Well my motor is on its way and the company that built it is very reputable and builds nothing but performance engines and has been in buiness for dam near 30 years. So after talking to various other customers and such I bought their 7.0L aluminum 427 engine with mahle -4cc forged pistons, 1.5mm powerpac ring set, callies rods, eagle crank, new GM 7.0L block, clevite H bearings durabond cam bearings, arp 2000 rod bolts, arp mains, and arp head studs. Very nice price and has a warrentee to boot. I am gunna HP tune it with 1 bar speed density, 42 pound injectors and single 340 walbro pump. I am gunna be using AFR 225 heads upgraded springs and 72cc chambers with GM MLS gaskets, LS6 intake, 1 7/8s headers probably kooks this time around, true dual exhaust, 4L60e for now then up too a built 4L65E im installing a 3200 stall, it has a moser 9in with 3.42 gears, and upgraded 1200 hp drivehaft. When i ordered the engine I asked about cams and he asked is it daily driven and I said yes, and I do take it too the track about 2-3 time sa month. I will also be spraying a 150 shot later when its broken in is what I told him. He said hes had alot of luck with an isky grind and so since hes used it alot in his engines I ordered it it got here today and the specs are 232 at 50 intake, 242 at 50 exhaust, 113 lobe sep but its only got 528 intake lift and 538 exhaust lift, I was originally looking at katechs street attack cam with 220intake and 240 ex but theirs has just over 600 lift. the springs in my heads are the upgraded AFR springs and their good too just over 600 I think but better seat pressure. I dont plan on reving any higher than 6800rpms max but will probably not even go that high. It looks like a nice cam and all but wondering what the experts here think. I know lift is not everything but just seemed low to me. duration looked pretty good I guess I could always add 1.8 rockers to it to up the lift or will this be good??? thanks for any and all help

 

The Katech cam is designed for LS7 heads. It would not be optimal for your heads at all.

I really can't comment on the other cam other than if this guy had been using it and he is as experienced as you say, trusting him may not be a bad idea.

 

the one cam is short on lift. Too short.
