I need help picking out a camshaft for a twin setup, I did use the X1 cam for the first and only run it made. it self destructed and now is in the process of getting bored, take the good with the bad I guess. I also would like to know what is a good stopping point in displacement with the stock 346. let me clarify that a little, how big can I go with out resleaving the block or would that be a good Idea when doing a stroker motor.
thanks

If it's a 99 or later block you can go up to 3.910, but you should look at what pistons you plan to run before you machine the block.

I am running some 9:1 Diamond pistons for a 3.905 bore.

I would think that with a turbo set-up you would want the strongest block possible. I would not trust a maxed-bore stock block. I would want a sleeved block. You can get 4.125 or 4.155 cylinders easy. Rumor has it a 4.200 cylinder is possible. There are a number of different stroke crankshafts you can try. Max displacement at this time I think is 471" using a 4.2 bore and a 4.25 crank. This set up will not rev very high though if that matters to you.
