I got word today that next year Top stock is out.. will not have a class or index. I wouldn't build anything for Top Stock rules. Could end up being a waste of time and money.

Danny, are EFI allowed in crate motor, like a 1991 Ford Mustang with the Ford 340HP/E cam crate motor with EFI?

Thanks, Tom Sr.

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.

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).
