I have already acquired the distributor, coil, wiring harness, etc. from an '84 parts truck, only to discover that it is computer controlled. I understand the earlier version through '83 uses a different system including a separate ignition box. Does anyone have any experience or recommendations for either the 72-83 earlier version or the '84 & later version with the computer. Any performance advantages to either? How difficult is the '66 retrofit using the computerized ignition system. My preference would be to use the later version since I already have the component parts except for the computer. Also, the under-hood appearance is cleaner with less clutter, without the ignition box. In case you were wondering, the engine was recently rebuilt with a 294 degree Crane cam, ceramic coated Clifford intake/headers, and a 500 cfm Carter AFB-4V. The engine compartment has been cleaned up, repainted and detailed close to show conditon. The stepside exterior is totally original, a little tired - so it makes for a good sleeper. It runs great already, but I'm hoping the ignition conversion will give it a little extra uumph and dependability. I realize most of you guys routinely trash the old six shooter in favor of a big block V8, but I have been pleasantly surprised at the performance of this old "stump puller", an affectionate term used by Carolina dirt track racers in the sixties. The best part is the look of surprise when the hood is raised. I would like to hear from anyone interested in in-line sixes with information to share or questions.

I have a 3 year old Holly 4160 (80457) 600CFM, electric choke, stock jets, 31 squirter, standard secondary spring, sittin on a 1970 351W (Performer 351W manifold, mild RV cam), duel exhaust (69 Mach I cast iron manifolds, 2.25" exhaust all the way to the back).. this is all running thru a 1976 C4 into 3.25 rear gears... this is all in a '64 F100 shortbox. Tire size in the rear, P235/75 15" (basically a daily driver)... Set the idle mixture using a vacuum gage, get 18.5lbs at idle (albeit with a very slight fluctuation in idle +-50rpm).. Engine has about 65K on it, doesn't burn any oil, double roller timing chain with no noticable slack.. What is this leading to you ask... Gas milage sucks.. 8.5MPG if I even think about getting in the secondaries, 9.8 babying it.. is this what I can expect... if so, that is ok, the truck is a blast to drive, if not, any ideas on what I can do (other than changing rear gear ratios) to improve the milage?? Thanks, Bill in Texas '64 F100 Shortbox (351W/C4) _________________________________________________________ Do You Yahoo!? == FTE: Uns*bscribe and posting info http://www.ford-trucks.com/faq.html ------------------------------ Date: Fri, 18 Jun 1999 15:10:52 -0500 From: "Baldwin, Dave (CPCP Design)" Subject: RE: FTE Perf - Gas Milage and Holleys Bill, I've never had a 351W, but I had this carb on a larger engine and got over 20MPG--but it wasn't a truck (weighed as much as one though). Rear end ratio was lower (numerically), so that may have been a factor, but I don't think it would've made the difference between 20 and 8.5 MPG. If it's running right, this is puzzling. How is your milage being measured? Could it be that you're driving different rear gears than the C4 was originally driving, so your odometer is reporting fewer miles driven than you are actually driving? It seems that you should be getting twice the milage that you are. You could get an EGO sensor and see if you are running way rich--or find a shop that could test it for you.

I'd guess you're running a rich mixture if that's a stock carb on a 351, and if you're not right at sea level then altitude adjustments might also be neccesary FYI: I just bought the same carb and when I removed the primary float bowl to change the PV and main jets, I found a deffective main jet!

No it doesn't . This book is what most parts counter people would have in their "catalogue rack" for them to be able to order indivdual parts for Holley carbs. It does however have a Holley part #. So theoretically you could order one from a Holley dealer. Part #36-51-7 Illustrated parts and Specs. My book is about ten years old now so the suffix on the part # may have changed.
