Longtubes

ms3 camshaft
I have a ls6 intake but was thinking about going bigger.
springs, rods


I have heard alot of good things about yank, and heard alot of people complain about vigillante.

Any suggestions from what you guys run, and what size should I go with?

 

Yank and CircleD seem to be the preferences here on ls1tech.
talk to/e-mail both and get their recommendations.

 

CircleD 3200 for over year about 14k miles with no issues. I'm only a bolt-on now so your app will be different.

 

We have had good luck with Vigilante over the years. The biggest problem that people face when installing these converters is they just slap them in and go. You HAVE!!!! to check the converter spacing. The pump needs propper engaugement from the converter snout. Sometimes they require a small shim and longer bolts to get the depth right.

 

Circle D all the way. Im guessing your running a 4L60 correct? If so the 4C or the 5C from them would be the converter of choice.

 

vigilante and yank have great reps.

 

I'm pretty partial to the record setting performance of FTI competition converters but hey thats me. Give us a call as well 1-866-726-8358
