I have an 87 FB Formula 305 TPI, 2.5" exhaust. I am planning on having a local speed shop do a swap to a 350 (~275 hp...due to $$$)around October. They will re-use the stock 305 TPI intake setup. R there any additional costs I should start planning for, besides the following (and any reccommendations on those):

*new injectors (22#, correct???)
*new headers (R ceramic coated worth the $$??)
*torque converter (daily driver,stop&go,5 miles from work)
*PROM chip

I want it to have decent zoomzoomzoom, and still be able to get 40/gallon....(yards that is!!! ;-) )

Thanx in advance...
