Ok guys I'm wanting to supercharged my lil 4.8 but its already cammed with a 216/220 114lsa comp cam and ls6 springs question is can I keep the setup and put the blower on or will I have to start from scratch

 

That will work just fine with a blower

 

agreed. not 100% optimal, but it will suffice. how about your drivetrain? any work done to it?

 

Yep, good sized cam with not too narrow an LSA. Should work great.

 

Looking at swapping my 4l60e for the 4l80e and I still got the 342 gears

 

the 80e has a great reputation. I cant wait to get mine in! Since you are in houston, I would give chris a shout about a converter for that 80e. (He is getting my business for my converter as well). Im going to assume your wanting to change your gear ratio? If so you might want to look into a locking differential.

There are some great and detailed build threads going around here. preston129 has one going on right now in the PROJECTS GALLERY. check it out.
