Is it safe to deck the block 010 in the hole? Cause i rather just deck it at 0 and just get the proper ch piston rod combo to get it at or slightly below were it should be at. Will i have any clearance problems with the rotation because of the longer rods? I wanna get a sound and durable base and just get my horses out of the heads and intake without going to wild on the camshaft. Thanks

they do not make a shelf steel rod in 6.525 they make them in 6.535 jerry was running alum ? i would bet so yes you need to make up the short comming on the 9.800 .427 to the 427 tall deck that you need the 6.535 rod as for cutting the deck 010. i have cut over 050 off the deck it will not hurt the block but it did throw other things off then deck . even on a 10.200 every thing needs to be ajusted for the deck heigth . you will not get in any trouble using a long rod s you say you want to see horses out of just your heads not much cam or cr or cid and low rpm boy thats going to be a job .i would go for TQ and not HP and that can be done with more cid i be looking at a 454 .4000 crank 468 or a 4.250 that get to 496 and that will make alot of tq if the rigth year block i put a 4.500 crank in a 427 tall deck out to 525cid with not much work on oil pan rails and that made much TQ there is some tall deck intake but at the time i built the 525 i used spacers they did not make the air gap in a tall deck so you need to see what intake you want to run and see if they make it for a tall deck. when i built my first 572tall deck dart was the only one making one a that was a race intake not something you need on your build over 17 years ago there is more tall deck intake made like jerry said
