But, it's calculated based on ft lbs of torque produced while running. Dynos measure torque, tachs measure rpm. The math gets done. HP is entirely dependanton two variables. The torque being produced, and the engine speed in RPM. It's a math thing.

Im terribly conflicted... Carbs
Here is an article dicussing Carburetor size and choosing the best one. They used a dyno and also checking vacuum readings. Choosing The Right Carburetor - Tech Articles - Classic Trucks Magazine

thats because hp that we think of is nothing more than a math formula..
not what that engine can do..
I'm willing to bet a 160hp engine can't pull 1/3rd what 160 horses could..
if it could you'd snap the chain(most front drive cars) or gear teeth everytime it shifted gears at wot at hp peak..

Ive also noticed something very intresting, what Techinspector has pointed out and many other dyno guys on this site, is on the kinda of engine were talking about and big block chevy,(idk if this is true for other engines like ford, dodge ect.) that at 5252RPMs peak torque meets horsepower. intriuging as it is id like to save that topic for another thread involving V.E and other things that could cotribute to this rule of horsepower and torque 5252 rpms

|chevy302builder18||Thanks for the responses, im definatly going with a 750 on my 406 cubic inch. it that doesnt make 87% V.E what other alternatives would there be?|

|vinniekq2||390 carbed roundy round cars used longer duration on the intake side.non restricted engines in the same cars made a lot more horse power. My slightly larger carb on my engine works well,even though I only use 3.5 gears and probably too big of cam in most peoples opinions|

358cids with 390 carbs, made so much power they added plates to slow the cars..
there is tons more to it than just stabing a 750 on a 350 and calling it good.

All I know is,
Alum heads, 10.5:1
It ran fantastic with a BG 650
I swaped to a BG 750
It went 2 tenths faster
Yes it gave up some low speed response.
But it went 1.6 MPH faster almost every time.....
