P&M industries full flow kits are badly made MCF knock offs. I have built over 30 engines using the proper MCF full flow kits brought from Phil Goller (Goller Hot Rods) who is the only supplier of the true MCF kits (still works with Mark Kirby on occasions) and other MCF parts. The proper kits are fantastic.
I had one customer who brought his own kit for an engine i was building lasted a whole 25 miles before the internal braid line blew apart, this is when i found it he had brought the kit from PM industries, he new better the second time.
