What custom grind would be good? Grrrr, now i'm thinking custom grind.
I have stock heads, i might get the ported, but not for a while. I have bolts one like LT headers, exhaust lid, ported MAF, etc. Its a daily driven (not in stop and go traffic though) M6. Also, it will have 4.10 gears.
I was thinking the 230/224 111LSA, but a sponsor is having a GP on comp cams, and i am thinking about a custom grind.
What should i go with that will give me the most HP out of stock heads? I remember hearing the stock heads stall out around .500 or .550 so i assume i want to just touch that number lift with the cam. What about duration, i am going to be N/A so should i go split reverse? I want a bump idle, the 111LSA appealed to me with that, also won't the lower LSA bring the power band lower?
What would be the ideal grind for me?

Re: What custom grind would be good? You could have Comp duplicate a 230/224 if you wished. Or a 228/224 or a 230/226 or a single pattern 226 or whatever. I'd keep the lift around the .550-.560 range.
Do you have emissions testing where you are at?

Re: What custom grind would be good? I have emission testing, i'm just going to swap in the stock cam for it.
I know i can have comp cams duplicate, but i may as well get a cam that will work perfectly with my heads and all if i am going with a custom grind.
What split do you think is best on stock heads, the 230/224 or 228/224 or 230/226? I think the 230/226 might be too much for a stock displacement engine with stock heads, the 228/224 might not be bad, but i think the 230/224 would work just as well.
What lift would i go with? Would i want like .600 or so on the intake, and what on the exhaust?
What LSA should i go with, 111LSA? I want the lope, and other things the lower LSA come with.

Re: What custom grind would be good? .600 lift might be too high. You might have some piston to valve clearnce with that. I am currently running a 227/224 with a .569/.561 on a 114 and it sounds down right evil. All my freinds call me NHRA cause how beastly this thing sounds.
