You're right Blind. The small base circle profiles aren't quite as aggressive as standard 5.0 stuff - but I think that's likely a non-issue for most folks. Ed Curtis has nutty ramp rates anyway. :)

idk, i have what was said to be an 86 block from a truck and it was not a roller block-didn't even have the spots to drill and tap some, so i had to put in the link-bar lifters to convert it.
Yes, I said 89, not 86, that's all I can be sure about is what I saw. I also saw a late 80's LTD/crown vic 302 that was the same way, pads were there for the bolts, but no holes and it was a flat tappet cam. Just passing out some info I am sure of. Can't comment on other years/models. I know the trucks got roller cams sometime in the early nineties for the 5.0.
You can also use the crane link bar lifters and use a standard 302 style base circle roller cam. That's what I am using on a 393 I am building for another project car. I am grinding one of my custom grinds for it or maybe using a tfs stage 3 for cost savings.

Nah. All I did was drill/tap the block for the spider retainer, then use OEM lifters/dogbones. Ed Curtis cut the cam and it was no problem.

Paul.

the cam is critical, and can't be as radical as a true roller blocks cam can be, the 351w I'm building right now is a `91 block and will need what's called a 'small base circle' cam so that the lifters don't stick too far out of the block and get proper oiling.

or you can buy link bar lifters and do it correctly so you arent limiting yourself on a cam
