Yeah, i understand. Just looking for a guess anyway. Not sure where to shift this 511 at once i get to the track. 330cc heads and a 270@50 solid cam. Seems to pull hard to upper 6000 range. Thanks
Solid roller or flat tappet ?
For what it is worth , my 505 with a 272@050 solid flat tappet .5400ish converter , 4.1 gear 28"radial .
Chassis dyno always showed peak HP at converter stall(5100 footbrake vert) , but motor pulled to 6500 without any drop off
With CNC source heads , Victor and 4150 prosystems carb I shifted at 6000 . 10.50s . I tried a little more not big gain , but it never seemed to give up under 7000 with either converter .
With TF270 heads , bigger tbrake vert , Super Victor and 1050 dominator . I only ran this a couple times . BUT shifting at 6000 it didn't fall back onto converter , shift light stayed on @6000 - so stall increased .
10.25@130 .
I believe with the bigger heads it wanted a higher shift probably 64-6600 which would have allowed rpm drop back to converter on shift
That is now to be another day , due to block issues .
Why the low shift ? It ran the numbers I wanted and was doing it easily at low stress .
