Re: 350 piston ht.

Since its not stock you need to figure what pistons you have and their compression height. Centerline from the crank to deck height is 9.025

350 aftermarket pistons vary widely, and can change:

345np030 - 1.54 compression height
H859cp030-1.435 compression height

.105 difference!!
