Hit a road blok in my swap. I have a 91 tpi camaro, and have swapped out my 305 (which runs on map sensor) for a rebuilt 89 350 tpi. (which runs on maf) the main problems I'm having is A: the car wont start/prime/crank and B: something is killing my battery in 10-15 minutes. my interior lights are on and i get a the "check engine" light, my fuses are fine exept my accessory fuse insta blows. any thoughts?

 

Need more details about what you changed and what you reused.
