flexplate

[enjoi355]

im gonna be getting a stall soon, but before i do i want to get some stuff together... i was thinking a new flexplate from tci, but when i looked there are two : neutral balance and external balance. which one do i use??

[Fixxer99TA]

If I remember correctly, all LT1 cars are neutral balanced from the factory. Someone else will have to chime in on that though, I am really not sure on that.

well I see that you have a 355, did you use the stock crank when you did that and how did you balance it? with the stock flexplate? the stock flexplate does have the external weight on there.

[enjoi355]

its a stock crank, not balanced, stock flexplate

[enjoi355]

so if the stock one has the external wieght, then thats the one that i use?? just want to be 100 percent sure even if the answer is clear

[grn95t/a]

yep you need the weighted one.. i have a tci with around 500 miles on it forsale

Depending on what your goals are you may want to get an SFI approved flexplate.

I know this is old, but do we need the interal or external balanced flexplate on a stock motor?

[Green96Z]

Externally balanced for stock engines.

For anybody that needs some good info:

Jeg's sells a SFI flexplate that is externally balanced and works perfect on LT1 engines. I bought this exact one at the recommendation from a very well known transmission builder. I paired it with all the proper ARP flexplate and converter bolts and it worked out awesome for my build. Good price too...
