I've been bitten by the stroker bug.
Anybody have a stroker crank and rods they'd like to sell?
My current thinking is to use OEM pistons with stroker crank and rods to build a 6.0 engine.

Your the second person to say that. Mark was the first. I read a bunch of stroker threads and I swear that combination was mentioned.
Clearly I was wrong. Moving on.
I have collected some bits recently. Among them are 8 968 pistons and a couple of superchargers Rotary and Twin Screw. I have an 86 and 87 engines, too. And I know of a GTS crank, too.
Mark suggested boring the 86 out and using the 968 pistons and a stroker crank. That's my new direction.
I would be happy with a 6.0 that I can toss a twinscrew on. :-)
Thanks for chiming in. Maybe you haver a stroker crank gathering dust? Hee hee.

It's really expensive if it's not done correctly. After living thru GB build mine and I'm sure Jim Coreman and Rob Edwards etc, can add to this, it's not just a matter of bolting bits together. Everyone has to be in concert, the shop that builds the block with the crank building, to Colin ( don't forget the cams), everything has to match the design direction and there is a lot of dialog that goes with it.

The plan is put a set of bits together to have it built. I don't need a 6.5ltr stroker to be happy.
This will be an odyssey of sorts - no telling where it'll end up. Just scratching an itch.

Yes, I do try to keep pieces in stock....

Ok, so I think this was Jim's engine details according to a thread back in 7/11/16
It's 5.9 liter (104mm bore, GTS stroke) high revver- light crank, smaller rod journals to decrease bearing speeds, Nikasil/CP pistons, higher compression (gonna need some race gas per tank), welded/reground GT cams, DLC'ed lifters, Greg's intake, fuel and timing by Alpha-N, and Mark's old Tri-Y headers. Same heads as the old Zombie motor, with a little more attention paid to the ports and chambers.
That sounds interesting to me. I'd like to use the 968 pistons I have on the shelf and either have a GTS crankshaft modified or buy your lightend version. There's no mention of the rods he used. So, I need to fill in some of the blanks. Jim started with a '90 GT engine. I haved a couple of S4's that I'd like start with. I know I have read that S4 heads on a S3 has lower compression and I really like the look of the S4 manifold. So, that may be a non starter.
What I would love is a stroker summit on the east coast - perhaps at SITM in June where we could have all the great minds together on a panel to discuss all this. What a great wasy to celebrate the 20th SITM!

If you have a set of 968 pistons in good shape then that is a big first step. Rods need to be custom pretty much whatever you do.

That is Rob Edward's build for a new motor for the Zombie, Mark Anderson's race car. Our GT is similar, except factory 968 pistons and Alusil rather than custom CP pistons and Nikasil. Crank is Greg's GTS-stroke, rods are Carillo, compression is around 10.5 I think, intake is stock (ported), Devek headers and dual 2.5" exhaust. It is a very sweet engine.

"factory 968 pistons and Alusil" This looks like where I'm going to head. I assume we are talking about bore/hone an S4 Alusil block to match the 968 pistons. You mention porting the manifold. What did this entail (without revealing any secrets)? What else was in the build? Larger valves? Head porting? Camshaft specifications? I assume racing chains and valve springs and Greg's headers and exhaust and Provent oil separator a bunch of Greg's other goodies.
