what size of harmonic balancer for 383? i'm getting close to completing my 383 build. i know there is a variety of different harmonic balancers for an internally balanced motor out there.
i wanted to know what size i should use. and if anybody had any suggestions on brands?

i think most will univerally agree that the ATI super damper is the best on the market. from what I remember, you'll need the 7" balancer (its all based on stroke). i have a 355" engine, so I use the 6 3/8" balancer.

What rpm range is the engine running at? Has the engine been balanced? What is your budget?
well, you ground my cam for it a while back. and gave me a list of valvetrain parts to go with it. you said it would hit peak power around 6800 rpm but only loose a few horsepower all the way 7200 rpm. and yes its balanced. i'd rather not spend more than $200.

Sorry about that, I wasn't paying attention to your login ID.
I would run a 8" PowerBond balancer, this will fit into your budget and have a good balancer. http://www.competitionproducts.com/p...s.asp?dept=715

thanks guys. i think i'm gonna go with the powerbond. i am on a budget.
and shane, my build is still coming along. i've had to put it on hold for a little bit so i could save up some more money. i put your cam in a couple months ago. then i was sliding in the lifters and one pair of lifters wouldn't slide in right. it was kind of cut wrong. so i'm ordering a single pair from summitt. i'm probablly gonna try to get the motor running on the engine stand first before i put it in the car. i'll try to post some vids of it.
i'm curious to see what the ls1 style lobe design will sound like. haha. yhanks again man.

. In all seriousness they have worked out quite well for me and his car should be pretty roudy on & off of the giggly gas.
