X block sonic test

MerlinsMopar said

A lot of power is made in the heads and cam. I built a 318, .030 over with ported x heads and a nice cam. 4 speed car. 73 cuda and I smoked my buddies 70 camaro with a built 350 and 4 speed. 4.040 is stock 340 bore if thats what you measured it at. I loved being able to say, yea its just a 318 in there. Lol.

I have some w5 heads I’ve got as far as I’m comfortable going on the port work, and no holes yet. My machinist said let’s sonic test them.
I have some w2 heads that are done on another engine, I’ve not flow tested but are pretty maxed under the valve, with 2.08 intakes. Paccalloy springs, ti retainers, Strip dominator intake, and a M1 for the w5 heads.
