Don't read if you're close minded
What find funny about this over carb debate is even the people that push smaller carbs generally over carb themselves, just about no one uses what the formula recommends, (cid x rpm / 3456) x VE% = carb cfm @ 1.5" hg.
A basic 5000 rpm peak hp 360 probably around 85% ve = 443 cfm
Same spec 318 = 390 cfm,
same spec 273 = 336 cfm
". 225 = 277 cfm
". 170 = 209 cfm
How many under 500 cfm 4bbl option are available to us ? Seems like the carb industry believes in over carbing.
Even a similar 440 = 541 cfm which is 59 cfms smaller than the standard 600 cfm carb that's recommended for mild small block applications.
Even if we crank hp peak to 6000 rpms @ 95% ve it raises up these carb cfm numbers 34% eg. 360 = 594 cfm that's a pretty healthy 360 (450 ish hp) and all that is recommended for is a basic 600 cfm carb so 90%+ 360 and anything smaller are pretty much over carbed, even a 440 @ same specs = 725 cfm less carb than most would run on milder smaller V8's. If 1.5" hg is the goal most of us are over doing it.
