Brent, any update on the flat plane crank motor?

As of right now, I'm still waiting on the crankshaft to come in from Winberg.  I have two billet cranks on order, one from Winberg, the other from Bryant....about $10000 in two cranks.  I ordered the one from Bryant last year, they told me 24 weeks.  I'm still 6-8 weeks out on that one...

Heads are ported and assembled.  Intake is ported.  Cam is here, lifters are here, pistons are hung on the rods, rings are filed, etc.  Just waiting on a crank.

Was around some gearheads last night and that engine came up. The masses are itchy for hearing the melody that thing will sing.

Any chance there will ever be enough interest to get several of the flat plane cranks made for interested parties?

Do you think there will be any issues as far as reliability with this? I know there are other flat plane crank v8s, but almost all are much smaller displacement.

The cranks are stupid expensive.  Unless someone starts making them at large quantity, you're down to a $5000 billet crank.   And to be straight up honest, I don't know if there are enough pros to even warrant it.  I just wanted to try something new. 

I think it will accelerate very well, just because the crank will be so light.  But as far as making more horsepower, etc., I don't think there will be any advantages there. 

This engine will use a 3.5" stroke, with pretty long aluminum rods with Honda rod journals.  All one-off stuff.

Still curious about your project, any update?
