some one told me that you can run a holley 900 cfm tbi with a custome chip on the stock computer if you splice the injector wires together.

 

it's been done

 

ya but dose it work and how well or is it beter just to stick with the 670 with some 85 pph inj.

 

a 670tbi is measured at 3 in of vacum. To compare this to a carb which is measured at 1.5 inch of vacum the tbi now only flows ~460cfm. Bolt a 460cfm carb on and see how fast you can go. In a camaro it will get in to the high 13's. If you have a truck, I'd say slower.

 

there is no way in hell that my 350 will be happy with less than 500 cfm now what am i to do i thought that they where both at 1.5 dam carb back ground gets me again

 

1)be happy with 14's and lots or torque
2)get a carb
3) get a 900cfm tbi on off ebay.
Oh holley makes a computer to run it instead of a custom chip., if you want. I'm sure you knew that though

 

how much dose the 900 cfm ecm unit cost on ave
