406 sbc vs 383.

The only problem i have with the 400 is the block. They came in heavy vehicles and got worked hard from day one. I was to build one for my 4x4. i went thru 6, yes 6, 400 blocks before i gave up and went to a 383. the main decks cracked all to hell when the torqueplate was put on. For your sanity, build a 383 or build the 406 with an aftermarket ...I also built a 6 inch rod 406 sbc and the car slowed down about 3 tenths.I discussed this with Bo of BLP and he stated had built a 6 inch rod sbc and was unable to get it to run as fast as the 5.7 tha it replaced.
