NO.....Carbs only ! 750 CFM for small blocks and 850 CFM for big blocks.

Re: IHRA crate motor question about intakes....
 

Yea, what Terry said.
A particular crate engine first has to be "approved" and put on the accepted list by IHRA to be legal for CM. Just because a factory has a combo available doesn't make it legal. There are versions coming out every year so keeping track of specs would be a nightmare. The factory normally has to provide the specs. For simplicity, it's been 750/850 carbs and any unmodified, commonly available over-the-counter intake that fits under the OEM hood. (Measure your 1" spacers. Some are a bit more than the 1" advertised.)

Thanks to both of you.

Re: IHRA crate motor question about intakes....
 

1 inch spacer includes the gaskets also.

Top Stock was just a hiding place for some A/SA cars that were slow anyway.

Saw one drop out and re enter to avoid a headsup once.

The spacer/adapter is measured by itself. Gaskets NOT included. 1 inch max. (1.000).

Re: IHRA crate motor question about intakes....

As usual who ever did it was WRONG. Or didnt care unless Baker changed the rule after I left..

Re: IHRA crate motor question about intakes....
 

Sure your not mixing it up with head gaskets/deck height?

Gee, for a box/.5 tree racer, you sure are interested in CM Stock.........................again?:p

Re: IHRA crate motor question about intakes....
 

Might be confused with the engine Masters rules. The spacer IS measured with gaskets at EMC.

Guys I'm not stupid. My car got torn down as much as anybody the few years I was in stock.
Carb spacer and gaskets.
