its whats built into the distributor and the curve red. seems to work for those who try it.like I said just trying to help and I did have a $6000 454 nova that would blow your doors off.it went 10.90s but I blew the 10 bolt rear at the top end

first off if you read my post, i have the msd setup with the no vac adv. dist. i did just like 69chrgr and put the black 18* bushing. and i have the light blue and light silver springs in it. unless yours is locked out, you HAVE initial timing.
i just got done with a 454 68 nova that would blow my doors off too. does it drive good on the street? no. too hot. breaks loose the rearend at a drop of a hat.

even chevy guys know to put a 12 bolt or ford 9" in with a bigblock and not blow a 10 bolt.
