Alright so, got cam questions. Motor I’m buulding currently has CNC ported NPI heads, 3cc pistons from an Aviator motor, Edelbrock intake manifold, MHS .550” lift springs, and Crower 0.060” offset retainers. I wont be revving this much higher than about 6500rpm. I was going to do either MHS Gen 2 2V Stage 2 Na cams or the MHS 5.4 2V Stage 2.5 cams, but I was offered a set of HiTech Stage 2 cams for stupid cheap (less than buying new PI cams kinda cheap). HiTechs are 234/230@0.050”, 111LSA, 0.545/0.495 lift on a 112 centerline, was thinking about timing them more around the 108-110 if I did them. The MHS 5.4 cams are 228/226@0.050”, 108 LSA, 0.550/0.500 lift on a 106 centerline, while the MHS Gen 2 2V cams are 224/226@0.050”, 111.5LSA, 0.550/0.530 lift on a 110 centerline. These also would potentially get bumped to a 108 centerline to take full advantage of the NPI’s extra clearance. I honestly dont know which cam would work best for my build out of those three given that I dont want all my gains to be in the top end, would love some advice.

Do it once, do it right. Call a cam grinder and get custom cams.

I agree
Sounds like you have some money in the motor
Buy some nice cams for it

That’s about 6 months of trolling Facebook and forums for deals tbh, cams would be the only thing I’m considering buying new other than the obvious (rings, gaskets, etc) but even then I’m on a college budget. While custom grinds would be nice they’re still a good bit more than I was hoping to spend.

Budget you say?
Then run the cams you can get cheap
The 112 centerline sounds like ones I would run anyway

CMS stage 2.5 cams is my recommendation.... .550"/.560" lift, 230/236 .050 duration, 109 LSA I would check to ensure they fit with the NPI heads but believe they will... the flow rate for those heads is way below 75% so you will need a dual plane cam.... hence the larger lift on the exhaust valve to work properly with those heads.... or a custom grind similar to this if with a little less duration if there is PTV issues... I don't believe there will be but call Cushman motorsports...
