All of them/any of them. Clearance at the firewall is the most likely issue. It may need some tweeking
Also an HEI needs a circuit that doesn't have a resistor wire and it should be at least a 12 gauge feed wire.

grab one of these and you will not have to mess with the firewall.

On the off chance you're using a Tri Power, the big cap HEI has clearance probs w/it. Don't neglect to set up whatever distributor you use w/a performance advance curve.

To be the "nay-sayer" here must point out, while Lynn is mostly correct, the HEI from the '81 models of 265 and 301 will NOT "work" as they have a computer interface the earlier versions don't have.

In the '66, firewall shouldn't be a problem, in either the A- or B-body. Heed cobalt327's statement about TrPower... Same is true of the old Edelbrock P4-B and it's "knock offs" (Weiand, Offy, etc., older dual planes). Performer and RPM have no clearance issues with HEI.

Hee Hee...I stand corrected. LOL
Actually I think they will fit, but as mentioned the CCC setup wont run, unless you perform the bypass on the computer circuit part of the module . And then it wont have any timing control due to the lack of a computer and sensors to accommodate any timing control.
Pretty much not useful for much...
