The 383 Build!
Theres not much to say about it other than its a lot stronger than a stock 350!
The crank is cast steel from Scat, the forged I-beam rods are also from Scat. the pistons are Forged flat top Speed pro pistons. The cam is custom ground (i dont know specs yet, engine builder does) the rest of the valvetrain is full comp cams hydrolic roller rockers and lifters. The heads are aftermarket Aluminum heads with 2.02/1.6 inch valves. Finally the intake is an Edelbrock RPM air gap.
Well, here are the pictures I have of the machine work so far, keep comming back for more updates!
Heres the lower end as it came when we purchased it locally for about $150
One of the cylinder walls had a gouge in it, and had to be sleeved
ready for line honing.

Edelbrock Performer RPM Q-jet came in, can also use a Holley carb.
Old engine in the car for the last time
New engine in its new home
While waiting for the engine to be completed i decided to make 383 emblems to put on the hood of the car, in place of the "L-48" emblems. I know they sell these emblems on ebay and such, but i thought itd be cool to be able to say "i made that"
First i carved the earnhardt 3 and 8 out of wax, then placed them into a form of latex so i could melt wax into it and re-create as many numbers as i needed.
I melted the 383 together in wax, and did some final shaping
The wax 383 was then placed into plaster, the wax was then melted out after the plaster set.
The plaster was first preheated in the oven for about an hour to get all moisture out of it. A mixture of tin and lead was then poured into the plaster.
After removing the plaster and shaving off the excess, heres the finished product, next is some nice black paint and some studs to mount it.
