Attached is a picture I robbed, to show the stock intake level, once the engine (a 261) is installed in the truck chassis.

Just friendly advice:

If your 235 is rebuilt to stock, not high performance, the best carburetor is a one barrel Carter YF 2100S on the stock intake and stock exhaust....my opinion.
If you haven't already, do the engine break-in run with known good stock parts.
Once you are satisfied, swap over to the performance setup.
If the performance setup works better, you have bragging rights.
Post your results so everyone here can read about it.
