I found this $800 for turn key with accessories, harness, ect. Would need accessories, intake, and exhaust from LS1. So maybe $1250 for all of it. Then getting the trans to bolt up probably needs a bellhousing and crossmember. Yea. Ill definitely get with someone who has done this before. My career in HPDE pre CMC license, will definitely be running the 305 vortec TPI. As long as it lasts, im gonna run it.

Looking at the spec carb route, the intake, carb, cam, ect is gonna be over $1000 and that doesnt even include the rebuild. But the engine would be fresh vs 150,000 miles on the 5.3 LS.
