COME do a 396 stroker kit for the Holden engine.

The biggest hassle going bigger than 355 (3.48″ stroke) is that you hit water when grind clearance for the longer throw of the stroker cranks.

Dumb ass lS owner question here, but can you go 383 with the Holden block? Or is 355 pretty much it before you go aftermarket billet block?

 

396 with overbore gets you 402ci in standard block.

 

365-370ci is the sweet spot.

I see 383ci floating around a bit, they are Holden block or LS?

383 is a common Chev size.

Originally they used a 3.75″ crank from the larger 400cu engines ground to suit the 350 block, later the after market took over with cranks specifically for this upgrade.

Can’t say i’ve ever come across a 402ci Holden with factory block,can be done but would require a 60 thou over bore.Not greatest starting point for a strong bottom end i would think.

Agree 370ci would be the best balance of torque vs revs.Shame C.O.M.E. or Scat don’t make them.

454 ci is a pretty good capacity for power & torque

Exactly.  With the Holden block you really don’t want to go over .020″ – .030″ over bore as they have fairly thin bores to begin with.

You could use a Scat or COME 3.48 large Chev journal crank and have the big ends offset ground to Chev small journal size to gain a few extra cubes.

Slow355 – Best time was 12.67@108mph, 1.80 60ft. That was at Calder. I could match the mph at Heathcote but never hook up. Spin city.

So I spoke to the old man and it’s all systems go – He’s stoked to take the car off my hands.

I’ll probably drive it around a little longer to get more experience with the tuning side of things and let a few other bits fall into place. Then it’s into finalising the suspension and diff on the VN before I start on the driveline.

So in the end I dropped this to my old man’s place on his birthday at the start of November. He then took it on a few organised cruises, now it’s been parked up waiting for me to pull the parts off it I need.

I’ve almost finished a cradle to transport the engine from his place to mine. Then basically that’s the end of the book for me on this ride.

Looks like he will run it with a stock engine and baby cam, with the built 4k stalled auto and 4.11’s behind it.

Not a bad little safe and reliable fun combo

Crankshaft Rebuilders/Auscrank are pretty much the only company (in Australia) that can make you a Holden crank to spec. Sadly my builder and I have had much luck with them, but they are supposed to be currently grinding up an crank for me.

 

PS I accidentally reported the post.

Yep.

VN is now the ‘official’ project.
