Important if you run D-H/S or SA

I guess nothing NHRA tech does surprises me anymore. I see aftermarket alum. heads allowed with hp. lowered not added. Look at engines with 71 hp taken off. Engines with alum. heads and larger carbs that sure as hell was never made. I don't know when it will ever end. NHRA feeds us sh#t and we keep on eating. Rick.

The LD340 is on the 1971 blueprint specs, but not the 1972 340.

I need to submit one of my W2 heads that I was told was factory installed on the "Tunnel Port 318" that came with an 850 Holley and .525" lift cam. Those are extremely rare these days. You had to have the secret option code, BS1. Only a few dealers even knew about it. Factory rated at 205HP due to the extremely restrictive log style 318 exhaust manifolds.
