Could this idea work ? Did other guys did this ? 318 infos

Thank you, on other opinions this 350 cfm carb could make me loose some low end torque as i read on other sites...my 1st idea was to be conversative and make the little 318 breathe a bit better with some better tiny flowing heads / better carb ( cfm ) and headers etc...i just didnt want to spend a ton of $$ on a 4bbl carb since i have 2x bbds and this one laying around

Are we talking part throttle or full throttle ?

On a full the throttle run what an engine makes under 2500 rpm really don't matter much you spend almost zero time there. Even half throttle makes 80% power of full with similar curve.

Look at the dyno run of the article on my post with cam and 4bbl there was about 50 tq gain at 3000 rpm, even at 2000 rpm which it didn't show I guarantee the modified was still making more, at least on par. It's good to be little conservative but power comes from air flow even down low, this idea you got to strangle your engine to make torque has never been shown on a dyno.

The idea on a street performance car where gearing and stall is gonna stock/mild side is to increase your powerband rpm range idle to 4500 rpm say to 5000-5500 rpm on top without moving to far away from idle where gearing and stall will be less than ideal. Which could be 100-150 ish hp gain
