Heath its your big ends that you offset grind to stroke an engine not the mains. So although you could offset grind your big ends to increase the stroke, why would you need to use a 179/186 block?

Machine main bearing journals down for 186 bearing size and offset grind stroke it.

I never said you offset grind the main bearing journals (well I'd hope not anyway!). You just have to grind the main journals down to 186 bearing size to fit it into the block.

If you want a 202 or just over it's probably cheaper and less mucking around to just use a 202 block!! You can put a 186 type head on a 202 with no mods if your dead-set keen on cubes with the 186 head!!

Done deal!

I think what heath is trying to say is if you fit a 202 crank in the 186 block the mains are smaller, so there is less bearing two journal friction . :huh:

The original question was how to build a 202 with torque, there was no mention of using a 179/186 block. I was just wondering why Heath said to use a 202 crank in the 186 block.
I thought that maybe there was a trick I wasn't aware of ????
As Kieth said, its easier to use a 202 block, which has the added advantage of being up to 15 years newer than a 186 block.
