Ok, dont flame or just reply saying they are chinese junk, ive been reading alot of threads on them and seems to me its about 50/50. The majority of folks running them without issues bought them bare, as the parts they use to assemble seem to be junk.
I can get a set of these in a 300cc oval port with 119cc chambers for 640 a pair shipped. I was looking at doing bigger valves and some minor port work running about 900 total after parts and machine work. These procomps will still flow better than my reworked vortec heads(if you believe the published flow numbers) and will def shave some weight. I already have a complete comp cams spring kit with 925 springs that i plan to put in them along with some manley stainless steel valves, and a set of Lunati 1.7 roller rockers, i know ill need custom length pushrods.
Id like to see if anyone here has any experience with them on a jet boat application, and would be better off with my reworked vortec heads or giving the procomps a shot?
I'm working on finalizing the build for my 427, and the head i run will determine the piston, flat tops with the vortecs and some small domes with the procomps, also, im looking at running 9.0:1 with the iron vortecs and 10:1 with the aluminum heads. I know with the edelbrock EFI intake and the Procharger making power wont be an issue with either head, mainly going for the weight savings and making the same power on less boost so it will keep it more reliable. Also my cam will be a Lunati, 238/248 dur@.050 .600/.600 lift on a 112 LSA, just not sure if i want to stay hydraulic roller or make the jump to solid roller, i know the power advantages, but don't want to be running the valves every trip out, but maybe its not as bad with these modern engine parts and im stuck in the old school way of thinking?
Anyways, thanks as always for the help.
