Does anyone who has gone with the larger valves have any specs on them. My bro-in-law is a machinist,
mechanic (race motors) and has all of the equipment needed to do the work.

I just need to know the specs so he'll know what to order. I'm probably going to be doing some major upgrades to Yeller very soon.

Also, race cam specs, porting specs & old family recipes for barbecue sauce would be great!

Thanks,
SD

 

sam coe is another company that puts larger valves in he might be able to help you.
