Wouldn't suprise me Dunc, Rob is as good, if not better than Geoff on heads......

your right les the koffel mtr in bills cuda / slipstream ran at best a 10.1 mostly 10,2s the car changed hands had blinkin Bananarama! thrown at it ultimately ran about a 8,6 with lots of gas 500 cubes ally heads the koffel iron head may just have dibbed a 9 prior but yes it was revved to Bananarama!, i nearly bought that slip stream car knew bill through the jensen connection,
yes the yellow dart really was about as lihgt as you could get it i forget the blinkin name on the sides now, mopar mark will know ,
your 10.7 no gas seems more credibal than your actual nitrous pass that would be pretty impressive even now from a straight up 440........
Well perhaps? depends on how you look at it, It was just starting to get interesting for me with that 10.7, but unfortunately other commitments in life stopped me from continuing the On Motor only approach which is really what I always preferred to do, so I just hit with some gas to achieve what I wanted, but you still gotta have the chassis to cope with all that +hp.
But I did hatch a plan and that was...go to much much lighter rods/pistons, the 6-pack stuff weighed a TON, would've upped it to at least 12:1CR to suit the .650" cam which would've then worked a lot better, a 1050 Dommy over the puny 850 I had, there was hole bunch of extra hp. The 906 heads from Hauser were ok with big valves, but I don't know how much more cfm flow I could've got from them, never had them flowed, I don't think he did a mega port job on them, they were done for Dinger!!...so with all that in there, a few changes to the chassis, I reckon a 10.4 or even a 3 was in it on motor, and a subsequent 9.4 with gas.
However, all this is almost irrelevant, as I never did it, so we'll never know, but I doubt if those heads would ever have got me in the 9's on motor in a 3000lbs car....you need at least 320cfm heads for that, and 906's/452's are way off that figure, more like 290 if your lucky.
