Re: 383 kits?
The low cost 383 option is to find a SBC 400 crank (which is not easy find or cheap) and have the main journals of the 400 crank turned down by a crank grinding service to fit the 350 block (which again is not as cheap as a standard -.010 / -.010 crank grinding service fee). Using the SBC 400 rods (which I have a real personal dislike for) and stock 350 pistons would be the least cost piston / connecting rod combination. All the other piston / connecting rod options for building a 383 are going to be more expensive.
If your engine building budget is limited, then building a 350 is best dollar for horsepower option. I don't mean to butt heads with the "there is no replacement for displacement" engine builders. I've seen several 350's with aftermarket heads, make more power than a low cost built 383. My personal opinion for a budget built performance SBC 350, is spend extra money on aftermarket heads (like World Products SR's), an aluminum intake manifold (like an Edelbrock Performer) instead of an extra 33 cubic inches.
