what dampner would i need for a 383? it has an internally balanced crank so i dont know if i need one from a 400 sbc or a 350 or neither???

 

350 if it is internally balanced

 

good to know. i wasent ever aware that it was possible to have an internally balanced 383 but i have papers about my crank that says so. its a 400 crank but internally balanced so im going with a 350 dampner. if this isnt true someone jump in before i break something . anyone have any good brands to try...i found this brand for a great price and its SFI approved

If it says internally balanced, then it shoud use a 350 balancer.

I would not send my money to China by buying CAT stuff, if I could help it. Personally I would pay a couple more bucks to keep it in the states if I could.

 

now what size would fit best??? 6 3/4 or 8"???? and does one do a better job over the other?

after what i have heard CAT is defenitly out!!!!

 

You can use eather.... They say the 8" dose a better job but I don't think it is really going to matter. I use 6 3/4" on my internally balanced 383

 

ok so it really doesnt matter between the different sizes.....

but what about the different types, ive heard fluidampners are the best but then ive heard a soild dampner works well too. which one is preferred?

 

I Run a fluid dampner but that is just to say I have one....lol It would depend on what you plan on doing with it i guess....... There is a wide range of them........... Me I would go with something that is SFI Approved just because I would know it would not fly apart on me. If you are looking for something just stock the summit has OEM ones for 59.99.

 

i defenitly want an sfi approved dampner. probably a fluidampner just because ive heard so much good about them

 

A Little on the $$$ side but good!

 

hey CamarosRUS

Do you have to run 6" rods on your combo to run the internally balanced crank?
All the internally balanced cranks i checked into (one peice)for my 383 buildup specified a rod of atleast 6"

 

well do i HAVE to im not sure. but i am running 6" eagle h beam rods with my setup
sorry i couldnt help more, id say go for it anyway, give a little more torque

 

Sounds awsome i already ordered all my parts so cant change now sounds like your engine is gonna rip though.It was little frustrating figuring out all the different balances and parts needed for my build up.Didnt know new small blocks were externally balanced wich really through a curve ball into my thinking hehe but gotter figured now.
