Say a 399 lift stocker cam checks between 374 and 376 lift on each cyl with stock length push rods.
Then you put a longer push rod and can check 392 to 395 lift. (with no clearance problems)
How much performance gain would i expect et wise and hp gain if any ?
Best et is 12.18 in the 1/4 and 7.65 in the 1/8 mile.
