What is the minimum compression ratio that is required to make this camshaft work as it come with a later injected bvh will be in a rally car at a later stage and wanted to run pump fuel (98).

If head flows well 11:1 compression will be ok

I would start at 11:1 maybe go as high as 12.5:1 but a little extreme , somewhere in between, the rl32 and FR32 has a lot of overlap to help push gasses out which means both intake and exhaust valves are open for a while so you'll need to get the compression back up . 👍

reason for port size port might be to big if going on a 2 litre pinto engine cheers mario.
