Mixing cam and Lifters
« on: September 17, 2018, 04:41:56 PM »
Am sure this has been mentioned before  but I forgot the answer.  Can you use a hydralic  flat lifter set   on a  roller cam.  Its in a car for the kid, a stock 302,  in a 68 FB.  Oiling  is unchanged  ie, lifter valley, juice lifters and feed to the rockers.  Had this 68 hipo cam laying around, new and unused.

Thanks much

Not quite sure what you're wanting to do, but flat tappet cam lobes have a slight slope side to side so the lifter will rotate.  Roller cams don't have that feature, so the flat tappet cam would eat up the lobe in a hurry.  The ramps on the roller cams are often much steeper, which wouldn't be functional without a roller lifter.

Thanks Janeson

The cam is a mechanical flat tappet  not ground to be a roller.

Mixing is a good way to be back in the motor real quick.  Either run the lifters that match the design of the cam, or get a hydro flat kit with lifters. 

This is a good all-round cam spec for a 302
