Decking a block
How far can I deck the early Cummins block? I see they make .020 thicker gasket so I imagine at least that far. My thought was decking the block to bump up compression by reducing piston to head clearance. But if I over decked the block then set my clearance by milling the piston tops then I could also reduce bowl volume and further increase compression. Even if I could get away with decking it .030 or .040 I'd be in the money I think
Cold Crank PSI
Brand new build, I just cranked it over for the first time. Running about 18PSI on oil for cold crank. How does that sound?

He351 on a ve
Does anyone have first or second hand experience putting an he351 on a ve truck? Curious on your thoughts
VE Swapped 24v Timing/Tuning
Ever since I finished my ve pump 24v I've been running into issues with what I believe to be higher EGT than normal. Mostly during WOT pulls maxing out my gauge at 1600F, but also cruising at high speed on the highway (~80mph). I have everything done to my pump that I know of besides getting a bigger pump and timing spacer (ratman fuel screw, fuel pin, full cut DV, clipped 3800 spring). Im running dynomite diesel 125hp injectors popped at VE pop pressure. They picked that injector because that matches the flow of their stage 1 ve 12v injector if i remember correctly. Turbo is an he351 with a 67/76 turbine wheel/bigger housing and stock compressor wheel. I installed the larger turbine wheel and housing to battle high EGT but it had almost zero affect on it. The truck doesn't really even smoke that much unless I floor it below 1500rpm (nv4500). WOT pulls leave a gray haze behind me but definitely doesn't leave a black cloud. Normal driving it really doesn't smoke at all. I have the fuel pin all turned out as much as possible for lowest base fueling and same with the starwheel(high preload), requiring boost to build before it starts to add fuel. When the engine was out of the truck i set my timing to 16 degrees with an indicator and even though I have removed the pump multiple times since then believe the timing to still be around there. Point of this post is, after much research I found a user (ScreaminDieselPulling) on one of the forums claiming 26 degrees static timing on the same sort of setup completely changed the EGT during pulls from 1500F by 5th gear to being able to complete a full 1/4 mile at 1100-1200F. As well as dropping cruise EGT from 650-700F to 400-500F. So, I am going to slowly attempt his recipe and report back on whether or not this is viable. I probably won't go all the way to 26deg as it feels excessive for my daily driver, but 20-22 may be in the books for me. I don't have an upgraded HG or Bolts/Studs so if I am about to be in a world of hurt please let me know. Or, if anybody has some applicable experience let me know because there is very little info on timing VE swapped 24v trucks that I can find. Am also curious about whether or not the timing spacer would be a better idea to give a better drivability.
24valve ve swap
Alright this is what I've got so far I've turned up the fuel screw I've played with the timing right now it's set to one past c I'm running stock injectors what do y'all think my issue is has throttle response but won't idle after giving it throttle and if I don't touch the throttle it will idle but almost dies then picks back up a little bit
