406 |

Hi all, I considering building a 406 out of a standrad bore 390 block i have. The block is an X block which from everything i have read is either a high nickle block or is cast heavier. I have two such blocks. Can these safely be bored out to 4.13 or should i just build another standard bore 390. I also am figuring on running around 14.1 compression. This motor will be strictly race. I figured the money it would cost to build a 428 i could build a bullet proof 406. I basically looking for info on pistons, if i can bore the bock this far, and if a cast crank is strong enough to take 14.1 at 6,500 rpms with eagle rods. The motor will be going into a 69 mach one. |
