Piston/Valve Clearance

Aubrey N Bruneau · 09-10-2011, 08:56 PM

Basically the same angles as a small block, Adger. My pushrod is a custom made heavy-wall Manton. Yes, they helped too. Rockers are BBC 1.7.
Intake and exhaust valves are same length, but you're absolutely right... those intakes are heavy !
Then again, if you saw the intake lobe on my cam, you'd wonder how it can run !
doh !
It really IS that crazy.
Looks like I finally do have it under control though. Didn't get out racing this year ( just closing the deal on our house, so after what we went through the last couple years, this has still been a good one ), but I DID get the valve train under control. Went out, took a few gears. My new tattle tale-tach "blew the wistle" on me, with a couple 7300+ RPM shifts
HEE HEE !
