    I got the new O-rings tapped into the block deck today and the heads on. Camshaft installed and degreed. Hopefully by Sunday I have everything but the rockers and pushrods buttoned up.

    Man I can't wait to see what this thing does. I'll put as many miles on it as possible this summer and then see if I can rig up about 10-12 pounds of boost this winter.

    Nice man! Looks like a stout build up, I will say your the first I’ve seen with a ringed block.

    Is that ringed with a receiver groove in the head as well? Also curious to me is the oiling mod that is going towards the timing area.

    Looks awesome can’t wait to see it come together and fire off

    A little spray of oil on the roller cam/distributor gear. Saves the cam gear on a Buick 455. May do nothing on a Cadillac engine...………..but it makes me feel better.

    I did an easy modification on an Oldsmobile aluminum 215 running a reverse camshaft for the same reason; to spray oil on the reversed cam and distributor gears.

    That motor and monster intake makes that carb look like a tiny 2 barrel :).
    Can you fit those coated headers into that chassis, those look nice.

    Coated headers fit the car without the A/C box. I’m not giving up A/C.

    Thanks. The engine looks like it belongs in the car. It was a nightmare getting it to that point. The front end is not aligned well so I have not been past 50mph but it does start well, idle beautifully in and out of gear, and maintain speed without a hiccup. It has ridiculous low end torque. Once the front is aligned this weekend I’ll get it past half throttle for the first time. With 3.00 gears it should pull like a freight train. Fuel injection will be on my short list of wants for the winter. The fuel system back to and including the tank are ready and waiting for it.

    Yes they are.

    Here are all of the engine specs:

    1970 500 block 0.080" over with 0.020" deck clearance
    1970 500 crank with 0.0025"/0.0025" clearances
    1970 heads 250 with undrilled smog rails
    2.19"/1.90" valves, polished small chambers, intake ports raised 0.125", pushrod walls moved back substantially, bowls opened and polished, guides blended (all done by me)
    PAC 1.54" beehive valvesprings with 150# seat and 360# open (MTS rockers won't clear 1.55" dual springs)
    Comp Cams machined 10 degree locks
    PAC chromoly retainers
    Howard's red seals
    Comp Cams OD spring cups
    MTS 1.72 roller rockers. I drilled one 0.062" hole in each rocker to oil the tips and springs, prior to doing this it was dry as a bone under the valve covers which in no way appeals to me. Too much oil sucks and so does no oil. The T&D rockers I have have two 0.062" holes one for tips and one for springs. The T&D are better quality and higher priced.
    Comp Cams 3/8" x 0.080" wall x 9.200" long chromoly pushrods
    Hydraulic roller cam with 240@0.050" duration and 0.608" lift and 109 LSA set to 104 ICL
    True Roller chain
    Homemade bronze cam button with homemade distributor gear/cam button oil mist tube
    Stock oil pump with BBC purple spring, 65# max, 35# hot at 900 rpm idle with Valvoline conventional 10w-30 at rear of engine
    Blended and radiused main oil passage
    -6an braided hose from front of block to rear oil pressure port
    Durabond grooved cam bearings set at 10 and 4 o'clock
    ACL 0.010" rod and 0.010" main bearings
    ARP main studs
    ARP head studs
    Bushed H-beam 7/16" cap screw rods
    Probe 10:1 forged pistons pinfitted with dual spirolocks
    Balanced with Mallory metal
    Sealed Power moly rings set to 0.022" top and 0.024" bottom gaps
    O-ringed block with 0.040" copper head gaskets (pain in the ass)
    Custom rear sump zinc plated oil pan with custom pickup tube, trap doors, windage plate, etc. 7 quarts in the sump.
    Homemade stock valve covers modified by me to clear both adjustable roller rocker and stock air conditioner box
    Billet PCV valve and breather
    MTS single plane intake port 2" in to be just barely smaller than the head intake port
    Quickfuel 1050 annular discharge carb
    ROBBMC 1100hp mechanical fuel pump and regulator
    K&N 14"x3" filter and Xstream lid
    MSD distributor and Superconductor 8.5mm wires
    MSD Blaster 3 coil
    MSD 6AL with 6000 rpm chip
    Stock style solid impeller water pump
    180 degree thermostat
    1-3/4" Hedman homemade by me headers
    3" Pypes stainless full exhaust with Race Flo mufflers
    Homemade by me solid engine mounts

    And I THOUGHT that my engine build was involved … that was before reading the description of your build. DANG!!!

    I have NO doubt that you speak truth when you say, "It has ridiculous low end torque." Why is it that my tongue is going stiff just saying that?

    Looking forward to your report following that alignment!

    Best,

    Thanks D. I’ve seriously considered developing a bad cold with a sore throat to speed it up by a couple of days. Haha.

    My previous Buick 455 Skylark had about 500hp and a boat load of torque but nowhere near this much at low speed. What cracks me up just hitting this thing in the driveway is that it has a 2000 stall and 3.00 gears. My 455 car had a 4000 stall and 3.90 gears and still didn’t feel like this. That car ran 6.85 in the 1/8th and weighed at least 300 pounds more than this car. The track will tell the story.

    Big congrats on getting her on the road! That’s a whole boatload of work you’ve gotten done, you should definitely be proud of it!

    I also can’t wait to hear about your first full throttle pulls

    Runs real good. Idles rough at 12 degrees initial and 10.5 inches of vacuum. It only has 30 degrees total timing in at 2500rpm so I’ll install the 21 degree bushing in the distributor this weekend. I maxed out at 5000rpm and it would easily go to 6000rpm I believe. Burns the tires as it pulls the front end up and goes. No real harsh body twist like normal on a G-body car with the large rear sway bar. I’ll adjust the extension pressure down on the front shocks and see if it transfers weight even better. It is definitely faster than my Buick 455 car was but more docile when cruising.

    BTW what do you all think about my new hood ornament?

    Like it, you should also make a Coupe-G-Ville emblem with some creative cutting and soldering.
