I think I've read that the radiator has to be moved forward due to the extra length of the GMC engine. Is this right,& what is involved regarding hood modifications etc? Are there any alternative solutions? I'm not concerned about running gear adaptions, as long as it is realistic to physically fit the engine into the engine bay.
Do the same problems exist in the heavier trucks of the same years?

Ken, here's a link to the Tech tip Old Sub mentioned. If you haven't already, join the discussion group at oldgmctrucks.com There's a guy there running a 302 in a '37 Chevy truck. | | | | | Joined: Jul 2005 Posts: 71 Member | | Member Joined: Jul 2005 Posts: 71 | Thanks fellas
Rusty - I'm not anti-V8, but I'd go 270 for this project to stay closer to original & still have reasonable pulling power.
We've got several 270's lying around just waiting for a use.
I've joined over on oldgmctrucks.com - Thanks Cletis, I'll search through - excellent site there too | | | | | Joined: Oct 2001 Posts: 3,458 Extreme Gabster | | Extreme Gabster Joined: Oct 2001 Posts: 3,458 | Let us know how it comes out, I'm about to put a GMC 302 into my '50 1/2 ton. I'm excited. I'm probably going to put a Howard log manifold on it, I have a set of Holley 94's in my garage just waiting for a home.
