63=64 and Head question
I was dissapointed when I tried match my plenum to the TB, I have a 63MM DRM TB, and noticed that they did not port match the intake, it was 60MM. So I opened up the intake to 63MM. Dominic came over today so before he got here I matched up TB to the intake and there was still a difference. After remeasuring the intake, I measured the TB again....difference is the TB is actually 64MM.
Also Dominic and I noticed that the head surface at the IH was machined right at the lip, just slightly. Is this from the factory, I would assume so. LGAFF 92 ZR1 #234 |

Re: 63=64 and Head question
I happened to bring my 63mm TB to Lee's place and it also measured 64mm. Hopefully, 2 more plenum runners and the TB opening finishes off my manifold/IH porting project. Next, its the cylinder head match.
