Title: Mix n Match Top End
Post by: neilg on November 30, 2016, 02:10:08 PM
Here we go again.
I'm in the process of using up all my odd spares on a project and would value some opinions. The plan is based on a 76 F1 engine. Since the head and cylinder block both have extensive damage, and as F1 oversize pistons are rare, I am thinking of using the head and block from an earlier K model along with the flat top pistons. I can't say what year they are from but they do have the recesses for the dowels on the oil drain side on the block and also with the old style exhaust stubs still fitted to the exhaust ports on the head.   
So what are your thoughts on using these?? Also can I use the F1 cam shaft on the earlier head set up or would I need an early K model cam.

Thanks for any thoughts or wisdom from your experiences.

You need a K6 set of barrels, head and cam. There is a member that had a F1 engine that I took some parts from, not sure if Mark CR750 still has it. Always worth a PM.

Yes I still have the F1 head and barrels, I don't have the cam though because that was one of the parts that Trigger bought.
