You may need to machine new cam gears to match the different teeth on teh timing belt depending on which water pump/oil pump combo you go with. You might think about taking a 1.8L crank to scallies(sp?) and have them add another rod journal next to the stock location and then center them. This way your heads would be offset an inch or so. Some of the old school v8's did this(dont remember what its called exactly or who did it...but I remember seeing it) Scallies crank will cost you an easy 1500 dollars. Get your block of iron and chuck it up in the cnc mill after you write you program in AutoCad 2004. But that still doesn't take care of the coolant ports... You may have to get it casted, or.... switch to a sleeved design..in aluminum. which the sleeves would help create a nice coolant jacket around the cylinders. you could drill most of the oil passages.

I'd say start with drawings. You're going to need to have the crank made....and maybe a cast block. If I were you I would make a dummy block out of aluminum. machine it so you have the correct bore, the deck height you desire. Then bolt the heads on so they are slightly offset(the same offset as the width of the end of the rod that attaches to the crank), and start looking at the timing belt situation. You'll need an oil pump, water pump, tensioner, and idler pulley. I would try to stick to B series components, as to try to keep the same timing belt (teeth per inch) or whatever the hell they rate them by....AND WIDTH. You'll prolly need to put an idle in between and below the heads to make sure that the cam gears get at least 90 degrees of traction on the belt. Dont forget that you shifted one of your heads in order to offset the rods... you'll need to extend this cam gear so that it is inline with the cranks(custom cams???) Once you have your custom timing belt made and it tensions correctly...machine hte back end of the block so that the tranny will bolt up to it. Mock everything up on this aluminum dummy block...get all of your programs written so that you can have a perfect setup when your real block is started. Send your crank out to be made. machine your mains, set the crank in, and machine your block. figure out your bore size.... send it off to benson or GE and have it custom sleeved. Have your own set of rods made(custom length B series rods) and run whatever bore pistons you want. and remember..you can still use oem honda bearings.

thats about all teh imagination my mind can take tonight... peace out girl scout.
