I agree FBO plate in both of my trucks now. 3rd plate on the bench for the 88 police engine I am fixing up.

my 440 with whiplash worked out at 18* initial 18* mech 36* total med spring all in by 3000rpm. vac pod blocked off.

318 roller cam whiplash worked out at 14* initial 18* mech 32* total light spring all in by 2500rpm. vac pod hooked up.

I played with the firecore dist and never got it to work right. dist failed 2x coil failed next. CD coil still did not fix issure. so it is on the bench as a paper weight.

I will be going back into the 440 dist and will give it a try with the FBO locked out on 0* and install a pertronix point conversion.

pertronix points conversion = 80$ FBO = 20$ 100$ total

ez pz and cheap.
