79 C10 swap with L92 with 6L90

[nlped]

That's a heck of a jump from 1st to 2nd, but I now kinda understand the 3.08 gear. I still think I would have gone a bit steeper though .

Thanks guys

The truck originally had 2.76 which i was going to keep but i was worried that it keep shifting between 5 & 6 with road waves so i thought 3.08 will be nice. If i feel that the truck is lazy i change sometime.

At 65 mph and assumed 28" tall tires you will be at 2046 rpm in 5th and 1602 rpm in 6th so I think it will probably stay in 6th on the freeway with the power that L92 makes. With shorter tires it will definitely stay in 6th.

better then my th350 going 70 at 3100rpm

I'd love to see only 3100 at 70 mph, I'm at just under 3800 rpm even with my 32" tall tires.

mine has a 3.42 gear with stock 28in tall tires.
i needa upgrade to a 700r4 to have a overdrive

With the relatively light truck you are working with you should have no problem hitting 20 mpg if you can manage to stay off of the accelerator. That was always my problem after a swap, they were just too darn fun to drive mildly enough to see what kind of gas mileage they could get.

Toss a turbo or two on there and you can pretty much keep the same MPG you were getting cruising down the road but have a great power increase when you want it.

Yeah your right it was hard with my old engine even though i got around 8MPG i don't know what i am going to do with that

Turbo will be nice but I am worried about a putting stress on the trans cause they haven't got anything for it yet although the shop told me it good to 600rwhp but that not reliable assumption it all depends on who's driving

It give the truck a factory look under the hood.

man those are the heads i want to go with when i start adding go fast parts.

You will have no problem getting 20 mpg. I havent seen what ive been getting lately.

Honestly, the 6L90 may just be having the same intro years teething problems all the trans seem to have when they first come out. GM will get it dialed in over the next couple years after getting some warranty failures.

600 hp to the wheels is nothing to be ashamed of. It takes some minor mods to make a T-400 handle that reliably. Getting that bone stock is nice.

You will have a great truck when you get it done.

Thanks for the offer but i think i stick with 6l90 cause it got 4l80 internals 600rwhp is alot of power for everyday truck i think if i pass the 400rwhp i be satisfied
