Huffaker 4 bbl. intake FWIW.
For the record, ports measure 1.0-1.07" wide x 1.700" tall, not runner ported, just matched to ported TR8 head. Overall height 3.75" front of carb base and 4.0" rear, without carb adapter. This manifold added 3-4 cfm. airflow to head flow. Good Luck, roverman.

Re: Huffaker 4 bbl. intake FWIW.
Art,
Good info on Huffaker manifold. It is now in my new 3 ring binder for the RV8 - the one that Bill Young reminded me to put together and add to after each race. Stuff like this info sure makes it easier - days/weeks/months later - to make decisions for changes. Thank you. phillip g |

> For the record, ports measure 1.0-1.07" wide x 1.700" tall,
> not runner ported, just matched to ported TR8 head. For my unported Huffaker, I got 1" wide by 1.75" tall, the same as a Buick 300 or GM 215 race head. The short runners measured 2.6875" long and the long runners were 4.375" for an average 3.53125" length (required input for Dynomation simulations). By "matched to ported TR8 head" do you mean a factory TR8 head or to your ported aftermarket Merlin heads? > This manifold added 3-4 cfm. airflow to head flow. That's often the case with a bare single plane intake manifold. You'll likely see a decrease with a Holley carb body in place. We did when we tested the Huffaker and Willpower with a Holley carb body (throttle plates wired open) in place. Dan Jones |

Re: Huffaker 4 bbl. intake FWIW.
Dan and clan, Huffaker ported TR 8 heads,( came with the GT1 car). Ported Merlin's measure 1.0" x 1.80". Dan I'm not sure what dim. we used for average runner length/ Dynomation, for my cam selection. I'm wondering how to "sqeeze" 830 cfm. anything, onto Huffaker opening ?Thanks, roverman.
