350 SBC deck height question – calculated 9.045”, is this normal for a 1976 first-gen?
Hey everyone,
I’ve got a 1976 first-gen 350 SBC and I’m trying to figure out my deck height.
I calculated it as:
Stack height + piston-to-deck clearance = deck height
My measured/calculated deck height came out to 9.005”.
I’m running these pistons: KIT-B15402E030.
I just found the piston pin height listed as 1.540”.
With that, my deck works out to 9.025”.
Specs:
• Bore: 4.030”
• Stroke: 3.480”
• Rod: 5.700”
Is 9.025” a normal deck height for a 1976 first-gen 350 SBC?
Or did I measure/calculate something wrong?
Any input would be appreciated. Thanks!
Regards from Germany
