Then the icing on the cake to kill the project was when I asked Eagle Cranks to make me the same crank that they made for ______ Engine shop and then **** hit the fan due to an Eagle employee making an under the table custom crank....[/Quote/].
Too bad you caused the turmoil Sean.
I see Bill checked in the forum August 16th, this year, no postings though. He must still be 350 sbb curious.
I wasn’t the one causing turmoil I spoke with Bill on the phone about the whole fiasco and it was another member of our forum that was rude when talking to Eagle about the cranks. I simply asked about the crank and when they said I would need to pay $3500 in research and development costs I simply I went to King cranks and started from scratch. It was another member of our forum who went on a tirade being rude to people with Eagle about the deal. Anyone who knows Bill can ask him he knows that it wasn’t my fault.
I called king abt a crank 4 months ago. They said 6 month wait. As long as ive been dinking with this stroker, I shoukd have ordered one. IIRC it was abt 2,5k
Yes it’s a heck of a lot cheaper for you guys to get a King crank now that I paid the $ to get the reaseach and development done so now it’s a lot less time and $ did the public to get a crank. Plus a simple key strike and you can order a crank with a smaller rod pin diameter and longer stroke. They feel we can go with Honda journals and stroke to 4.00 and still be good for 1500 Hp... that is if you can keep stuff from hitting other stuff...
That is only .010" more(.005" per side) than what people are stroking the factory crank too now that they make work.
I would be more interested in a 4.250" stroke with the 1.850" rod journal size. A forged billet crank wouldn't care what the stroke is if you wanted to spin it to over 8,000!(as long as the other parts are up to the task)
With a billet reduced base circle roller cam and some custom 2.0:1 rockers, I'm sure there would be plenty of clearance for my needs.
Yeah they would build the crank with 1.5” rod pins if that’s what a person wanted... they do double cryo treatments and top notch materials so I’m sure even a small rod pin would be way stronger than a factory crank. They even ship them out internally balanced to your bob weights.
The smallest I would go would be the Mitsubishi rod journal size of 1.771", basically 45mm. That is if I could use a rod that is only around 5.900" because that was the longest off the shelf Mitso rod I could find, don't really want to make customs either. I don't really like the idea of using that short of a rod with that much stroke so I think I would stick to the 1.850" size.
So how much would a king crank be now? Stock spec. For example.
See post 67.
Should be about $2100-2400 for the long billet crank. A lot of my cost was reasearch and development fees.
550h.p. n/a with only 8.5 comp, whoa..... you'd think 10 + plus would be needed.
Is 1.850" stock Honda? What are the NASCAR t/o's or do they vary?
Not sure if the 1.850" size is a Honda size or not since my bearing catalog is from 1996. I do know the 1.889" size is used by Honda and Toyota though.
I'm drawing a blank on "t/o's", can you write that out?
Nascar take out rods.
Yes the t/o's vary, I have seen them from 2.00", 1.889", 1.850" and possibly other sizes that may be out there?
I was told by an engine shop owner that the smallest that nascar can go is 1.771" on the rod journal size but haven't ever seen any that small.
Thanks Derek. I've been enamoured with the idea of using these rods since 1st reading your suggestion a while back. I did a pretty decent 350 build back in the '90's (ran 13.0's in a GS) and got out of all this for a while - Always thought it was a great engine if we could only get parts. Hope to do another couple 350's for GS's I now have (both need resto so just planning for now) and been reading all the threads. I chime in once in a while. Stroker with a roller cam, alum. heads, SP, & maybe a billet crank if $ allows sure sounds fun.
