Valve-Piston distance
Just got my SB heads back from the shop.
new valves all over. increased to 2.02 intake valves.
planed 1mm (about 0.40")
my camshaft:
Summit Racing Part Number CCA-CL20-225-4
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. lift
Lobe Separation (degrees) 110
I have mopar performace dish pistons. Deck hight about 3mm, dish about
1,2mm.
You can`t see it at the pictures, but the intake valve is actually a little bit closer to the piston than the planed surfaces.
Anyone who has excperience with similar setups?
Will I have a problem with too small distance between valves and pistons?
