Chevy EFI Mods

[John Napoli]

I am considering the replacement of the stock 350 in my 1988 Chevy truck
with either a 350/350 or a 383/350 from an aftermarket source.  The truck
is a 4x4 (1500 Series) used for street stuff and occasional towing. 

I am interested in more power and torque in the 1200 to 4500 rpm range.

Assuming that either of these motors are appropriate -- and both come with
an Edelbrock manifold, perhaps a Torquer -- what modifications are needed
for my TBI to compensate for the extra displacement and increased flows?

Do I just need a new chip -- are they available and from where -- or am I
looking at extensive EFI mods or a carburetor.  Neither of these
alternatives is very appealing just now.

What happens if I just bolt the old EFI onto the new 350?  Or the new
383?
