I recently purchased a new Hamilton 6.7 std bore block and having a shop do the install and any machine work needed. Was gonna run a sleeved down block to hold higher hp and the shop kinda strayed away from going this route wanting to keep the bigger displacement for drive ability on the street since this is for a street truck not strip dedicated truck. The goal was 1,500hp max and since I’m running QSB pistons to keep it happy on the street they decided to not sleeve it down cause it was gonna cause it to have to take .80 off the pistons to run the 6.7 crank if sleeved down to a .40 5.9 bore and since not running a custom forged pistons that could spell trouble losing that much material so I told to ok we can stick to std bore 6.7 cause they assured me the Hamilton block is stronger and they feel comfortable it holding 1,500hp and below not sleeved. Now they called me wanting to drop the stroke to 6.4 which I’m good with so I tell them go ahead and they can send the standard length rods back to wagler and get the .80 longer ones to be able to run the 5.9 crank. Well I didn’t hear anything for a day or so then come to find out instead of sending the rods back they milled .80 off the top deck off the new motor and said it’s too late now pretty much and that it will still hold the power goal as is cause the block is .80 thicker then OEM blocks. So my question is did this shop just screw my block up and set me up for failure or has anyone else run this set up besides Ashley Black and it actually hold decently? I hate to think these guys ruined this block cause they are actually a bigger name shop.
