Cotton Perry's H/MP #2352 Chevy II(s)
 

Am I reading correctly that the Headrick engine used THREE four-barrel Holley #4210 carburetors?

Where did you read that?

I saw under the hood of the pocket rocket at the 1976 race at Miami Hollywood Speedway Park.

There was three two barrels, possibly three webbers or three Holleys
cut in half.

I don't know what they were but there were 3 four barrel carburetors at one time.

Looks like an old article from PHR magazine:

I saw it once with what appeared to be three Weber 55 WDCOE carburetors, and once with what appeared to be three 500 cfm Holley two barrel carburetors. I never saw it with Holley 4 barrel carburetors, but that does not mean they did not try it.

There were at least three Perry-Headrick #2352 H/MP Chevy II cars- the red '62-'65 car, the white '66-'67 car, and then the red '67 car that everybody remembers.

And they were constantly trying new stuff, so there were probably countless variations of those three cars.

Near as I can tell, the #4210 was a 585cfm 4150 originally used as the OEM carbs on the cross-ram intake for the Chevrolet 302 V8.

I think some of the stuff they did was to try to collect more contingency money- I don't think Weber was paying contingency money in Modified Eliminator in the '70s, so if they could figure out how to make it run the numbers with Holley carbs, they could make more money.

They had the same issue with intake manifolds, and if memory serves, they used to run completely hand-fabricated custom intake manifolds, with Edelbrock logos attached to them, in order to get paid.

I worked tech in Div. ll 1970-75 and don't remember 3x4 carbs on the car or any MP car. Rules were 2x4 or 3x2 in modified. Did notice something I didn't remember in the 1976 rulebook. It stated that on 1/1/77 modified production classes will be consolidated with the gas classes but In don't think that ever happened.
