302 "roller" basic question
I have a '91 F-150 with 5.0. It's time to think about engine rebuilding. Easiest for me would be to build one, and swap it in. So....
When I see a block for sale that's for a 302 "roller," that's referring to how the valve lifters work, right? What is the actual difference? What parts from my stock 302 can I re-use? Same heads? Is there any advantage/disadvantage to a roller engine? Is there any difference other than the heads and cam itself?
Sorry for the basic level questions, but I can't find this info.
Thanks,
Chuck
