Hey,
I have a 98 12v had an ARP head stud fail and blew my head gasket (~8 years)
I removed the head, had the head rebuilt / surfaced from a friend. 6 weeks later... I got it back from him. Put the new head on, 2 weeks later blew it again.
Decided to pull the engine, and have the block decked, and head o-ringed. While I'm at it have it freshened up.
I had a crack in cylinder 5 piston inside the bowl 215hp piston. Machinist is recommending Mahle 930036335, looks to be based off a NON-IC 1st gen Piston. Debated marine Pistons but didn't want to lose compression on a street truck; but I want a better bowl design. Good choice?
Disassembled everything and brought it down to a competent machinist / builder
My current setup is
215hp ppump (just sent out to get freshened up)
PDD budget 5x.012 injectors
AFC Live with max travel, debated deleting
4k GSK
cummins 60lb valve springs
he351 with 67mm exhaust upgrade ~45psi
new arp2000's again..kinda wishing i went 625 this time..probably overkill
upgrades:
Sent 215 ppump to Seth for rebuild, he recommended a complete overhaul and calibration.
Decided to do ARP rod bolts, was debating ARP mains.. but already 14mm stock. Is it worth spending the extra $250-275?
Balancing the rotating assembly
thinking an ATI damper
Bought a new aftermarket tappet cover (overkill fab) but may replace.. uses a cork gasket seems sketchy and it doesn't have a spot for blowby tube. Would it be bad to just run a 24v style at the front to a catch can only? I would go the dual breather cover but my valve covers are currently at powder coat, could always buy one and get it coated as well.
Bought billet oil squirters
deleting my vacuum pump and gonna run an electric vacuum pump
replacing freeze plugs with billet the common 3-4
fleece coolant bypass
Is there anything else you would recommend? power goals are kinda up in the air at the moment. he351 was rebuilt and that 67mm exhaust housing seems nice. It's a manual nv5600 with dual disc valair organic. I'd maybe go a 62 or 61-65-14 s300(even worth it?), but I want something with good driving manners, not laggy, quick spooling and fun. Feel like I would go compounds before a big single.
Why do guys run the adjustable timing gears, ease of changing the timing? does it make sense to run one if i'll probably just set and forget(thinking 16-18*). The billet timing covers look nice but what benefits do they have, being able to access the timing gear to make those adjustments?
Thanks for taking the time to read my rambles
