[Vortech 4.3]

i am looking to get a new/better damper for my engine. its a 97 vortec 4.3, so i don't expect you to know what will work. but i have read that a regular 350 damper will work, but i want to check things first. i believe my engine is internaly balanced. so i believe this means i only need a "damper", and not a "balancer" ?
my stock damper looks to not be "balancer".

what size is the crank snout on a newer 5.0/5.7 ? i am figuring a good regular damper will fit ? what is the difference, other than size, between a 6" & 7" & whatever ?

street engine, a few runs down the track a year. around 6000rpm.

thanx

the best hint I could give you is to check out FLUID DAMPER superb product . the difference between the two dampers is one is for an externally balanced engine 8'' usually a 400 crank and the smaller is for an internally balanced engine. If you are not aware these are not cheep 300.00 but well worth the $$. They really help the timing to hit dead nuts . I do not think you will need to worry about the snout size the manufacturer will have that all figured out for you .

Ive seen a couple dampers off 4.3 core engines that were not neutral balanced but never knew why.

Be aware that the damper for Vortec engine is not same as older engines (pre 1996).

Its slightly narrower to allow for reluctor wheel thats sandwiched between damper and timing chain gear.

If you put the wrong one one there youll start eating belts.

thanx guys. i thought this was passed on by.

i am 99% sure this is not a balancer, and it is 6" . so i will see what my suplier has.
