Since were on the topic, I have dual holley 750's dp going on my 454. They have 4 corner idling circuts. Is there a difference in tuning? If so please shed some light on this for me when I fire up my new motor.
Motor is a bbc 454 .30 over with 11-1 comp,weiand tunnelram,msd-(dist-cap-coil-wires-6al), DRY headers,cam(256@.50,soild,.615 lift,108 lobe).
I have printed all the above info because my "other" boat(455 olds) has dual 600's vac sec on it and I can use it for refrence. I just need some refrence for my 454 now
