Jeff unless your wanting to turn over 8K RPM, what you have will more than handle it, recurving you dist. would be about the only thing worth while, the bucks spent on a new system could be better spent unless your down to trying to get that last .oo1 down on the time slip,,,,,,,, In a message dated 3/19/2010 11:14:57 A.M. Central Daylight Time, ledman_70@xxxxxxxxxxx writes: 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?
