383B Stroker Build

I just picked up a 1968 383 complete engine for 150$

I want to go stroker, N/A, raised port aluminum heads and run on pump gas with it.

First I need to figure out what stroker combo to run.

I see 440 source has 2

383>>496, 4.250
383>>438 3.750"

Why isn't there on with the 4.15 stroke??

Is it possible to put a 440 crank in this engine? I'd assume yes, just needs to be cut down right?

I'm all ears to options and recomendations.

First off, may I ask how much power you are targeting ?
and,
keeping in mind rpm is a function of hp, just what range you are looking at that hp ? upper and LOWER.

Because the Car is 50% of the equation.... and serves as the platform to run the Engine, things like Tire Diameter, Gearing, Primary Header Tube Size, Fuel System, Cooling System, etc., etc., must also be conduscive ?
just sayin.... and for example here,
in my world when guys start talking hi ports like the Victors on Strokers... more than capable above 600-650+ hp.... too often things like supplying "fuel" get overlooked. Just no way it can be supplied sufficient BTU's in Fuel through a 5/16" or 3/8" Line and stock Tank Pickup ?
or,
a 10-15% bigger Engine, at hp, can produce up to 30-40% more heat to cool in a tight engine bay ?

No matter, I am sure you will figure all that out.
Just wondering how much you are targeting with Victors on a Stroker ? .... and with the stock 2 bolt 383 thin web mains ?
