on a big block Chevy.. or anything, any bits of wisdom? I'm about to start reassembly, Tore the carbs down cleaned em up nice, they look almost unused, got all the original linkage, and stuff. would be nice to avoid a whole lot of trial and error. Going on a semi serious 454 with early open chamber aluminum rectangle heads with big valves and lots of port work done, Comp Cams Extreme Energy cam, aprox. 9.5:1 compression, B&M T400, 2500 stall, 2000# car, hot but not too wild.

Got any pics? Sounds like an awsome motor, does it use a center bell crank or two sets of progressive linkages? -Jesse
I'll post some fresh ones in a day or three when it's all together.. I know there must be someone on here who's running at least a small chevy setup. where's Milner? he used to have the fastest car in the valley.. Paul
Some copies of old Man-a-fre info on e-bay for ya... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=6762&item=2432831350 Might be of some use to you???
Paul... you might consider e mailing C9. I remember him mentioning them in his book. He might remember some info from his days at the track.
those articles on ebay are only $7.00 "buy-it-now" price.sounds like a bargain to me,especially if you don't have anything else to go on.
I tried to run a Man a Fre on the street in the mid 70's. People don't like my response because is not glowing. Mine was a small block with the direct injection option. 62 Corvette 350 4spd. After new carb kits it took several hours to balance the carbs. I got it all dialed in. Cold starts were no problem with 4 accel. pumps working in unison. Idled beautifully. Drivability on the street was a PITA. It would fry the hides in a heart beat. That was the problem. The go pedal had such a hair trigger coming off idle that it wasn't fun to drive. I'm talking real world driving with other people on the street with you. You had to be sooooo careful leaving a light. Mine was a 4spd. Too little and it stalled. Too much and you're smoking the clutch or the tires while running up the ass of the guy in front of you. The car was just no fun to opperate on the street. It's almost impossible to opperate smoothly in the real world. It was made for drag racing. Throttle response was fantastic. Banzai starts were fun, but how many times can you get away with that? People don't like to hear this. It ruins the fantasy. There is a reason that they are few and far between. My cars need to be fun to drive and not a PITA. Just my personal experience.
Howell made a spiral plate to wrap throttle cable around on Holley TBI as all 900 CFM opened at once. This varied the radius so part throttle would not be as touchy. Could be the answer for setups like this.
Fat Hack, Yorgatron, I got 'em, I sent the guy an email asking for a total and they were in my mailbox before I could stuff a ten spot in an envelope! very basic info, but useful. Tommy, I have no doubt you are right. I just have to try it though. Paul

I think if you look back in some of the old magazines, you will find that in the few small adds that Man-A-Fre ran, the ad copy was aimed at hard core road racers. I don't think they ever thought that many people would try using the on the street, as they considered it a race manifold. But I have seen guys using them in street driven cars and a couple of them told me they figured a way to make the drive-abilty OK for the street.
