best distributor for the buck

Be careful of the 45 buck HEI unit. They have a bastard Bosch module that's only compatible with Holdens in Australia.
I popped the lid on mine and saw a 4-pin ECU w/ spade connectors. Different than the GM 4-pin module but looks like you could easily swap one in. In fact, when I ever get around to using that distributor, I will likely put an 8-pin HEI under the cover (w/ cut-outs) since those allow spark timing control.

So if Johnny's car beats an HEI sparked car in a 1/4 mile would that prove that the Mopar ECU is superior? Infallible logic. At least Johnny's dad can't beat up my deceased dad.
