Re: RV8 Custom crank, how much spigot ?

Clan, Ford raw forging will make 3/8" min. on spigot length. Is this enough compared to late cranks at 5/8" approx ? Scat needs to know. Onward, roverman.

To All;

Yes we can make a crank for that engine. That's basically the same engine that is used in the Land Rover, isn't it?
Cost is $2800 with about a 12 week turn around time. Let me know if there are any special dimensions (journal sizes etc) that you need.

Regards, David Eden

William - Thanks, that's interesting. If I have one more delay by the people I've ordered from, I'll be cancelling my order and giving these people a ring.

Julian and clan, I seem more likely to win the Lottery here, than get a crank out of Scat ! 5 months and nothing ! Good news is, I spoke to David Eden. He seems knowledgeable, and they have made these cranks before. Being within driving distance, is a plus. roverman.

Art - 5 months? 5 months is nothing, they work on the geological time scale. I've waited 10 months for a quote.

Backwards,

Julian

I spoke to "Tom" at Scat. They have hired (3) more enginneers and are catching-up. I am to check back next week. Ford 302 raw forging, has better suited counterweights than Windsor, and has a stroke potential of 3.5-3.55". Onward, roverman.

According to Scat, sbf raw forging will not work ! Luckily, Mickey Thompson and Lance Reventlow, didn't "Know" this. Scat will make a billet crank for $2,800, in 8-10 weeks. roverman.

Re: RV8 Custom crank, do a 180

So, 4340 billet steel cost from 32.5cents/lb.,(China/1 ton min.), to $6.60/lb., local for 190lbs. Water jet the profile-unknown. Considerable hours of labor, without millions of $'s of equipment, is a given. Onward, roverman.
