Trying to remember from bygone years which roller rockers can be used on a 250, I have 2 boxes, 1 marked BBF and 1 BBC, they been sitting since my i53 dragster days gathering dust. Just don't remember if either one will work.

BBC will work but they are 1.70 to 1 instead of 1.75 to 1. I have read that some Ford works but not sure which. The guys that sell the pricey Chevy six sets say nothing else works.

They are all pricey. I have used BBC 1.7 in the past. But the correct ratio is 1.75. With any of them, you will need to measure pushrod length and order the correct length.

A quick check of Summit's website shows a large number of different rockers (btw-I eliminated 1.7 ratio rockers.) They are for 396 BBC, all 7/16 stud. I'm sure other things need checked?
