Anyone know if GM injector pods can be installed in Holley TBs? There are a bunch of Holley TBs out there on Ebay (2” throttle bores) but to get a 2” bore in a GM TB requires a not-too-common 454 TB.

Holleys also have Holley-specific parts and injectors.

So could a guy take a Holley TB and install GM parts and get the best of both words? From the pics I’ve seen it looks like a reasonable proposition.

Thanks for the reply.

I'm wanting to swap the whole injector/regulator/fuel fitting assembly into a Holley, not just the injectors themselves. The GM type is super-cheap and super-common, probably more reliable than teh Holley stuff.

The GM TBI injectors won't work in the Holley TBI, though Chrysler TBI injectors *might*. See this: http://www.megamanual.com/v22manual/minj.htm#size

I wouldn't be surprised if the Chrysler injectors are a direct drop in. Holley built the Chrysler TBIs and the Pro-Jection looks like they had retooled them into an aftermarket unit.
