    Nice tip on balancer, I have a couple degreed stockers that would work well on.

    Got a little more done today. I painted the ugly military green tubing on the fuel rail satin black and installed the injectors, fuel pressure regulator, and injector harness. Also installed the crank pulley, Billet Specialties water neck and PCV valve, and the GM oil cap. The MSD Blaster coil sits where the ECM usually sits on these engines. Since I got my VHX gauge set I'll install the sensors from that kit.

    I'll probably install the lower intake permanently this weekend.

    The past few days I got the lower Ramjet intake manifold installed permanently and finished up everything on the topside of it. I added the home-made throttle linkage bellcrank and cable support, distributor, and stainless heater fittings. I was kind of surprised that four intake manifold bolts are not used on this intake, since they're normally where the upper intake attaches.

    After lubing the rockers with oil I installed the valve covers, wire looms, and GMPP plug wires. Also cleaned up and installed the throttle body, modified and installed the IAC housing and valve, TPS, IAT sensor, and MAP sensor. Still have to get some fittings and hose/tubing for the PCV system but that's about it. I won't permanently install the upper manifold until the engine is in the chassis...or maybe until the body is on. So the engine is essentially done.

    Next is dialing in the bellhousing for the T56, painting the bellhousing and the transmission, and getting the flywheel and clutch installed. I'll do some of that assembly with the engine in the chassis. I'll install the water pump and accessories when the engine is in the chassis too.

    Looks awesome! Just need to re-do #7 plug wire, and make it run.

    Thanks RD. The plug wires are from a set that is custom fit for this engine by GM Performance Parts. #7 isn't as bad as it looks, but it may be a little long. I don't know if I can shorten them or not. I think one other one is a little long too. Once it's in the chassis and the body is on I'll check it out.

    I just added up the rebuild costs and the total was $2173...on a BRAND NEW engine.

    That was $1854 in parts and $319 in new tools I may never use again. Some of them are pretty worthless and some are going back to Summit. The TDC piston stop doesn't work and even got bent in my engine (read about this happening to others). The Manley pushrod length checker doesn't give the same results as the witness marks so it's going back. I ended up not even using the checking springs, but they were cheap. I also have a slew of parts to return that I tried or decided to use something else, as well as some stock 502 parts to sell that someone may want. Already had a friend ask about the cam.

    So here's what I ended up doing...

    Torque plate hone block
    New cam bearings and freeze plugs
    New Total Seal standard tension piston rings
    New rear main seal and rear cap o-ring
    New Custom hydraulic roller cam (Mike Jones)
    New COMP dual roller adjustable timing set
    COMP valve spring locators and shims (150# on seat)
    New Cometic MLS head gaskets
    New Trickflow pushrods
    New Scorpion Endurance Series aluminum roller rockers
    COMP Polylocks (replaced the Scorpion set)
    I pair GM valve locks (replaced damaged/wrong one)
    New GM intake gaskets
    Bunch of ARP stainless 12 point bolts

    I re-used everything else as far as gaskets, seals, bearings, pistons, etc. I ended up changing more than I planned, which is what I was afraid of.

    But it's done.

    Is the R-Jet manifold painted or powder coated? Looks fantastic.

    Marty, the manifolds and valve covers are PPG urethane in a dark gray metallic paint. It's the same color as some of my chassis parts.
