[Diy_efi] Big Caddy

[Jason M.]

I've thought about the old cadillac portinjection.  The engine I got came 
with an edelbrock performer intake on it which is a much better design to 
start with.  Haven't checked yet to see if the injectors can be aimed 
correctly using that intake.  Was thinking about a small block chevy TBI 
unit minus injectors, since I have the original from the 4.3L that came in 
the caprice the caddy is going in.

Really don't have much money for this project since I went back to school. 
What really got me looking into it is the price of a megasquirt, cheap, and 
the car originally was fuel injected so the tank has the correct sending 
unit and I should be able to reuse a lot of the engine wiring.

Still need to read more about the megasquirt, but really sounds like a good 
piece.  Assuming you don't screw it up putting it together.  For those that 
haven't looked at them before, essentially you get a bag of parts that has 
to be soldered together.

btw, I nearly got a 472.  It was installed in a bus (motor home project that 
got as far as bolting an engine in), back in the woods and sunk in the mud.
