I am purchasing a 305 next friday if budget allows... It was rebuilt 7k miles new pistons refinished crank, re used rods.. The heads were completely ported. It has a zz4 camshaft, ported plenum, 22lb injectors, custom mail ordered chip, ported throttle body.. He is throwing in a holley throttle body as well 58mm, he said the engine wouldnt run right with it..
The TPI engine is coming out of a 90 iroc auto i beleive he said..
So, my questions are
1) estimated power?
2) since im dropping it in my car should i keep his chip and run map? mine is a t5 maf.
3) any suggestions on anything else?

P.S. i will be putting on shorty headers and getting a custom y built
