Just measuring the pushrods for my 440 - they seem REALLY long.
Build:
'70 440 decked .010
Icon FHR pistons .060 over (about 10.4 to 1 by my calc)
Comp cams Hydraulic flat tappett .545/.545 .247/.241
Hughes 1.6 adjustable roller rockers (makes cam .581 lift)
Trick Flow 270 Heads
at 0 lash the length (with 2 threads of rocker adjuster screw showing, using check springs on head) is 9.625" (this is total length, not effective length since cup on rocker end of pushrod).
Has anyone run the Trick Flow heads on and RB and what did you see for the pushrod length? Have I lost my mind (that's already a yes BTW)?
Will be ordering pushrods shortly - what wall thickness? What can the TF heads handle from a diameter standpoint? Leaning towards the 3/8 dimeter, .095 wall thickness.
The rockers set up nearly perfectly in the middle of the valvestem and don't move much. I'd say maybe a tick towards the exhaust on the valve stem, not gonna chase that.
Any help very appreciated.
