On a Mopar 383, the PCV (Positive Crankcase Ventilation) port from an Edelbrock carburetor typically connects to the driver's side valve cover. This helps in ventilating the crankcase by allowing gases to escape and be directed back into the intake system for combustion. Ensure that the system is properly sealed and that the PCV valve is functioning correctly to maintain optimal engine performance.
Answer I HAVE A 381 STROKER IN MY TRUCK AND I TRYED A 670 HOLLY AND IT WAS NOT ENOUGH I HAD TO AJUST ON IT ALL THE TIME ,I WENT TO A 750 EDELBROCK AND IT RUNS GREAT.750cfm, vacuum secondaries. also add an additional vacuum canister. you will not have brakes under hard accelleration if you have power brakes. the 383 is notorious for not creating normal vacuum. Answerdefinetely Edelbrock 750 cfm carb If it were me i would get rid of the junk edelbrock carb and get a good 670 cfm holley street avenger carb that's more than enough carb for a sb 383 up to 550 hp
without swaping heads or getting head work done your looking at approximatly 400 hp depending on the cam and intake and carb match.
The 1968 had 1 of 3 engines a 383 2 barrel carb, a 383 4 barrel carb, or a 440 4 barrel carb.
361, 383, 400, 413, 426 wedge, and 440 are all the same block as far as I know.
With the 318 ci 2 barrel carb engine, 1,134.With the 383 ci 2 barrel carb engine, 307. With the 383 ci 4 barrel carb engine, 178.
mopar 361, 383, 413, 426, 440, or the 426 hemi.
That's what they do. maybe check carb settings and such.
its in the center rear of the engine. There are 2 ports in the block, the sending unit is usually toward the left(drivers side) on a angle.
I am running the exact same combination with 0.035" gap. Good results.
I would depend on if you are asking a Chevy man or a Mopar man. Personally I like the Chevy 350. If you are referring to a Chevy 383 made from a 350 block with a 400 crank, it would always make more torque than a 350. So if torque is what you're after, "there's no replacement for displacement".
A typical carburetor size for a 383 cubic inch Chevrolet engine is usually between 750 to 850 cfm (cubic feet per minute). The exact size can depend on the engine's specific build, including factors like camshaft, heads, and intended use (street vs. race). For many street applications, a 750 cfm carb is often sufficient, while performance builds may benefit from an 850 cfm carb for better airflow and power.
383 as a fraction = 383/1 383 as a percentage = 383 * 100% = 383%
