    It’s been a while since we’ve posted anything so we have some catching up to do.
    900HP Cadillac ?
    Yes, we made over 900HP recently on gasoline with NO power adders.
    In the ‘70’s we made over 600HP and over 800Hp in the ‘80’s, so this was a milestone for us.
    I guess we shoot for 1,000 next!

    Now, that is right impressive!

    As you may know I am a 'forced induction' type of guy but numbers like you just posted can be reached naturally aspirated, if not easily. Hell, you just did it!!

    Tell us the combination used to reach that lofty goal. The compression ratio, camshaft specs and RPM had to be aiming mighty high!!

    Best,

    Holy crap....900hp NA is a pretty big deal even nowadays. So congratulations on the numbers!

    Did anyone else notice the intake is an old “bulldog”? Also looking at those headers...I bet they would be perfect for a boat!

    Pictures? I don't see any pictures on my view of the forum.

    Peak at 6550 is less than I had expected. My bet was that those numbers came north of 7,000! That sucker (pun intended) must be breathing deep and well!!

    I see it has a big Dominator. I wonder how far apart a 950 cfm 4150 would put it?

    Called Courtney. Ported boogieman heads, 1150 carb said might use bigger? Big solid roller cam about .800 lift 14:1 comp, flat tops with relief cuts. Stroker billet crank/3K, About 582 cid. Don’t recall stroke but rod journals are bb chev
    Said he hadn’t priced it but probably around $20,000 if you have him build one
    Darius you can’t see three pics I added to first post??

    NOW, I can see those pictures but somehow they did not show up when I first opened the thread. Strange.

    First of all, GREAT Pictures!! They help tell the story so much better, and they are appreciated.

    Those compression and lift numbers are about what I expected. I had not understood that the beast was stroked (pardon the expression:rolleyes:). Still, even with the added cubes those HP numbers are impressive especially given the RPM at which they are achieved. Courtney may have been spinning those large crank throws that hard since the 70's but I've long preferred that level of abuse limited to short stoke engines with 2.6 inch, 2.8 inch or 2.94 inches of throw. Staying in that range lowers my "pucker point."

    Thanks again for the info.

    Do I sense a return to the Engine Masters competition in the near future?

    They ran out of fun time. He was still testing with a Bulldog intake.. 1475 and 1250 carb will certainly make more power.

    This is not a girdled block.
    It has. Main studs cap straps and halo.
    STOCK cam journal dia.. .800 lift 280/290 @.05
    Mildly ported Boogieman heads..
    (Same porting as mine) hehehe

    582... 4.750 stroke... 4.42 bore...

    Btw the peak came at 6500 but some of the pulls have been over 7000 rpm
    With that giant arm. Pretty darn impressive

    I'm impressed that the old style Bulldog manifold supported those numbers! I knew they were the best production intakes available but thought they would run out before those numbers...More cfm will pick it up more...I'm running two 600's on the street and I'm nowhere near this compression, lift or stroke. My hats off to you!

    What is your combination? In the same way, do you like the overall drivability of your twin carb set up for the street? I'm curious because it is street driven and not a track only car.

    Best,

    I was sharing my thoughts with Julius and he mentioned some amazing numbers coming from your shop. So glad to hear the new developments. Keep us posted.
