I have ran a .060 440 with a mildly ported set of Indy 440-1 by Porter racing heads (fast68plymouth )
11to 1 compression on 91 octane 10% ethynol pump gas only no additives
Comp roller 266@.050 .640 lift w1.5 rockers
Indy single plane with a 1050 dominator
Ross flat top pistons Manley H beam rods
TTI 2 1/8 headers 3800 lb 1965 coronet
4.88 gear 5700 stall 8inch converter low gear 727 trans by Ultimate transmission
30x9x15 Hoosier radial drag slick
10.30 et @130 mph 1.40 60ft times
Shift at about 7200
Also ran this car / engine combo with a Jericho 4 speed
Same et with about 1 mph faster
The key in my opinion is the guy that does the heads and cam choice ! (Fast68) Porter racing heads !!
