motor was installed. The 235 was longer and the radiator has been moved forward to accommodate the longer motor. At some point in time the old truck got parked and stripped of its hydraulics / dump bed and gas tank. This was around 1985ish from what information I’ve gotten from the previous owner and her Mother. Kind of funny she said the truck has been there in that same spot all her life.
Ok, I got to the house and started working on it. Mostly just cleaning it up and discovering what I really have gotten into. The cab is in good shape all the glass is in it with BB holes. It has a 1962 235cid in it now install by the previous owner. I got the motor started and it sounds a lil rough lots smoke LOL. At with a little bit heat the bottom end started to knock. Hmmm.. Now I know why it was parked. Old strait six wasn't readily available in the mid 80’s.
I found a GMC 270cid motor over in Butler, PA ( 2 hour drive ) It looks like it would be a fairly simple to install. Mod the front motor mount and the move the radiator forward a little more.
The Pros / Cons of installing a GMC 270.
I do NOT want to install a V8 of any kind.
Pros
270 is a rare TRUCK motor.
270 is just plain cool.
270 makes more horse power and torque than the Chevy 235 or 261,
270 can be modified / Hot Rodded. At a price!
This 270 is complete and running carb to pan / fan to bell housing for less than I can rebuild the 235.
Cons.
It’s not a Chevy. (Although the 235 is not original) Chevy 235 is cool just not as COOL. LOL
270cid GMC can be very costly to rebuild.
270 are rare and hard to fine parts. Also hard to find a Machine Shop that have the knowledge the to do machine work if needed. (Same can be said for the Chevy 235)
This 270 is running but I’m concerned about watching the distributor wobble while it running. I’ve read horror stories about this in GMC and Chevys. To me it sounds like the rods are starting to knock or is it just the way GMC 270s sound. I’ve never listen to a GMC 270 run before.
With the Chevy 235 I don’t have to move anything it is already done.
235 parts are more readily available.
Hummmmm…. I need a lil help from my friends. What would you do?
