I have a 1999 tahoe which the tranny went out last year. I had rebuilt the engine earlier in the year after realizing the intake needed to be done while i was installing the new water pump. And that was after i had just installed a new 6 in bds lift and tires a couple months before.
But my plan is to build this 14 sf i have sitting here with a new posi but im not sure if i should stick with 3.73 which i currently have in my 10 bolt but im gettting a new 4l80e with stand alone computer unless i can find a 6 speed setup somewhere that someone has done on this body style.
motor is my question spot, i have thought about the 383ht but not much power for the money and then there is the zz454 and zz502, thought about the ramjet 502 but sounds like there is still issues with the computer which i dont feel like sinking more money into. fuel injection/carb is still questionable but not important as this is a street rig when i decide to drive it but not used as a daily driver as its been sidelined most of the last 2 years.
Im new to forums and im sure there is plenty out there on motors but whats the opnion on the best route. zz 454 zz502 lsx454. along with that what about the axel ratio to keep road worthy since im not sure how much the motor matters. I guess also has anyone used or heard much about those new front axel shafts, rcs i think it is?
