383 Stock Stroke Build

Hey guys, finally getting parts flowing for my build, I was really on the fence about doing a 360, or a 383. I chose to go with a 383, I will save the small block parts for another day. I will get pics up as soon as parts start arriving. I am waiting for the rods to show up before I take the block to machine shop. I am building on a 1968 383 with a steel crank. I decided to go with 440 length rods for the simple reason that they are readily available, in stock everywhere, and are available with .990 pin. Rods are Eagle P/N CRS6760B3D. I will be using Diamond Pistons P/N 51907. At this point I am not sure what the final bore size will be. For a small fee, Diamond will move the piston pin to your desired specs. The plan is to have the block square decked and remove as minimal material as possible, then order the pistons with the necessary compression height to place the piston at zero deck. I ordered a cam and lifter kit from Lunati, P/N 30230740. Specs are 235*/243*, .526"/546" using a 1.5 rocker arm ratio. I will be using 1.6 Crane, Ductile iron rockers. I originally was going to stick to 1.5 ratio, but 1.6 was all they had on the shelf at this time. Theoretical lift will be .561"/ .582".

Now, for the part that I am most excited about, I ordered a set of prepped 440 Source Heads from Jim LaRoy (IQ52), he is going to do his normal prep work to them, install beehive springs for my cam, and install tool steel spring retainers. He is also going to mill the heads to get the chamber size down to 75cc. A 75cc chamber will put me right over 10:1 compression ratio with stock stroke, and flat top piston. He is also going to clearance the push rod holes to clear the 1.6 ratio arms, and 3/8" push rods. I am really really excited about these heads.

I don't know what intake I will be using just yet, I am open to suggestions, as long as it will fit under the stock hood of my '73 Duster.

I have no realistic guess as to what power will be, but I hope it is a lot of fun.
