Cam headders and a... monojet?? idk

[Jake's 72' blazer]

Hello chevy fans. I have a 72 blazer with the 250 l6. 3 speed on the floor. it has a mild cam and headders and a 4 brl offy intake. bored .30 over with new flat top pistons. it had a 2 brl holly adapted but it had fuel issues. i found a single barrel intake here at a local bone yard. now i am thinking of getting a new or remanned monojet carb for it. will this be enough to run the truck? i dont need performance just want it to run and hopefully last. thank you. any help is much appreciated.

I had a 3/4 ton 70 2WD with a stock 250. It moved pretty well, but it had 4.56 gears in it. It was done by the time it got to 60 MPH or so.

The Camaro I just built with my son has a 250 in it, and I was surprised how well it moves the car. The Camaro is quite a bit lighter than a Blazer, though, so I don't know how that will compare.

but would a new 1 barrel carb be ok for my engine?

A one-barrel is what my 70 had on it.
