Lineslinger Mark you are already buying a crank. Decide the stroke for your crank, you may want to go larger than 3.98, 4.25 or 4.1/8 and get some free extra cubes. A little triming in the block is needed for clearance. BBC rod has a wider surface to support the load on crank. If you are going with BBC rods, talk to Howard cams. I got a set for my motor, they are wieghted and within 1/2 oz of each other. He said that they are good for 1k HP. They there $100.00 per rod. More money than Scat or eagle rods( I have them in my first motor without any problems so far) and they are 3-400.00$ cheaper than Manley,Jessel, or Crower. They are also US made. On the crank you want it to be cut 2.1998 so the machinist can get the correct clearance when done. A custom set of pistons will be needed. KCR or Gessford keep them in stock. Get all ARP bolts and studs for the bottom end and do the
oil modifling in the block. Buy a accump tank, 3quart and use it as a engine pre oiler. Keep the rpm under 6500 and you will have a hell of a strong engine. Go for the Tork, hp is extra
