use the cast crank until you can get the aftermarket block. the block will let loose before the crank gives. i would also at the same time as the block purchase get a internally balanced crank and loose the 50 oz weights on the dampener / flywheel at the same time

I've seen a few forged 4340 50 oz cranks before. I'm just having trouble finding one now. Its like a unicorn. Or is not worth using one if I find one?

 

Probe, Eagle, Scat, Callies, probably all have them if you did a quick search. Anything forged 4340 will be as strong as you will need.

 

Here is a link to SCAT and they have 6 of the standard weight (assuming this is 50 oz balance) cranks as the first ones that pop up.

Oh trust me I've been looking for a while now. I believe most companies quit making them in 50 oz external weight. I know they have produced them before but I'm having trouble locating one. Going this I'm trying to save money not buying duplicate parts.

 

Well it is your lucky day, there they are. Just give them a ring to confirm.

 

Brian at AD Performance could probably hook you up as well. He is great to deal with and knows what he is talking about with this stuff.

I did take a look at them and not sure what standard weight is. I can give them a call tomorrow.

 

Stick with a stocker until you go with a dart block. Then go with an internal balanced setup.

 

std weight doesnt mean 50oz. A newer scat can be balanced to 50oz, but you will be removing alot of weight depending on the bobweight. An older scat or one with a part number ending in "I" will be a alot of work balancing to to 50 as you will be remving a ton of weight. An eagle, or rpm internal balanced to 50 would also be ridiculous.

 

What does it mean, actual stock weight crank? I noticed there is no balance mentioned with them as well. I just assumed it meant it was a stock replacement with the correct balance. Thanks

So Mr. Woody is it worth balancing the crank. Or should I cut my loses on the new components I have?

 

I wouldnt do a 50oz balance to any of these aftermarket cranks. If you have brand new components, never used I would look at returning them or selling them and losing only a little bit of money.

 

Okay so I think I might have to suck it up and take the loss. Maybe put in some over time. Just out of curiosity does trying to balance the crank to 50 oz affect its integrity? Also during my search I came across some older Hawk 4340 cranks that were balanced to 50 oz. What was the deal with those?

 

You can balance cranks to 50oz, they may end up with 8-9-10+ 7/8ths holes drilled in them because you have to remove so much weight from them because all the weight is on the balancer and flywheel.

Hawks never made cranks, usually chinese no name cranks. 50oz is not good, nor bad but certainly not preferred by any stretch.

 

Woody, do you still sell fully machined stock 5.0 blocks? I remember seeing them on your website in the past, but not any more. I ask because my son is doing a 306 and he will need to have his block machined or get one already machined.

 

Email my wife nicole@fordstrokers.com. we do them but don't advertise it anymore

 

Thanks! Will Do!
