I ran a low buck 406 for a while, with 5.7 rods, but broke a rod bolt because i had stock bolts, never again i'd definately put some good rod bolts in it. The TRW pistons are heavy,heavy,heavy. 7200 if'ie maybe 6600 and be sure to sonic test the block before boring it.

Mark those pistons prob wont work with a 3.75 stroke you would have to use 5.56 rods and hope you have enouph piston to crank clearance. Just saying might not b a good way to go and i dont like short rod like that just my opinion!

hey pat... what is up... hows your bug coming along?? i traded for this stuff it was a 377 set up... you are right according to sealed power i HAVE TO run those 5.565 rods or stay at a 377 with 5.7 rod and 350 crank... was looking for more torque as you know... lol... do you think it would turn 7000 enough to run this season before i go big block??? thanks caveman.... :D :D :D
