questions on my NA build-up...

[HondaFan81]

1) Are there any questions in terms of reliability with 0.020" overbore, forged pistons & 11:1 compression ratio setup on F22a1?

2) With 272 Delta camshaft regrind, resurfaced (no milling) cylinder head w/P&P, upgraded valve springs, 11:1 Wiseco pistons, stock valves & rest of valvetrain components, new stock headgasket...

Will I have any piston-to-valve clearance probs? Will I have full use of my Skunk 2 cam gear?

clay the motor during the build to find out...

I personally would be leery of just going on someone else's say-so...they aren't going to pay the bill if your valves kiss the pistons or each other...every motor is different...

Although, having said that... I am going to install my adj cam gear probably next weekend along with some other goodies... I'll let you know if I run into any problems if you like...

but regardless of what I say... If I were you, I'd still clay the motor just to be sure...

but if you check out 93Accord's motor build sticky on AT he clayed his motor with a slightly less aggressive cam (and although I cannot get any info on the particular JG grind he got, going by the grind number on it and comparing that part # against other cams with the same part # for civics & tegs, etc. it should be around .400 of lift[similar to the Delta 260]) and he had ZERO interference with the gears fully advanced and retarded....I believe he also did so without a HG in place which would give you additional clearance...

although I can't imagine for the life of me why someone would fully advance/retard their cam...

Supposedly advancing your cam you can get more top-end power and if you retard it, more low to mid range power. But then after doing this, you'll have to reset your ignition timing supposedly.

This is what Delta Camshaft states in their website. I plan on setting it to stock spec, then playing with advancing/retarding it a bit to see what's up. I assume just having the regrind in itself at stock cam timing setting will reak high RPM power in itself...if anything I may retard it a bit.
