Heàds had mild port and flow 260 intake at 500 and 165 exhaust at 500. 1 5/8 full headers 2 1/2 exhaust. 3.55 gears, rpm airgap with Holley 750 but not DP. Mallory all in one dusty, 9.8 compression, tires 25.7 tall. I have the pushrod checker ànd can check clearance when the heads come off. I have a solid lunatic now but to much durAtion for street. 249 @ 050. Was thinking the faster ramp rates might more power than a solid. Also 1.5 Hughes rockers. I'm looking for more low to midrange power. 2200 up to 6 or 6.5k. thanks for all the comments. Anything welcome. I'm an old man now 67 but I still wrench and want to have fun.
