D4b or not to D4b

What are the gains on a 64/65 273 if I swap out to an edelbrock D4B?
Engine is rebuilt with correct 64/65 stock 4bbl intake. Paperwork said it has an "rv" cam.
Car is just going to be a cruiser on weekends and to shows.

It will come off the line stronger and get better MPG... The D4B will give more low end and mid range than the stock intake and will also have good high RPM pull...


That will run great on your engine...


Do it... :thumbsup:
