Its said the newer 80s, that have the cooler lines about a foot apart are a little better than the older ones.

I think the weakest part of the 80s is a spag? IIRC.

If you don't need a tranny that will hold up when you add hp and tq, stick with the 60. If you want to fix it one time and have it last, jump to the '80. It's just that simple.

Don't know what size truck you got but I have a RCSB and I love my 4l80e! Paired with a stall, I never suffured a lose in power due to the added wieght. It was cheaper for me to buy a 4l80e core, a stall AND get it rebuilt than to build my 4l60e to the same power levels.

People still break built 4l60's . 4l80's don't break

How much larger is the 4L80E than a 4L60E? is it only slightly larger or quite a bit larger?,...I ask because I was wanting to do a set of long tube headers from Current Performance, wondering if they would still clear with an 80

This maybe a dumb question and Im sure has been discussed a thousand times over, but is the 4L80 just plug and play, or is there some other modifications that have to be made? Re-tune for the shift points?

U will have parsitic power loss tho...never did the actual #'s, but generally expect anywhere like 75+/-rwhp. Thats the trade-off for durability and why if ur headed for ~450rwhp its a push. U have to by a conversion kit (SpeedEng or other) for about $1200 (?), and ull need the stock programming for the 4L80 at a min. R/
