any data on the 7 bolt 2.4? Same as 2.4 GCS?

Bores and stroke are the same.

How about those mythological 2.7's? :D

topic bitches before I start deleting shit :) if you really wanted one, you would need to have someone make a 88mm bore with a 112mm stroke, and probably have to weld another deck on.

Sorry Mike, back on topic. Someone correct me if I'm wrong on this:

If the deck height on the 2.4 block is 4mm higher than a 2.0 and you were to run 2.3 (stroker 2.0) pistons in an othewise stock 2.4 shortblock you would end up 4mm below the deck. That would mean that you could in theory stroke the crank 8mm (4 up, 4 down) and end up with a 2.55L motor with off the shelf parts (except the crank). I don't think it would be worth the effort but its just food for thought.

I believe it's 6mm, not 4mm.

I wasn't 100% on that, thanks for the correction Brent. OK so now we can go 6mm extra deck height = 12mm extra stroke with 87mm bore (.080 over 2.3 piston = custom?) will give you a 2.663L with a 2.4 block. That would be pretty nice! I'm guessing you would start to have some clearance issues in the bottom end with the large ends of the rods hitting the block?

I had to clearance my stroker crank in my 2.0 block, and I've seen how much you need to take out of a 2.4 block when usiing pauter rods, there is not enough room for 12mm more stroke.

The biggest bore u can go on a g4cs is 88mm(.060 over). That gives u 2433 CC's or 148 C.I. with 100mm crank. From almost of the shelf parts the biggest displacement u can get is 2482 CC's or 151 C.I. That’s 102mm crank from crower custom length rods and of course pistons.(that big money for 50cc or 3ci). Now there is another way to increase the displacement is to insert custom sleeves and increase the bore even more along with custom rods and crank. I don’t know how big u can go on the crank since 2.4 with pauter long rods (156mm) have clearance problems, they hit the bottom of the cylinders skirts and need to be notched a little for the rods. The best way is to use the g4cs block (if u have money use long rod) and 87-88mm bore depending on the use of the motor. Boost will be the best replacement for displacement at this point.
