Anyone ever had one on a dyno. I kinda always heard establishments on 300hp. But I don't think they were anywhere near that. For Wall they were 258 max, no head porting, and a 1bbl carb. Everyone ran the big early Rochester carb. NES and Atlantic City could run 2bbl carbs and Im sure some more stuff. Islip figure 8 cars were similar. 

Not familiar with the class, what 6 cylinder motor are we talking about? Chevy 250/292 or Ford 300? I have a street rod pickup with a heavly worked over 292 that made 300hp on the dyno. Not sure if what I had done on my 292 would have passed tech in the class your referring to though.

It was Chev, Ford and Mopar. With an occasional AMC. Max 258 ci, I believe. 

A 1967 6 cylinder Camaro says 150hp on the air cleaner. 
TV shows like Engine Masters have all built highly modified 292,300 and slant six'es. Most of them were below 300hp. 

They ranged 275 to 300.  250 Chevy straight six. A 190 cid Chevy head increased the compression. A cheap header and you had what you had.  Stock ignition with a coil  

Bernie Bailey had a good Charlie Weston engine.  Charlie took a four barrell Holley  and machined it down to a single barrel carb. A real work of art that was legal by rules but the track banned it. Donnie Chambers used a stock type clutch by the rules but it was stock in a Honda.  That got him a one year suspension.  Back than anything cheated got you a one year suspension. No messing around. 

Hey Kenvin, tell Bernie I want that carb to put on one of my VW's. I'm getting a chopped roof one. 

That thing was super trick. It's still around

-YEAH, KEV !! TOM O'RORKE WAS KING !!!

thanks for the post, john--

chevies when we started the division were 230ci or 250ci

fords were 240 ( seperate manifolds) or 240ci (log manifold) 

plymouths and dodges were(225ci slant 6 's)

my engine was a 250ci punched .040 over --built by Ron Buck-

he didn't want to go more than .040 because of the close water jackets--

do you know what the overbore was on your dad's & uncle's engines were ??

blessings !!

I don't remember what the overbore was. The last few years my Father ran a Weston motor. It had aluminum rods. His early engines were just cam swaps on a good junker or rebuilt engine. Not much more. I remember Richie Beridino(sp) said he had a rebuilt engine with a JC Whitney cam. That was in like the first full seas of moderns. I just think the induction help back a lot of HP.
