Hey Mike S., I could have used a good set of pistons whan I started collecting parts for my 383. I am building a high revving 383 and had to use KB400 pistons. All machine work has been done. It is ready for assembly now. Finding good aftermarket rods are also a problem. I set my 383 up using the following specs:

My target with the KB pistons and stock rods is 450-500 hp at 6500 rpm.

KB400 +.040 pistons
Reconned stock rods w/ARP wavelocks. (Couldn't find any Eagle 383 rods, the supply of them is quite sporadic)
Steel crank
5/64 moly rings
Clevite bearings
Balanced spinning assembly
Mopar .528 Solid cam for initial start up and engine break in (Muscle Motors has spec'd out a custom Comp cam for me that I will use after I get the car and engine dialed in)
Stealth Heads w/Muscle Motors blueprinting and Stage One porting with 83cc chambers.
Edelbrock RPM intake
Biggs 750 vacuum carb.
MSD ignition

I understand the business need to start out with a stock rod 383 piston. But if you get this off the ground and can expand your line then I personally would like to see a set using the plentiful and inexpensive .990 long rod with floating pins and 1/16 rings. When they are available I will be the first in line.

I hope you can make this happen,
Mike F.

P.S. The car is a 1964 Dart with a Hemi 4 speed, Dana 60 w/4.10 gears.
