I'm currently running an aftermarket stock-type electronic ign in the 426 wedge in my 64 Polara and I'm thinking about going to an MSD or equivelant system, including dist., coil, and box. The motor has 10-1 flatops, 513" lift cam headers, little port cleanup on the heads, Edlebrock intake and 750 sp Holley. I also have an 800 dp Holley to install. Running a 4 speed and 3:91's. How much power increase can I expect with the new ign. system? Will the power increase be noticable? Would the gain be worth the cost, or would I be just as happy just putting lighter springs in my current distributor?
