426 wedge build

Day one on the dyno.

Motor runs strong, very torquey, crisp accelerates very quick. can simulate load and driving conditions on the dyno. will run very nice at hwy speeds, and when you whack the gas the thing will take off.

So far we have moved the timing up from 29 to 32, made one jet change, and tried a carb spacer. The motor loves timing, hates the carb spacer and picked up 10 foot pounds of tq at 2900 by dropping the secondary jet from 87 to 85. So far we have only pulled the motor to 5600 rpm. Motor makes 512 tq at 2900 rpm peak tq 540 tq at 4200 to 4400 then carries 500 foot pounds to 5200 then slowly starts to drop off. At 5600 we are making 510HP. i love the huge tq curve this motor has, its going to be a fun little car. Will put the rings through a few more heat cycles tomorrow then make so higer rpm pulls and see what the motor likes? I am not too worried about peak hp, i would rather have the tq.

I am wishing i would of maybe gone with a holley HP carb, as they have adjustable high speed air bleeds. mine does not, it only has adjustable low speed bleeds. We are so close, that we may split the difference on the rear jet to see if the lean spot goes away? Its not real serious, but just one of those things you want to adjust.

Will post More tomorrow.
