race veterans plz help!!!!!!!

I would also say carb probs.
I would try to borrow one to try it out.

My first Holley was an old 850 double pumper.
I put it on my 440 with a 509 can.
Took a few evenings to sort out someone elses mess.
Had to change the pumps and ramp speed for the secondaries.
Then of course the squirters and jets.

I left the tree from idle and not bog.
I know many people think it is crazy when I tell them, but when they see me leave the line, they believe.
