Whats involved in fitting a Roller Cam?

Considering a roller cam for the clevo, what mods are required?
Can one fit the 5.0 weezer style (2 joined) or do you have to fit the guide bracket thingy? Are any direct drop in or is sleeving the lifter bores required etc?

Re: Whats involved in fitting a Roller Cam?

You use drop in link bar lifters. The spider is a Windsor piece.

You also need matching (shorter) push rods, valve springs, distributor gear, and of course the cam itself.

Re: Whats involved in fitting a Roller Cam?

The Windsor style spider should work just fine with your Cleveland. I'm using the stock FMS hyd roller lifters with the spider setup and haven't had any troubles with it. I shift at about 7100 rpms and nothing has let go yet. If your going with a hyd roller cam and not going to wind it way up, I'd go with the spider and FMS hyd roller lifters. It will save you some good cash.
Just my opinion though, I'm sure others will chime in.

Re: Whats involved in fitting a Roller Cam?

Using standard roller lifters in a non roller block means you need to use a special small base circle camshaft - not the best way to go if you can avoid it.

Re: Whats involved in fitting a Roller Cam?

I agree with racer i used a small base circle hyd roller cam with windsor rollers & spider
& bent pushrods every time i hit 6500 ,tried upping spring pressure & lowering pressure as cam blokes were suggesting but bent everything from hardened to chrome molly .080 thick pushrods so have a spare set of hyd lifters & spider on the bench now (cheap ) lol

Re: Whats involved in fitting a Roller Cam?

So I guess the lifter bores arent deep enough to run rollers without block mods?

When you say "non roller block" are you referring to windsor?

Re: Whats involved in fitting a Roller Cam?

what happens is you run a windsor lifter but run a smaller diameter cam so the lifter sits in the bore about the same height as a non roller lifter .

Re: Whats involved in fitting a Roller Cam?

Found this setup but would perfer solid roller type! I dont think you need to install spider for these? Does state block mods are required?

What were you running for a cam, size wise? The first one I had in my Cleveland was the Comp Cams 304HR. It was 244@0.050 and 304 adv with 0.612" lift. I was using the stock type Ford roller lifters with the spider. I was running Crower springs that were only rated at like 108# on the seat. I had that engine at 7500 rpms a handful of times. Then I switched to my MME custom hyd roller cam, 242/244@0.050, 285/287 adv, and 0.640" lift. I still run the stock roller style lifters and spider. I also upped the springs to 160# on the seat. I take this engine to about 7100 rpms and have no problems. I also run the Hi Tech Comp Cams pushrods. The guy that grinds my cam said that they have engines going over 8,000 rpms using the stock roller lifters. As long as the preload is 1/8-1/4 turn, you shouldn't have any problems. The small base circle usually doesn't cause problems, like unstable lifters, until you are 6500 rpms or so. That is as long as you have springs that can handle it. Most hyd roller setups are recommended to rev over 6500, but if they are setup right, they will usually hold up above that. Just my opinion.
