The GMC CCKW

Ok a couple more questions about the 235 and 270 engines.

1. Are the exhasts and manifold connnections the same or is the GMC a larger bore pipe?

2. Do both the Chevy 1 1/2 ton and GMC have the same radiators?

Thanks again

GMC has larger bore pipe and does not use a donut

A chev radiator will fit a CCKW (I think) but a CCKW rad it too tall for a chev
