Who makes a forged externally balanced 383 crankshaft for a 1 piece rear main?
I've been looking for one forever and don't know if they exist.
I want to externally balanced because I've heard its just a lot easier then internally.
Thanks

 

Just go with the internally balanced crank with 1pc rear main seal. For the money, the Callies Dragon Slayer is very highly thought of.

 

I just got a whole assemble from EAGLE

Eagle 383 internally balanced assembly with 6.0 inch rods and SRP pistons $1200. part number 103523750L works awesome just remeber to take the weight off the lat model fly wheel. No vibration. I had to do some minor machining on the block maybe 1/16 near the filter and 4 spots on the drivers side where the rods came up. very happy with my setup. look at my cardomain page for pictures and info on what i have. good luck

 

I thought about a rotating assembly package, but none of the ones I've found have 5.7 H beam rods and forged pistons.
From what I've heard from a lot of people is that I should go with 5.7" rods because I'll be using a lot of nitrous.

 

lunati and callies makes great cranks from what i heard

GM's crank is 3.8 inch instead of the normal 3.75 but its really expensive at 1000bucks. not sure why its expensive compared to their other 350 cranks.

 

Check out http://www.speedomotive.com/ They seem like a good place. Awsome Tech articles also.

 

Im pretty sure both summit and trick flow make them for 383 1pc. seal. little pricy for trick flow but.
