I am about to trade a single carb tunnel ram with holley carb for a sbc tri-power. Buy the looks of the picture I have of the setup it looks like the carbs are rochester 2gc's. I'm curious as to the requirements that the carbs have for fuel pressure. Can I use a standard mechanical fuel pump, a high pressure mechanical fuel pump or an electric fuel pump?
Thanks in advance for your tips. You guys have been a lot of help for me so far.
The tri-power will be going on a sbc 283 w/4 speed in a 28 ford 5 window.

Standard fuel pump should be alright though you will have to run the fuel line through a fuel block as I'm sure you know. 5- 5 1/2 lbs of pressure should be ok. Could be wrong.....any imput, no pun intended, guys? <img src="graemlins/pimp.gif" border="0" alt="[pimp]" />

We had a lot of fun about twenty years ago with a '66 SS Impala, with a warmed-over 350 running a tri-power/4-speed/4.10 combo on the street. The carbs were a matched set from a '65 GTO (the end carbs were larger). It ran just fine with a stock fuel pump, fuel log, three screw-in fuel filters and an Eelco progressive linkage. We ran a divorced choke on the center carb. Enjoy!

Thanks for the help. Hope to have a lot of fun with the tri-power.
