Anyone have an original 69 L/78 with THM400 ?

Bill,

Are you absolutely sure about the 4346 Holleys being used
on the ZL-1's? I've never heard that before. Also, why
would the ZL-1 Camaros get 4346's and the two Corvettes
get the 4296's? I would expect that a 750 cfm single
pumper ( 4346 ) would be severly under jetted for a ZL-1.
I know the L-88's got the 4296's as well. And the ZL-1
nudged a little more power out than the L-88, didn't it?

Your theory on the special ducted hood is interesting.

Just a fast question for you on that topic if you don't
mind. I believe all ZL-1's came standard with the ZL/2
induction system - correct? Back in the day, for serious
racing, wouldn't the second thing done to the car be to
remove the ZL/2 induction setup and put on a monster scoop?
Headers had to be first, then followed my a bigger-bader
Holley.

Why would Chevrolet go through all the trouble to build the
ZL-1's and then put a 750 single pumper Holley on it? It
just doesn't seem to make sense.

I'd like to keep this topic going. This development was
not one I expected.

Lastly, as you have indicated, the lack of use of the idle
stop solenoids on the ZL-1's would make sense from another
perspective. I don't think that Chevrolet expected any
ZL-1's to be cruisers - did they? Idling probably wasn't
too big a concern for these cars - huh?
