Ok guys. I'm about to change up my 340 significantly to the below specs and have 2 pumps available to me to replace my stock OEM pump. Keep in mind stock tank/lines etc.
-Summit 80gph
-Carter M6270 120gph (strip version)
Thinking the Summit may not be enough and the Carter too much. Probably the street version 120gph M6902 Carter would be best?
Whats a factory pump gph rating anyway..?
Combo will soon be:
340 bored .030 over
11.1 compression domed pistons
Ported X heads w/ 5 angle valve job etc...
Purple 292/.508 cam
Air - Gap intake w/ fresh 650 double pumper
MSD billet dist. w/ Mallory 6AL ignition
