I'll bet they're made in China. That's where all the other cheap copy cat parts are being manufactured
No response from either seller, guess Ill fork out the big bucks for a name brand set, unless I get lucky and find a set used.
Reduced base circle cams can bend and twist with high rpm and stronger than stock springs. The best, though more expensive way, to put a roller cam in a non-roller block is to use a full-sized cam, not a reduced base circle, and Crane link bar lifters. They are a drop-in affair. No drilling required and you can use the lifters in any block, even a roller, and they will out-rev the OEM lifters. If someone put an E cam in a non-roller block with stock lifters and hardware and had no oil pressure issues they are extremely lucky.
How "pre-roller" are you talking? I put roller rockers, lifters, dogbars, spiderbones, etc. (or whatever they are called) in my block but they were on an 88 model "pre-roller" block. They had the two nipples (heh-heh!) in the lifter valley that would allow me to drill and tap a couple screw holes to mount the spider bar doohicky thing-a-mabob. So if it is a "302" block, I am of no help, but if it is a pre-roller block with the nipples, you should have little problem adding the roller stuff to it. My cam DID have a smaller base-circle but only on the exhaust valves, to give them extra lift, and I used lash caps to take up the slack. It is a fairly wild cam, though. A moderate came should be able to fit in there without it.
I used the Crane link bar hydraulic rollers in my 77 Mustang II with an E303. These are pricey at $500 set, but much better than running a reduced base circle cam. With the Crane lifters, you can run any standard hydraulic roller cam, whereas you are limited in grind choices going with a reduced base circle.
Your block is a roller block regardless of what cam Ford originally had in there. There were no non roller blocks made after 1985.
