Got a 'phenolic spacer' on (spelling?) to keep heat out but clearance is TIGHT (like 1mm tight) to bonnet. It doesnt *quite* touch but its damn close.Dave999 wrote: ↑Tue Apr 20, 21 11:02 am PS if all else fails
4 hole spacer under carb
if that works then maybe....
stick this in your manifold

turns a race only manifold into something that works better on the street
i.e if you find a 4 hole spacer under the carb makes things better then this is the next step
better distribution at low RPM with only a small impact at higher RPM but obviously has an impact on WOT all out race operation in the 5000+ range where plenum size/space is king

Thats an interesting thing. Never heard of that.
