Just went and picked up a friend's 750 Double Pumper that came off of his Malibu Station wagon, with a 400 SB that ran 7.3 with this carb.
I'm gonna stick it on the Monte and see what she does, probably go back to the track with it soon.
The last time at the track, almost 2 months ago now I made it down to a 8.01@89MPH with one pass being 90MPH but a little slower et, this time I opened the Headers, still major bogging off the line.
Losing close to a second right there on the line. If this Carb works well, I'll take my 870 vaccum secondary(not a double pumper) and have it modified to be a Double Pumper.
Timing is LOCKED OUT at 36 Degrees. Also will be getting a line Lock real soon, and adding Electric Fans, and need to install my Drive shaft loops this week.
Then according to the ET it runs, may be looking at Roll Bars to be legal.
Lots to do, plenty of Time with summer off and Not enough Money!
