That’s possible. Here’s why….

Probably not likely, but cams can be ground with a smaller or larger base circle than what cam as stock.

Even if it is ground on the proper diameter base circle, the new lifters can have a seat height difference. There was over .100 between my MP solid lifters and the Comp Cams solid lifter. That my dear sir, is gigantic!

This issue with lifters are, where the plunger sits and how far down the pushrod pushes the plunger down. There has to be some travel. This amount differs from lifter to lifter manufacture to manufacture.

The only good thing is if you stick with a MoPar lifter, the seat height (should!) always be the same for whatever style you are working with.

Comp cams has 2 tools which IMO everyone should have and that’s adjustable pushrods for checking length & a 12” dial caliper to measure the pushrod length.

You could just roll the dice and see if the pushrods fit in between the rocker arm and the lifter while it is on the cams base circle.
If the pushrod doesn’t depress the lifter or is just outright obviously short, then ether get the tools or call a buddy over that has them.

I’m sure the pushrods will fit if you use MP lifters. There’s no issue mixing lifter brands and camshafts.
