360 LA installing Promaxx Aluminum heads

Well allrighty... lesson learned. I forgot to subtract the depth of the cup on the measurement tool to get the effective length. After a few trips to Summit.. H/T to their counter folks.. really helpful.

Anyway... quick math says I need a pushrod 7.100 long in a ball and cup. Interwebby says no such animal exists.. if I wanted ball/ball the world would be my oyster as there is a large number made in that configuration.

Anyway.. if anyone knows where I can lay hands on an already made 7.100 ball cup please cluebat me in. Otherwise I'll need to order Monday and wait up to 3 weeks. .
