    Holy Crap Bill, are you just trying to reinforce the title you gave this thread? Another bummer but like others, better to find out now than in the middle of your Hero pass...

            Why not run a SCAT forged 4.5" crank?

              Because the crank with three cracks in it, one on #2 and two on #3 was a Scat forged 4.5. I had no troubles what so ever with my first Scat cast steel 4.5" when the power level was a bit lower and we upgraded to the forged version because I was going to spray it.

              Never did spray the forged unit, but we did do some N2O dyno testing on the cast steel unit with no issues. Some believe that the Fluidamper I have been running for years might have been the issue but again the cast crack didn't have any issues. In any event I have to change dampeners for the new crank so it'll be an Innovators West unit now.

              I expect to pick up 2-3 HP because the crank throws are more aerodynamic.

                I am definitely in that world, the rods are 6.8 BBC's except for the additional .020 on the with to get the right side clearance for the BBF width, BBC diameter crank pins.

                  I think all of us big block Ford guys are in the BBC rod world; I must have six or seven sets of those things in various motors lying around the shop. Doesn't bother me a bit; I just think of all the Chevy guys running a 9 inch. The objective is to use the best parts available, no matter the origin.

                  Bill, I would be thinking ATI for the damper. I've heard from several crank manufacturers that the Fluidamprs are tough on cranks, although the normal failure mechanism is that the crankshaft snout breaks off. Get yourself a heavy ATI damper for that stroker engine; your crank will thank you...

                    6.7" BBC size rods here! Cast RPM 4.5" crank though...

                    The 460 guys talk highly of of the Innovators West dampers. Never used one or seen one up close though.

                      I looked at things as this is the Center to Center its fits what it fits, the Buick I built had a .040 Mopar 440 piston in it ( OK 8 of them) I think we used a Hemi rod in the 429 Strokers we did for a while. Parts dont know where they are LOL

                        Yeah, crooked road indeed. Most of the valve train parts are BBC derived although the term BBC covers a lot of ground these days given I'm not aware of what original BBC had 5.750" long valves with 2.40 heads. 4.56" bore size seems to be a popular BBC overbore though.

                        ATI doesn't have a part number that keeps the Ford four bolt pulley pattern and stock 429/460 pulley flange location on the short snout Boss crank. Innovators West does. Thank God for the FAST racers.

                                The Buick I did we used a .040 Mopar 440 piston in it, flat top with 2 valve reliefs it cam was in at 102* and made 320 PSI with 3 cranks over. Major Grunt off the line
