Yank or Circle-D

Thinking bout doing a cam/converter swap in the ole 4.8. Planning to go with a 220/220 .581/.581 112 with either a Yank TT3000, or a Circle-D 3000-3200. I can get the Circle-D for $375, or the Yank used for about $350

I am running a yank sst3200, it has been flawless. However I have never heard of a problem with Circle D.. Both are top notch companies and have great service...

i run a ls1 3200 yank for the 80e, and have ran a 3000 and a 3600 yank in my 60e all of em are still going strong, in other trucks, but i have friends that are running circle d and have no issues also, they are both good verters from what ive gathered, i guess its just preference, also im brand loyal so thats pretty much why ive stuck with yank :thumb:

both have good rep... but my vote is circle D

bout to install a circle d myself

I got the Circle D 3000, it stalls right at it! Great mod
you will need a trans cooler for sure though

flip a coin.

I love my Circle D. I bought it used here and no problems.

Circle D

circle-d by far ;)

plus there a sponser of ls1truck ;)
