Ive got a 99 rcsb silverado and I'm woundering what my hp trq output shld be wih what I have also any 1/4 mile est.

Sits as follows lq9 swap,223/231 115 cam, k&n cai, 1 3/4 lt headers, e fans, 8.1 injectors,msd wires, ss3200 yank stall, 4l60e with shift kit and vet servo, trutrack, 4.10s

 

It should be mid 13s n/a no problem and as for numbers itll be in the 350-380 rwhp range depending on the tune.

 

That sounds preaty good I'm working on getting a 65e built then some more engine mods lol

 

Get a 14 bolt with 4.32s and a 4l80e with a 3600 stall and you will really wake it up.

 

i would get the 80e and a 3400-4k stall 1 7/8 headers ur 4.10s will be fine and ur factory 10 bolts will be fine mines been holding up to my 408 just the built 60e died twice

 

I've been told the gearing is of for me to get an 80e. I'm guessing the higher stall will counter the long first gear?

 

i run 4.56s with my 80e and love them. Makes for a perfect gear ratio. Not to bad on gas either.

 

What's your rpm at about 75?

 

He runs like 2600 or so brandon6.0 my cousin he has a sharp setup

 

depends on tire size. Had stock 31" tire was turning maybe 2600 at 60. Thin went down to 26" tire pushin close to 3000. But this is cruising without lockup. Trans wiring was kinda off when i swapped in the 80e.

Now JB ran something like a 4.10 with his 80e and it wasnt no slouch either. Depends on setup.
