Cheep EFI maybe?

[bbmonte396]

I have a 402 guess to put out 350hp
216/216 @ .050 .515 lift and I think 110LSA
9.5-7:1
I found a EFI system from a 1988 Chevy 454 it came with the intake manifold, TBI, Distributor, ECU and 100% on the wiring. I was looking and the CFM rating is around 670?
would I lose power compared to running a tuned "not well tuned" 750 Q-Jet? would the fact that it is EFI make up for the less CFM?

I like playing a round with computer so for me to be able to plug it in to my laptop and tune it on the fly with an after market ECM like a Mega Squirt. I think would be cool.

You can check out Http:\\www.dynamicefi.com
The GM TBI stuff is updated nicely to be able to do on the fly tuning etc.
Many of the factory problems have been enhanced or corrected with the setup.
IMO, If your looking for full all out power than TBI won't get you all the flow that a staight carb setup may,
Or if you did get it setup to provide that level you would have idle quality issues etc from large injectors running small pulses, etc.
For what you are looking to do, its a good thing to do.

x2. I am running the EBL from dynamicefi on my chevy wagon, with spray. Using the 454 TB and 90 pph injectors. Takes some time to tune it. But the driveability is well worth it IMO.
