The regular Comp Thumpr cam specs are 219/233 .553/.536 109 LSA for the LS series engines.

It has a bigger split pattern kinda like some of the TR trutorque cams.

Comp says "stock converter ok, best with 2000 converter & gears, choppy and thumping idle.Rpm range from 2000 to 6400".

What engine / truck do you have? If you have a heavy *** Crew Cab or ext cab, I would put some kind of higher stalling torque converter over the stock imo. A Circled or FTI 278mm would be perfect.

With you being a RCSB I'd get a FTI or CircleD 278mm 3200rpm converter. It's a good DD cam and you could still tow light loads if you wanted with a big trans cooler such as a tru cool 40k. I know plenty of people using the 278mm 3000rpm converter and still tows light loads fine. The 278mm is just a little bit smaller diameter over the stock converter and is still a tame converter. Later on if you want more, get a smaller diameter converter over the 278mm and if you start upgrading more things a built trans would prob be a good idea too.

Did one in a 03 silvy with a 5.3/w 180k on it. Could have used a valve job too but the owner didnt want to spend the $

With lts and a cai it made 320/340...took alot of tuning but drove pretty good with a stock converter. I was pretty impressed as our dyno dosent read on the high side.

EDIT.. It sounded badasssssss

could you run ls6 valvesprings with this? my project truck has an ls6 cam but I am thinking a choppy cam would be pretty cool.
