some 383 questions
 
so im about to start ordering parts and i thought i would ask you guys some questions. the rotating assembly that i want to order is an Eagle 4340 forged crank, Eagle H beam 4340 rods and Wiseco -3cc flat top pistons. will this be a solid rotating assembly or should i step up to K1 crank and rods or maybe something else. also i have ideas of running 11:1 compression ratio. what do you guys think of my bottom end?

Sounds like a solid bottom end I used an eagle rotating Assy in my 383 build and love the way everything went together, a buddy of mine ordered a 383 from cnc motorsports that used the same eagle rotating Assy I used and is running strong in his scca car making just over 400 rwhp on 93 octane at 11:1 comp.

well that is some good news. im hoping to make a bit more power than that but i dont know if its possible. i was reading an article in Car Craft that had a 383 making 595 at the flywheel.

it sounds good to me
i believe eagle has stepped it up a notch or two
in their quality in the last few years.

dont forget to balance the assembly
:angel:

the shop thats boring out my block will be balancing it as well. i guess the next step is figuring out what heads and cam would best fit my engine and truck.

im guessing a highway commute to work every once in a while will be interesting then.
