I hate the 400 blocks have seen them crack just bolting a toque plate on. The the only block when it comes in the shop I get paid 100% up front. Pretty frail block compared to a 350 block.

Using stock 400 rods in a performance 400 build in really not the hot set up !!!

Don't wast your time having some one grind an old 400 its some times a waste of money as when grinding a crank that much the oil holes do move closer to the radius.

I don't recommend using a externally balanced crank in a performance build.

If your building a budget build you can buy a Scat 9000 series crank for around 200.00 That will internally balance and they have one for a one piece seal block that will internally balance no problem , Scat 6.0 I-Beam rods with 7/16 bolts 300.00, Pistons Wiseco has a good deal on there Protrue series pistons and rings for about 425.00

If you can find a one piece seal block and use GM Hot cam 234/242 and buy there roller lifters as kit makes for a cheap roller cam and lifters. The Dart SHP 180 CC runner heads 64CC chambers.

I have done that build many times with very good results.
