After working on my interior all afternoon I just had to walk down to the store to restock on beer. Can't seem to be productive on the car without the magic elixir!
As for bore and stroke... I haven't had enough yet to go there.

You guys and gals should be right at home at our local biker bar named after the combustion engine, The Suck Bang Blow

Boring numbers:
Factory options
Bore / Stroke = Displacement CC / CI
95.00 / 78.90 = 4474 / 273 = 4.5L stock size
95.50 / 78.90 = 4521 / 276 = 4.5L 1st oversize
96.00 / 78.90 = 4531 / 276 = 4.5L 2nd oversize
97.00 / 78.90 = 4664 / 285 = 4.7L stock size
97.50 / 78.90 = 4713 / 287 = 4.7L 1st oversize
100.00 / 78.90 = 4957 / 302 = 5.0L stock size
100.50 / 78.90 = 5007 / 305 = 5.0L 1st oversize
100.00 / 85.90 = 5397 / 329 = 5.4L stock size
100.50 / 85.90 = 5451 / 333 = 5.4L 1st oversize
944S2 or 968 piston + stock crank
- Block needs to be specifically selected 5.0 or 5.4 as many do not have enough material from more than 103mm bore. 4.5 or 4.7 do not have enough material for much more than 100mm bore.
- Rods needs to be custom parts to get piston to block level at TDC.
Bore / Stroke = Displacement CC / CI
104.00 / 78.90 = 5362 / 327 = '78-91 crank + stock size
104.50 / 78.90 = 5414 / 330 = '78-91 crank + 1st oversize
104.00 / 85.90 = 5838 / 356 = GTS crank + stock size
104.50 / 85.90 = 5894 / 360 = GTS crank + 1st oversize
Common 95.25mm (3.75") stroker crank
- Block needs to be specifically selected 5.0 or 5.4 as many do not have enough material from more than 103mm bore. 4.5 or 4.7 do not have enough material for much more than 100mm bore.
- Rods needs to be custom parts to get piston to block level at TDC.
- All but 968 pistons will very likely require skirt modification to fit in at BDC, earlier the piston more skirt needs to be lifted.
Bore / Stroke = Displacement CC / CI
95.00 / 95.25 = 5401 / 329 = 4.5L piston stock size
95.50 / 95.25 = 5458 / 333 = 4.5L piston 1st oversize
96.00 / 95.25 = 5470 / 334 = 4.5L piston 2nd oversize
97.00 / 95.25 = 5631 / 343 = 4.7L piston stock size
97.50 / 95.25 = 5689 / 347 = 4.7L piston 1st oversize
100.00 / 95.25 = 5985 / 365 = 5.0 or 5.4L piston stock size
100.50 / 95.25 = 6045 / 369 = 5.0 or 5.4L piston 1st oversize
104.00 / 95.25 = 6573 / 395 = 944S2 or 968 piston stock size
104.50 / 95.25 = 6535 / 399 = 944S2 or 968 piston 1st oversize
There are obviously other more rare options like custom size pistons for Alusil block, Nicasil coating or steel liners etc. Answer to question who has 6L piston kit is no one really as there are no 105.5mm (GTS crank) or 110mm ('78-91 crank) pistons available. Since only way to make it work would be to use wet steel liners and there aren't any kits available like that.

Erkka summed it up perfectly....
basically the easiest way to increase displacement is with a stroker crank & overbore pistons...all depending on what you plan to do with the car......there are many 6.4-6.5L strokers out there with the 95.25mm crank and 104-104.5 pistons that make A LOT of power.....some close to 600whp

WHO HAS THE BEST VALUE IN THIS PACKAGE>>> THIS IS WHAT I WANT TO SEE/// Cost needs to be terrestrial.

Come on! You gotta do it! You said you would!
I really want to see that....that has to be sick.
Then come to track day and have some fun with us!
(Sorry about last night man...had a few too many here...it's a clear and present danger tonight too. lol)
