It's just that some blocks have a brass resitrictor pressed into one particular orfice, and the other metering blocks have the restrictor pressed into a different orfice. The both orfices exist in both metering blocks - it's an easy thing to miss. I'll troll the net and see if I can find a picture for you since no one else posted one.

Whats size is the existing IFR and what size wire did you put in it? That would be helpful to know. About a month ago I wideband tuned a 750 vac secondary in street 351C in a Mustang. About the same size engine as yours, similar camshaft, same size carb. That combo ended up with a .032" IFR and a .075 IAB. I'm guessing that would be a good place to start in your case. If your IFRs are much bigger than that, you'll need the appropriate sized wire to make it close to the equivalet of that (just as a starting point). Jim Last edited by JimG; 09/03/09 06:17 PM.

Snort! You didn't have to admit that, ya know! Ask me about the time about 20 years ago when I put a 440 intake manifold on backwards. Yes, it will bolt up!

I left the sight up at work and a fellow coworker decided to be funny. Yes I did have the jets backwards.
