Ok heres the prob. I can get a full ls from as 97 teg for 750. Or i can get a ls block out of a 90-91 for like 350 and then rebuild it. Which would you do? + i dont plan on resleeving any time soon so are there any alternatives to resleeving if i choose to go boost? Oh i have a 93 ls now. Which arises the obd0 obd1 prob with the 90-91.
