fuel injecting a '73 vette

[Dave Zug]

you dont have to reprogram anything possibly.. use a MAF type 
computer, and not many mods to the vette motor.. slap on a Tuned port
system intake from a 85 or 86 5.0 or 5.7 litre (5.7 prefferably - the
inkectors are sized better for your 350) - install a harness from the
same car, or buy "painless wiring": type harness from aftermarket. Get
some kind of oxygen sensor monitor and/or a exhaust gas temp sensor
or a scan tool / laptop scan kit and see if you need to up the fuel 
pressure or drop it. idle with a big cam can be tough. the 165 
computer is MAF, and like bruce says - the 730 is MAP and may be 
ultimately a better choice.. depending on your skill.

coarse if you want to squeeze max power fron the engine - gotta get
some aftermarket air intake stuff $$ and head work , cam etc then you
must tune the computer.  If you plan on going for lotsa power and tune
anyway, some more knowledgs and  a MAP type system is better ...
others may have opinions on this.

I have never done a conversion or swap but have helped change a 350 
block where a 305 was, and tuned my own 350 (MAF) for a supercharger 
with some success - my experience is not what others' on here is 
so...

Yes folks I still have the 86 305 tuned port intake and harness and
computer here for sale ;-P still havent ebay'd it.  considering ALL
offrers from $1. free 305 shortblock if you buy the TPI and pay
shipping or pick it up (MD)

okay sorry for the commercial.
