RPM Airgap

I'm not a fan of mixing parts. But there is nothing technically wrong with using the pushrods as long as the geometry is correct. Wouldn't do it in a performance package setup. As far as the ob-longed holes in the intake. Makes it work for both old and new bolt patterns.

Thank you for the reply.

is there more than one stock length push rod for a 85 360 ?. That's the problem with stuff that you did not put together and know nothing about. But I assume the geometry is good be used it runs good it's not noisy and I run the car pretty good at times. I suppose the holes could be on longed because block deck and or heads were modified or maybe the heads are newer and older intake would not line up.

I'm not sure that I want to or should hog the holes out on my new intake and if I have the intake modified it pretty much makes it good for only the setup it's currently on.
