Re: roller cam conversion?

That sucks! On Fords, you can just drill and tap for the "Spider" and use a factory set up dog bone lifter holders and roller lifters. All of the 302 blocks are the same from '68 to '95. Sometimes I miss my Mustang.

Re: roller cam conversion?

The cheapest price I have seen for retrofit hydraulic roller lifters for a sbc is $299

http://www.competitionproducts.com/H...uctinfo/91164/

Or for $499 a cam and lifter kit.

http://www.competitionproducts.com/H...info/CL110265/

Starting with a roller type block is cheaper.

Re: roller cam conversion?

Mmm from what I recall building fords, you couldn't retrofit a non-roller correctly because the lifter bores were shorter on non-roller blocks.

Maybe there's a way around that I knew nothing of, but I seem to recall the only option being buying a friggin expensive custom 'short' cam.

Re: roller cam conversion?

Ignore Grumbles, there's no problem ( other than cost ) with using the Howards retrofit lifters, which are $269. There's no such thing as a "short" cam.

Re: roller cam conversion?

I do plenty of SBF v8s too. with those, you don't need an '85 up block to use the factory roller lifters, but even so, they use the same cams as the '85-up blocks.

Re: roller cam conversion?

Shrug. I haven't bothered with Ford motors since my first car which was quite a while ago. I remember looking up retrofit options and finding out there basically were none. If you know how to retro a factory Ford flatty block please do fill me in, I have a buddy building one as we speak.
