RV8 billet cranks ?
There is a skilled U.S. billet crank manufacturer, that would consider building min. (5), at a time. Serious only, please, and no chatter about how great the oem. cranks are, and they "never" break. This is NOT an ad. Cheers, roverman.

Re: RV8 billet cranks ?
IMHO,using 2.5" mains and 2.0/2.1" rods, to be a good plan. Using available rods,also good. Being billet, I'm pretty sure strokes will be "open". Of course the sbb folks will want 3." mains, and giant strokes. I'm sending a crank drawing, for bid puposes. Too early to fish with prices. Anyone can get a one-off billet crank made for 2,600-$2,800, if you don't mind waiting 8 weeks minimum ? This scenario, is to improve that situation. TBC, roverman.

Hey Larry,
I have a 78 308 GTS. It does vibrate/resonate at various rpm's. But nothing that would be found to be objectionable. It is a pretty short stroke engine so that needs to be taken into account. Art, I'd be in on a large journal crank. Something in the 75mm stroke range. Fred |

Re: RV8 billet cranks ?
Fred, When you say LARGE journal, really 3.0" ?? 75mm = 2.953". Sounds like a "spec 32v. engine"? Jukka, I suspect most folks will want 3.4"+ strokes ? A 180 crank, with a large stroke, will prove problematic/impossible for one wearing dentures. If you "need" a roller cam for a 180 crank build, I have the blanks. Likely to be 500-$600. US. Let's talk journal sizes, long vs short snout, and strokes. Onward, roverman.

The large journal Rover engine 63.5mm/2.5'' Art.
