Possible engine for Cab 13 C15a

[Bob Carriere]

Hi Hanno

Bolt wise they would all fit the bellhousing.....GMC 228 or 248 or 270.... however....HOWEVER..... they are a tad bit longer and something has to move......

Rad clearance would become critical.... I had a 248 in my cab 11 and the fan was about 1/2 inch...for Hanno 12.5mm.... but the rear end tranny connection were stock......

I beleive the Caldwell had a 270 in a modified HUP and the engine cover had been removed for rear clearance.

BUt like Barry I feel a fun to drive auto cab 11/12 might be the trick..... I will consult some local rural mechanics for the elusive short 3 speed auto used by GM in Vans....coupled to a good large six it could be fun to drive and might only necessitate minor adaptation........ I am not to keen on butchering up a CMP frame and beleive me if I need to remove or relocate crossmembers I will carefully remove and re-drill to re- install....... the trcik is the short space between the tranny and the T case.

I tried to keep my original 1959 4 speed "fully synchro" with the 261 engine..... but the modern 59 tranny was almost 4 inches longer than the undersized original 216 tranny leaving no room to connect to the T case...

I did meet a gentlemen in one of Oshawa's show that apparently had a modified C60 that he was driving around everywhere claiming that the mods (not sure if it included and auto tranny) made the whole difference....... anybody knows who I am referring to?????
