crank choice
 

13-1 compression, 10-15lbs boost, alcohol fuel

Scat 4340, eagle 4340, gm forged ??

this is for a spare motor, I don't have the fuding for a crower, moldex, bryant,,,,

Ok, I'll bite...
13:1 w/ 15 lbs of boost on alky. Sounds like you really should have the Crower, Moldex, Bryant, etc..

Ok, bite #2

Is it a big block, small block, ford, chebbie?

How big is the blower, IE: b/blk or sm/blk, rpm range? From what i've been reading Scat has a better handle on the inspection, although both cranks are the same varity (Chinese)
I've run both in sm/blks with good luck (so far)

Zip.

BBC tall deck, 8/71 with striping and anodized. 6000rpm max on this one.

Anyone have experience with this brand?

A friend of mine has one in a 526 blown big block chevy. Oddy dynoed it at 2200HP. He has ran it one season so far in a rail buggy.

TS1955 which crank the Ohio 4340 or their billet?

Same as the Eagle or Scat in the 4340 version ( Chinese imports) although the Billet may be American made.

Here is a couple good reads on crankshafts, i realize they're talking about Chrysler cranks, but incluces all the crankshaft companies.

Callies Dragon slayer would be just fine for you. USA Made
Depending on your stroke they start at $1050.00

Anything cheaper than this is a Chinese crankshaft

Read this forum on the dragon slayer cranks. USA machined, not forged.

i too had bad luck on an eagle crank but it was there cast replacement it was the roughest looking crank i have ever seen, i use the howards cranks they are true american and they have callies do all there work and it is a very nice peice and i checked them all before use and they are very acurate

Hey bigcrunch...I talked to my friend and he said that he has a billet shaft. He has the motor apart and everything "looks" OK. But he is getting ready to take his stuff to Oddys for inspection.

ts1955, thanks for checking the billet Ohio crank priced under $1k might be a good deal :)

My bad, they are actually imported from Japan and 100% finished by Callies. Callies fells like it is the strongest forging on the market, besides for buying billet.

After my EAGLE crank broke after 150 street miles, I bought Ohio. Eagle WON`T stand behind their product. I wouldn`t reccomend Eagle at all. I have a 500 dollar Eagle door stop now! :lol:
