whats the biggest stroke a 11.2 block will take without issues? recently lost a motor and just decided to go big. (in a way) looking to build a 738 or so, or am i looking at the 11.7?
also will a normal belt drive bolt up?

Belt drive is the same
5.125 or 5.25 stroke fit ok
If you want to go much bigger, you'll need a 12 inch block
If you want to go big, there has been a few 800+ motors for sale

My 706 CID engine is done with a 5.300" stroke crankshaft with aluminum rods in an 11.200" deck height block. That required a ton of bottom end clearance work. The block was initially set up in a Bridgeport, then after that a bunch more hand work. You also had to switch to the wider IHRA stroker motor oil pan rail bolt pattern. Yes, the standard Danny Bee belt drive works. So for any strokes longer than 5.300" I strongly recommend going to the 11.700" block, or then the 12.000" block.

is the 11.7 block set up or clearance done already for the larger strokes? bigger then 5.300. or is notching and clearance still needed just not as much?

I don't know for sure, and I own a new 11.700' deck block. I just haven't picked it up yet. Call C&C Motorsports and ask Chris Carter.

Mark, the traditional 385 Series Ford block deck heights have been; production 10.300", then aftermarket Mountain motor heights of 11.200", 11.700", and 12.000". Along the way the oil pan bolt pattern got widened for the strokers and the bore spacing increased to 5.000".

49 % of me thought he was joking, 51% of me thought maybe this is a serious question about deck heights. So the 51% won out. Sorry.

You're still going to have to Clearance the 11.7" Clearance will also vary depending on what rods you're using.
