    I think you left some hp on the table with the 9.7:1. With that much cam, even with the iron heads you could get away with 10.5:1 or more, on 93 octane. I run a similar 106 lsa solid flat tappet 250/260@.050 camshaft and 5000 rpm converter on the street, but aluminum heads, I run 93 octane with 10.95:1, and I probably left some power on the table as well, I bet I could get away with 11.5:1 or more, but next time. As long as it cranks less than 200 psi, it'll likely work with 93 octane. Did Dynamic Racing build that powerglide and converter? If not, they could make you quicker.

    Sorry, I thought you were running a 400, I was wrong. I use to run a 350 in my 73 Corvette with 186 Z-28 heads with flat tops, torquer intake with a holley 800 cfm. It was a fast street car over 40 years ago... I have a fast race car, 66 Chevelle 468, tube chassis car, weighs 2,370 lbs. with driver. 5.62 et. 1/8 at 123 mph. 8.82 et. 1/4 at 152.52 mph. 800 hp. engine. SV1 carb made by pro systems, billet carb 1150 or 1180 cfm. Running without power valves is not good. Causes hesitation in the carb. Jet size has to be 10 sizes bigger after removing power valve, thats what they say. If the engine doesn't have alot of vacuum at idle meed to put a 2.5 power valve in it. What ever the vacuum gage says at idle you are suppose to put a power valve 1" less than the reading...

  • @v8packard
    @v8packard Год назад +1

    Cool car. I heard you say your total timing is 34 degrees. What is your initial? With that cam, compression, and heads, I would expect 18 to 20 degrees of initial.
    If you decked the block or changed pistons to something that can get you .035 or so piston to head, it might make best power with about 32-33 degrees total. You might even lock it out.
    With an increase in compression you could run a 108 degree lobe separation angle. As well as a bit less exhaust cam timing. It will 60 foot harder.

    • @nylegreen261
      @nylegreen261  Год назад +1

      Timing is locked at 34 degrees. If a changed the piston to head clearance to .035 what would have the greater effect on power quench or compression. What effect would going to a 108 l.s have. I think maybe reducing overlap. Cleaning up the cylinders at lower rpm. Same effect as reducing duration.

    • @v8packard
      @v8packard Год назад +1

      Reducing piston to head will increase compression, improve quench, and increase power. A typical 906 head measures 63 cc chamber volume if the valve job isn't sunk. If you could get to .035 piston to head clearance your compression ratio would be right at 10.4:1, all else being equal. If you milled the heads about .010-.011 you will have approximately 61 cc chambers giving you 10.6:1. The increase in compression will improve torque at all speeds and will support the large cams a little better. Increasing the cylinder pressure helps the exhaust get through the head a little bit too, which the 906 casting needs.
      The 108 degree lobe separation angle is a better complement to the 906 heads with a compression ratio in the 10.5:1 range and stock valve sizes. All other things being equal, the 108 LSA will close the intake valve later than the 106, which will help it breathe in the rpm range you are working with. It will slightly reduce cylinder pressure compared to the 106, too, which might help you on street driving. Though the net change from the higher compression ratio will still be an increase in cylinder pressure and torque over your current combo.

    • @nylegreen261
      @nylegreen261  Год назад

      Nice thank you. I was thinking I would keep the same intake centerline @102 and move the exhaust side to get the 108 l.s. I want to try higher compression. Im worried I won't be able to run on pump gas.

    • @v8packard
      @v8packard Год назад

      @@nylegreen261 If you install the cam with a 108 lsa on a 102 degree intake centerline, it will be 6 degrees advanced. This will close the intake valve earlier, increasing cylinder pressure. That could increase fuel octane requirements.
      I am confident that you can bump the compression as I described, and with a 108 degree lsa cam installed on a 104-105 degree intake centerline you will still be able to use typical pump fuel.

    Man if you blend the bowls all the way and tear drop the valve guid bosses into the runner and do a 4 or 5 angle valve job and back cut all the valves you will pickup between 50 and 80 HP...just lapping those valves in is killing the flow especially on the intake side...if you fix those heads you will run 10s very easy....

      You'll need springs with a seat height of 1.8" , I run a solid roller with 1.7 ratio rockers and the lift is .603 on the intake and the spring seat height is 1.8 but you'll need .1" longer valves. The heads I'm running are the old school bowtie's from the 80s , In your case with flat tappet valves and running on the street, you best stay put. @@nylegreen261
