just recently did 6.0 fully built swap and now on to my transmission! i got a little to excited and ordered a yank performance stall 3k for my 4l60 was thinking of beefing up my 4l60 truck with nitrous going to be pushing about 650hp some people tell me it won't hang other that it will i have a buddy selling me his built 4l70 for 1500 bucks and if i go that route i can still use my torq conv i just bought but then again to beef up my 4l60 its 1200 bucks which is not big of a difference and others just tell me to not waist my money and just do 4l80 swap and sell my torq converter and get another one

I would just do a 4l80e and call it a day.

650hp ...Yeah 4l80.

I think 500 and less is still 4l70 range.

do it right the first time and go 80E

How in the hell do you still have that 4l70 in your truck still and not on ground? Man I was nice to my 60 and it lasted like 1 month!
Is your trk standard cab? Seams like those are great times and mph.

I have a good builder and even better tuner.

2009 ECSB 4x4 that weighed 5600 with me in it.

I flush the trans system once a year.

I pushed my 65e to a 12.3@6k lbs. it's still together and fine sitting in corner or garage in a trans case.

But I still don't trust them.

It just amazes me how short lived my 60 was and how some of you guys still roll around all day and even been to track with 4l60 &4l70. Oh that would be 2 60s I went thru within 7k miles. MAN, I cant not wait til next week to finally drive my truck with the 80 and converter in it!!
