Looks like a good list. Let me know how it goes, I'm looking at doing a similar swap into a 89 RS. I'm going with the GMPP 12496821 manifold though for the EGR.

Re: LO3 305 to L31 350 swap parts list. Did I miss anything?
You cant just drop that thing in behind the 700R4 since its a TBI already. What is the least amount of swap parts that I need to go in place of the L03, and use the stock 700R4. I'm looking for the least painful/expesive way to be able to lay rubber w/ my right foot, also putting a rear end from 02'Z28 w/ 3:42's, should be healthy since my brothers 1996 single cab 2wd stepside 5.7 L03 w/ 3:73's was a beast, I mean quick, it used to hang w/ my 85' TPI Vette to 100mph.

Correction, typo, my brothers chevy was a L31, accidently put L03, but it was insane for the day back in 96' when it was new, just a cat-back and a K&N
