I would take a little time now and buy a ATI dampener that will work with the blower drive and have the motor either rebalanced externally or internally before hurting it messing around with a unbalanced blown pump gas motor Cheap can be fun when done correctly Not so much when the car is on fire from a rod exiting the block at 5500 RPM BTW, a low compression motor, under 8.0 to 1 with low boost, under 7.0 lbs doesn't need the timing retarded, at least the last blown pump gas hemi motor I dyno tested didn't 33 degrees with 7.0 lbs at 7300 RPM made 924 HP on CA pump swill a bunch(2002 or so) of years ago

Haibach,
I think it will be fine, I have run a nitrous fed cast crank stock rod 440 in a 63 Plymouth to a best of 9.69 135 , that was 15 years ago, I belted piss out of it and the engine still lives. It has been semi retired now running NA 11.00 in my sons Aussie Valiant street strip car, all good.
5 lbs go for it !!!!
Cheers

RUN AWAY from the Summit balancers. I've owned 2 and on both the rings have become separated from the hub. Caught both before a disaster, and of course Summit was told and couldn't have cared less.
I don't believe in skimping on balancer quality, but if you are watching your budget I've heard nothing but good things about Pioneer balancers. We have a Summit one down at the shop...Total junk. Timing marks are way off.

Not sure if this is an option for you, but uhh,...why not just use a factory 383 steel crank & loose the cast flexi' stuff? Dunno..just a thought?

And if you end up grabbing a 383 crank, just use the hub, wouldn't spend the $$ on a balancer, the belt should absorb the harmonics (as long as everything is weight wise equal enough) not building a 2,500 HP nitro engine ya know, & I wouldn't be scared of 8 to 12 psi boost, use ARP studs & the good fel pros,... I'm doin same thing to my dad's duster..lol
