Does anyone out there know how large you can bore a 2.7 liter? Tried towing through very hilly country and I was not impressed with the lack of power. Pushing the extra power button helped some but I kept losing speed just towing a 500cc Honda Shadow up hill. 4 speed auto was down into 2nd and I was still losing.
Can the 3.4 be switched out using the same 2.7 transmission, with a mod kit, if available of course?
I love the truck and it has every imaginable option I could want but we're heading out to the Rockies next spring towing a lightweight Casita camper and now I'm concerned whether or not I should be looking for a different truck? It pulls seemingly without effort on flatland.
I ordered a performance chip to see if that might help. ????????
Any advise would be appreciated.
