Drag race W8 combos ran larger than 4.2 bore where you are 4.182". P7 valve angles are also different. The whole shape and design of a W8 drag race head is different.


I truly hope I am wrong. Hope you have the ticket. Just know my experience. Could have sold you 8 pistons. One you could test your welding talents on. Keeper scuffed it just a little LOL
