ok i have a 96 tahoe 4dr 4wd and it has a slight knock not bad but noticeble ok i wanna put a 406 big block or maybe a 383 what mods would i have to do or any suggestions on what to do
HT383E if you have the money is not a bad option. The only change that NEEDS to be made and I do not care what GM says is a custom tune. I run the HT383E in mine and I have been very pleased with it.
Yeah do a HT383E its gonna be your best option, no modifying its a direct bolt in just need the tune like Bowtiefreak says. When I do the 4L80E transmission, I'm gonna do an LQ4 swap. I can't wait.
