My ex-Popo Diplomat ran almost 105mph in the 1/4 w/a 750VS Holley on a DP4B intake, 284°/.484 PurpleShaft, stock 9.2:1 slugs, template ported closed chamber '516's I added the 1.75" exh. to, & mis-matched headers....in front of a 4-gear.
The bone stock '66 2bbl engine with a RR intake & iron logs, slightly larger 440 cam, & same 750VS ran 100mph with a 125hp NOS Holeshot kit, & a best of 94mph w/o the juice. I was working on a timing retard setup to get the most from the NOS but never got the chance to use it.
Upshot is, it's easy to do the math for 105 in the qtr., I was using shitty tires & leaving in 2nd gear at the time so.....really only interested in the mph#'s.
