Hi,

Im putting together a stock STROKE 440 and im using KB forged pistons on it. I decided to go with a looser sidewall clearance because I do intend to drag race it every now and then, but it will also be used on the street.

It has stealth heads, 10,5:1 compression
floating pins
performer RPM intake


and this cam:
Summit Racing Part Number CCA-CL21-225-4
UPC 36584046738

Cam Style Hydraulic flat tappet
Basic Operating RPM Range 2,300-6,500
Intake Duration at 050 inch Lift 240
Exhaust Duration at 050 inch Lift 246
Duration at 050 inch Lift 240 int./246 exh.
Advertised Intake Duration 284
Advertised Exhaust Duration 296
Advertised Duration 284 int./296 exh.
Intake Valve Lift with Factory Rocker Arm Ratio 0.507 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio 0.510 in.
Valve Lift with Factory Rocker Arm Ratio 0.507 int./0.510 exh.
Lobe Separation (degrees) 110


I went with ,0070"

Will this cause premature wear, or is it only that it will be noisy on startup but wear is not really an issue?
