As my 302 sits in a machine shop, I'm looking for cams to install in it.
I know it currently has a flat-tappet cam in it, but I'm wondering if this block is roller ready?

That is, can I convert use stock 5.0 mustang cam, lifters, and dog bones to convert this block to roller, or would I need to use the special retrofit lifters/small base circle cams that many company's make?

This is in my 89.

Thanks.

An 89 block should be roller ready from the factory. If it came in your truck/bronco it wouldn't have a roller cam from the factory in 89. If it isn't a roller block you can use a roller cam and the expensive link bar lifters anyway. Depending on your particular application it may not be $$ worth it to convert. The lifters were expensive the last time I saw a price on them. (Like $400 for the set expensive)

If it is a roller block, all you would need would to do is rob the parts from a factory roller. Lifters, dogbones, cam, etc.

Does the valley have the screw boss for the hold-down? If it does, than your block is roller ready. You only would need the hold-down and 2 10mm screws and the metal or plastic dogbones for the lifters.

Even better if your block has the screw bosses all you have to do is get a factory roller lifter valley plate setup off of a mustang from the j/y a new set of factory lifters drill and tap the bosses install cam, lifters, lifter plate and then bolts.

If your block is not roller ready then you should be able to get a good roller cam core from a junk yard for less than you can modify your existing block. I was in a similiar sitiuation and found that to adapt my non roller 351 was over $1000 to do it right, and the $400 lifters are for the small base circle cams. For my build it was not worth the effort, with luck your block is roller compatable.

Thanks for all the replies.

When I dropped the engine off at the machine shop I was sure it was a roller block, but it's been so long since I've had the intake off my Mustang I wasn't sure. They are supposed to call me when they get it torn down, so hopefully they can tell the difference.

I will post up when I hear the final word.

Perhaps it's time to start a build thread.
