Forged Cranks

who has the most reasonable priced Forged Cranks for a BBF in the 4.30 or 4.50 Stroke, Do not need a billet just a good 4340 Forged crank

Explain REASONABLE price vs. quality wanted.

under 1000.00 but stronger than a scat 9000 crank, and one i do not have to put 5 pieces of heavy metal in.

thanks for the information, do they have a website

Call Adney and talk to him. He's a great guy and has probably forgotten more about crankshafts than most of us will ever know. Great workmanship and good prices with service after the sale. Don't just blindly buy a crank off of some website, call the man. You won't be sorry

X1000 on what has already been said. If you're not getting the hint, he's the "Crankshaft Man".

think i got the hint, i will call him Monday

Dave, you "typo-ed" his area code. It's 586 .

Use a SCAT 4340 forged steel crankshaft...

X2 on ALL of that

Adney told me today, someone on this site or the old one did an article on balancing one of the scat forged cranks, can someone post a link or send it to me, i did not catch the name i think it was don, i will call him tomorrow if no responses thanks for the help got a new 4340 Crank and some coated bearings on the way.

Adney won't do you wrong, he's top notch.

i had almost 5 #,s removed to balance my 4.3 with the BME aluminum rods and diamond piston combo

here is a link from when Adney and Dave built this engine from the EMC ........

Adney told me the Article was written by Damon Sea, He is going to try to email it to me I will post it up if i get it.

Fixed it

'Er, that'd be Damon Sea.

that was me, It's in my engine build thread. I'll go get the link...


Here it is, my engine build thread with the Crankshaft information

BTW: I like my Performance Crankshaft Custom Scat 4340 Crank

4.310" Scat 4340 Forged Crank is getting balanced. My bob weight is 2235 grams so Butch informed me that he needs to remove 220 off one end and 210 on the other end. Instead of making the throws look like swish cheese he's going to set it up in a lathe and take off .050" from all of the counter weights and then check it again. It may take as much as .100" to get it close. Will keep you posted.
Nice looking Forged crank Thanks to Lem for the technical advice and Adney Brown of Performance Crankshafts Inc. for the crank

[quote=hookedonpullin]I'm just a little curious as to why its a 4.31 stroke crank. Is that a custom unit? Thanks[/quote]


Yes, it's Kind of custom.
I didn't want to zero deck my new block but I didn't want a BIG quench area either. SO a compromise was reached by decking my block to 10.315" instead of 10.310" and then just adding .010" to the stroke so now my piston to deck height will be .010" and I didn't have to cut the crap out of a new A460 block
Thanks to my technical advising team for this trick
FYI My Compression height on my pistons are 1.350" If I had ordered new pistons instead of finding these JE pistons at a good price then I would have just ordered pistons for a 10.320" deck height and just skimed the top of the deck.
Hope this made since

More information about balancing the Forged Scat Crank.
Some hidden costs about balancing that I learned the hard way. i.e. It may be more economical to have the forged crank balanced at the vendor i.e. AD Performance, Performance Crank shaft, River Racer etc...... Get your bob weights from your machinist and then give that information to the vendor. I had an additional $200 in machining added on to my crank for 4 hours of lathe time to cut weight out of the crank throws in order to make it balance:
Here's the weights from my balancing job. 4.310" Scat 4340 Crank with 6.8" Eagle H-beam rods L19 bolts, JE Flat Top 4.44 pistons

Rod (Big End) 525
Insert 55
Total 580
Times Rods/Throw 2
Total 1160
Oil 4
Rotating Weight 1164
Piston 602
Pin 174
Locks 4
Rings 57
Rod (Small End) 234
total 1071
Times Pistons/Throw 2
Reciprocating Weight 2142
times 50%
Each Half 1117.5
Recoprocating Factor 1071
Bob Weight 2235
Here's the balance notes:
F = Front
R = Rear
Start: Remove F 220 R 211.
Put in lathe & removed .070 from all counters
F 129 R 146
Took .050 off front 3 and .075 off 2 rear ones
F 51 R 63
Took .060 off #3 counter & .040 off 2 rear.
Needed to remove 29 grams from front and had to add a 3/4 X 1.120 piece of Heavy Metal to rear to kick.
Then was 29 to remove in front & 32 to remove in rear. Drilled to balance
F .2 R .1
Now the moral of this story is that my rods were a little lighter than a typical 810 gram H beam rod so if you plan on running an aluminum rod or lighter piston/rod combination then chances are you will need to cut a lot of weight out of the crank.
Hope someone learns from my error
Here's my crank after it was cut and balanced. Looks NICE now

Thanks due to this Article ADNEY got to balance my crank called him with the weights today

Recived 4340 Forged crank, coated rod and main bearings everything looks Good
