So, I found out that GMC used a separate motor in the A.D. TRUCKS. Trucks either had a 228 or a 248 , both being full oil pressure with insert bearings
So, now my question is ,, did all the engines use the same block or was the GMC block bigger ? Are these GMC engines hard to get parts for ?
Thanks, Charles Pretzer
