I run a pro billet. I have it locked out with a crank trigger but ran it just regular before. Everyone I talked to said you want it all in early so never played the curve.
I used to be the guy who said bring it in early or even lock it out.
Then I learned how wrong that is. Came up on a forum. I said lock it out. William Baldwin said don’t do that. All engines want a curve and the timing retards with RPM.
I said that’s nonsense. He posted several videos. I watched them. Then I went right out and bought a distributor machine. I never lock them out or bring them in early any more.
And I promptly apologized to him for being ignorant.
