Hi guys , i have a 98 1500 w/t 5.7 . I've been told you can swap any trans so i bought a parts truck 94 v6 manual trans to swap in mine , hopefully everthing will work without to much trouble . My big question is if i want to swap a 6.0l in my truck later would it fit with that 94 trans, do i need difrent flywheel , flywheel housing , headers, different dif ratio ? Any advice for me anything that could help thanks
