This cam pulls hard up to 5200 then tops off.

Seems like every system I have looked at is 1600 to 2400
is there a cheaper solution that I am missing?

A DIY setup is Megasquirt, I believe they are quite cheap.

The expensive parts are the throttle body and fuel rails. If you can find cheap ones of those that will actually fuel your motor, then you'd be well off. Something that big is not going to be cheap to inject and extract it's full potential.

The Holley TBI with the Commander 950 module has been a pretty good setup for the money and will easily support your horsepower/airflow needs and will grow with you if you decide you have a need for more.
I have a 406 with a GM TBI setup that works pretty well, had to buy a big throttle body and up the fuel pressure then spend about a month getting the chip right, but it only cost 4-500 bucks for everything.

 

[TWISTEDJACK]

So I could buy an after market TBI only, source the right ECM/sensors harness off a junkyard and have a chip burned or buy some software to program it myself to got the cheap route. It looks like to make a TPI run right it is going to be big bucks.

you could buy the big block tbi system I have for sale and send the prom to howell and have them reprogram to run your engine
