Pushrod Length Question

[80fbody]

I'm measuring for pushrods on my 470 build with solid lifter cam. I've taken the measurement with checking pushrod at approx zero lash with two threads showing on the Harland Sharp rockers. Should I reduce the pushrod size to account for lash. I think the card is around .018" hot. How does that transfer to cold?

I would adjust the lash at .014 and then take the measurement that should get you close.

I have 9 inch overall length pushrod with plenty of adjustability. I ran them with my trickflows untouched and after taking .080 off of the deck surface. There was enough thread to still meet harland sharps minimum requirements.
I used smith brothers 3/8th .
You should give them a call though.
They're a great company and very helpful.
Clarification.

Mine were 9.90 from Smith Brothers on trickflow 240 heads.

I better go remeasure them. Yep 9.00, I recall thinking they were a bit short before I surfaced the heads.

I think we have measurement from a B block and an RB block here.

Mine came out to 8.125" for lowdeck with Edelbrock RPM heads, solid lifters & HS rockers. That measurement is to bottom of cup.
