Roller 360

I agree with 340mopar you can use a flat tappet cam in the roller block no problem. Another option would be to look at a reground roller cam for about $120. I see them on ebay sometimes or you can send your stock cam to a company like Ultradyne. Then use your stock lifter setup.

If you 90 360 is a TBI motor then it you should have 308 heads.
