I'm running a D1-SC on a 408 low deck, cnc ported e-heads, hyd roller cam, 8.0 to 1 compression, blow-thru carb, 4-speed with a 3.73 gear dana.........all under the hood in a 67 belvedere wagon. I love the power. Docile to drive, until the 17 psi of boost comes on. Yes, I have two much boost, time to change the pulley.




17 pounds of boost! Wow that's nice! I wouldn't say that's too much boost, I'd say that's time for an alch injection kit!
