Carb issues-what to do

I have a 1977 f-250 highboy. I was going to rebuild the 2150 2 bbl carb, but when I took it off I noticed the casting is broken. So now I need to replace it. I plan this fall to build my current 351m into a 400m bored .03 or .04. So my question. What intake and carb should I get knowing that I want to run my 351m this summer, and use the same intake and carb on my build. I had planned to replace intake and carb for my 408m, but never planned to use it on the current 351m. Thanks guys!

A Weiand Action Plus Intake and a 600 to 650 cfm carb with vacuum secomdaries.

... but start on dual exhaust and headers before upgradimg the induction side of the system.

I know its not optimum to do it first but It wont cause damage right? And I forgot to mention I found a pair of aussie heads ill be replacing the stock heads with....does that factor into intake and carb choice? thanks

I would just repair the 2150 carb by finding a rebuild able core and go .. Stock pile your parts for your build as you can afford them ..

Edelbrock Performer 400 intake and either #1405 (man choke) or #1406 (elec choke) 600 cfm Performer Carb .... add a Holley 12-803 FPR at 5.5 psi. It'll all work great with the 351M or later on, your 400.

OKay thanks for the input guys. I went ahead and just bought a reman Uremco 7-7583. But now im confounded. Its a direct fit but im missing some things on my new carb that were on the old, and have some new things that were not on my old motorcraft. I have a place for a wire to attach to the top of my old one, not on my new, I have a place to attach a wire on my new thermostat, not my old. I have a empty line coming from unter my choke pull off, no idea where it goes and I have added parts to my throttle pump that I don't know their purpose! ill try to post pics but not sure if I can. Need some help
