i have a 99 silverado 1500 ext cab 4x4 that i am swaping a 6.0 into with a yank 3000 truck converter my truck has 4.10 and i pull my 01 camaro to the track other than that i just drive it i'm think of buying the big mother thumpr what do you guys think i know its big but when i pull with my truck i'm above 3000 rpm and it would sound great

 

235/249 @50 .573/.558 109LSA

Looks to big for a tow vehicle I would think. Would probably require a much bigger stall and that would be bad for towing, you are pushing it with a 3k stall, hope you've got a serious cooler on there... but we'll let our resident sperts chime in.


But yeah, it'll sound great.

 

i wouldnt think that thing would like to idle let alone tow.

 

24 degrees of overlap! That would probably be the single worst cam you could buy for what you're describing

 

bad, very bad idea....how long have you been thinking this is a good cam for your application?

 

I just ordered the thumper,ill keep you updated

 

^^^ What they said, that's too much cam for a tow vehicle, I'd keep the duration alot lower. Search here and the internal section and you'll find alot of 6.0 towing options...

 

get a custom grind, 224-228 duration, same lift on a 108 or 109 LSA, it will still lope at idle but will work better with your stall and you can still tow with it. and make sure you have a nice tranny cooler, like a tru-cool 40K

 

Id get something like a tr220 or tr224 with that converter and your plans to tow.

That doesnt have much lift for having that much duration.
