Anybody know what adapter plate for the vortex 4.3 to Rochester 2 barrel is or a part number ? thx
Check around for a few marina's to see if they have any old 4.3's laying around. Cast iron single plane spreadbore intake. Also on the trans for the auto's it's the 700r4/4l60/4l60e I bolted a 350th to mine used the factory l even used the 4l60e flexplate.
I have a 1992 4.3 with 2003 Vortec Heads. Would this cause a hesitation with power with the Vortec head on a non Vortec block? I've ran this motor in two shows already and in both it always dies in gear but only when you floor the gas pedal. I have to tether the pedal to get it to not die and keep pressure when i shift into reverse or drive or else it also dies. But in nuteral and park it revs with no problem, even flooring the gas pedal. Any other ideas on what it could be before i go and find a set of 1992 Heads to clean and polish up to throw on for next season?
