SBF crankshaft
 

I am trying to figure out if there is a replacement crankshaft list for super stock. I see there is one for stock but I am not seeing one for super stock. Thanks for the help.

Thanks,
Jamie

How about Forged steel Boss 302. The non cross drilled 70 crank is the best of the two.

Re: SBF crankshaft
 

They are the same. If it is legal in a Stock eliminator engine, it is legal in a Super Stock engine. All aftermarket cranks for SS must be like an OEM crank, so no billets (unless factory equipped), knife-edging, excess lightening, etc. There are only two SBF cranks accepted at this time, the Eagle 430230005090FD for the 302, and the Accufab for the 5.4 modular motor.

The following NHRA link says what is allowed in a Super Stock class crankshaft:

The 69 Boss 302 and 70 Boss 302 cranks are not the same!
69 is across drilled hollow rod pin and 70 is not cross drilled! 2 different part numbers. You don't want to run cross drilled above 8000 rpm.
Been there done that!

You Have a PM .. I have what You Need .....Thanks !!

I contacted Eagle about this part number in 2014 to see if it was available and they told me it had been discontinued around 10 years ago. Eagle's current forged crank for the 302 is part number 430230015090, As of an email in 2014 they said they had given up trying to get NHRA to approve it.

Difficult to find perfectly clean and legal forged cranks for SBF.

Lots on the market, none on the list. Go figure.

The 430230005090FD crank is a Eagle Forged 4340 crank made for Ford and sold under the part # M-6303-E302 crankshaft. It is the 302 internally balanced crank used in Ford's crate motors. Hollow rod journals, nice piece. They are available for less than $300. I think it's the best best deal out there for a forged Ford 302 crank. Still available! Shop around!

Re: SBF crankshaft
 

M-6303-E302 is no longer available - the last one left the warehouse in January 2015. There may be 1 or 2 sitting somewhere. It was a smoking deal while it lasted.

Re: SBF crankshaft
 

Two new on Ebay right now, many Ford suppliers sell them. Roush Yates stocks them and sells them for 289 w/free shipping. There are plenty around...how do I know...staring at two I had stroked .013 yesterday.

Re: SBF crankshaft
 

The E302 mentioned is listed as being for 83 and newer blocks. What engine build are we talking about in this thread?

What is the stroke difference between an older build like the 68 Cougar 302/230 I'm trying to get legal and the 83 and newer blocks? I run the M-6010 BOSS 302 block.

Re: SBF crankshaft
 

The 1983 and newer are one piece rear oil seal. 1982 and older is two piece. The stroke is the same.

best regards,

Re: SBF crankshaft
 

Thanks. The Eagle I wound up with was listed as either one or two piece seal. My block, which is accepted for all SBF applications, takes a one piece.

Submissions by racers carry more weight than mfrs' requests.

Re: SBF crankshaft
 

According to the form at NHRA Racer, I have to ship the crank to Indy for approval. Can't do that now.

Re: SBF crankshaft
 

Dale,

Approval for cranks usually only needed photos from multiple angles and specs, I have sent pictures from a manufactures catalog along with specs, weight, journal diameter..material...and received approval. Piston and rods...different story.

Re: SBF crankshaft
 

Hey Brian...just a note...called Roush/Yates day after your last post...March 9th (live couple miles away here in Mooresville)...spoke to Carl...nice enough...he told me they were out...(?) for some time (!)... am not a e-bay guy...any other ideas?...thank you...for your time-Drake

Re: SBF crankshaft
 

Drake,

Did you check sriperformance. Roush Yates parts? I typed in their search the Ford part # M-6303-E302 and they still list that crank in stock. 289 plus shipping (used to have free shipping!) Try to order and see if it comes up empty, There were some Ford specialty guys who had them before.

PM me if you still struck out. I may still have my list of who might have them back when I bought mine.

Re: SBF crankshaft
 

I searched on this and here are my result with contact numbers. The first two list "subject to availability" while SRI, as Brian indicated, has a list price. Call them all.

One of the issues of web searches is that things continue to show up long after they are gone from the shelves.

AMP Performance 602-437-2727

Marken Performance 888-401-1362

SRI Performance 877-604-8077

Re: SBF crankshaft
 

If there are any of the cranks left it will not be many. I sold out of them a good while back. When Ford discontinues an item they provide great pricing sometimes. The deal right now is 302 Mahle pistons and ring kits. They are only available in .030" over and press fit.
