This is for 340 builders

I dont plan on racing it. I'm not going to make it fast, 12 to 11 second in the 1/4 is all I'm going for. Combression around 9.5 to 10:1 max.
This car is stock other then the motor and wheels. Looks like it came from the factory and placed in a barn for 17 years in Washington. The only thing missing is the stock gas cap and the H in Plymouth on the hood.
So since I do not see many 66 Cudas here , I will build it to look stock. I'm going to make a sleeper. I will try to also keep the engine looking stock as possible.
The part number on the rods is 3418645. My books show this as a 74 - 80 318 forged rod or a 71-80 360 forged rod. Still loking for the number on the crank. The crank is forged due to the 1/2" wide forge flash. Cast cranks have about a 1/4" wide cast parting line.
I"m really getting good info here on these part swaps. I feel good about the crank. Still not to sure on the rods. The information I found out on the rods I haveis that they do not have any offset, but 340 rods have a .100 offset. Also the rist pin is .0362 smaller then the 340. The center to center length is the same.
I dont have any info on rod beam thickness for the 340.
I want to stay with steel rods, will get some nice flat top pistons with valve reliefs. Has any one used pistons from Eagle?
Thanks for all of the good info.
