87 r10 305 tbi 700r4. There seems to be quite inquiry on whether the trucks had roller cams in them or not. Does anyone know how to find out what came is in a vehicle without diving into engine?

FWIW I rebuilt a 350 TBI that came out of an 87 Sub for my 37 and it did not have a roller cam as original

The OE R/V truck engines weren't fitted with roller cams. Only the car lines had them.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

The provisions were there though so you can change it over easily.
