Back in late 60s built a 53 ford with a flathead 20 over mild cam 4v off 56 ford 292ci, 3 on the tree, stock rear, I think it was around a 3.70 not sure. Put some short 14" tires on it. It ran in the mid to upper 15 sec. 1/4 mile never checked the hp. But it broke a lot of trans., rears, & axles. We ran out of junk yards with spare parts for a 53!!!!!!!!!!! So my buddy retired it from the strip.------------------

you are limited in cubes to not much over 300, breathing isn't fantastic and they won't take much cam. Getting over 300hp would be doing good.[This message has been edited by TomP (edited 02-03-2004).]

My dad owned a pair of '40 Ford dirt cars around '65 to '70, racing on a quarter-mile clay oval (Coweta County Raceway in Newnan, Ga.) The rules in our class (the "Hobby" class) were cars from 1937-1954 running those year's V-8's (if they came with them) or new sixes. All cars would get out after the track was watered down to "iron it out". After the track surface was ready, the guys would start getting racy (and sometimes got REAL serious about it). One incident stands out. A '55 Chevy with a hot 327, a '56 Ford with a 289 (both consistent winners in the Sportsman class), and our best '40 with a 280+ cube Flathead hooked up and got to racing. The three cars were so evenly matched that they ran for fifteen laps, nose to tail, with nobody able to pass. The drivers had a great time! Another incident was when it looked like the show was going to be rained out. lots of cars left, but the weather cleared. They had to combine the Sportsman and Hobby classes to make a field of twenty cars. We finished third; first Hobby car beating seven Sportsman cars. I LOVE Flatheads!

Im going to have to go with the Vortech blown, reverse flow, 301 inch flathead in the Flatfire Streamliner that I saw go 305 last year at Bonneville. They claim 700 hp @ 6000 rpm with 18 lbs boost. An Ardun head flathead is an overhead. Flatfire is a true flathead but probably the worlds most expensive one.

Ardun heads were designed by Duntov but they were unreliable and didnt make any power. He sold them to C&T Automotive who made them fly and stay together going over 300 in the early 50's. The original pushrods were cast steel & weighed as much as a connecting rod, valves were too heavy,Buick lifers galled,& head gaskets blew all the time, & the intake & exhaust manifolds were no good.
