    Auto or manual? Honestly those numbers don’t seem too far off to me.(torque seems a bit low.). Did Lidio also tune it?

    Years ago my 410w put down 43x or something along those lines on Lidios dyno. I was never impressed with the number but the car outran plenty of cars boasting bigger numbers.

    Picture of the plugs? How fast is the coolant reaching op temp?

    That seems like a 500 horse combo to me not a 600 horse combo. 550 horsepower would probably need 12 to 1 compression and a bit more camshaft which means a bit more RPM..

    600+ hp would probably need 15 to 1 compression and 8500 RPM. my 396 small block head 230cc heads more camshaft and 11 and a half to 1 compression and that made about 575hp. That was a hundred twenty eight mile an hour on motor at 3450 pounds with a Powerglide.

    If it was through a loose convertor then that would explain it all.

    Haven't had a chance to look at the plugs.



    The car is an auto and the coverter was locked for the dyno pulls

    I honestly dont remeber. I messed it up though when I ordered it becasue I thought I knew better lol. It wasnt huge. Around .650/.680 lift and I know advertised it was over 300 a bit. It was a solid roller. I had them put it on a 108 lobe, but it should have been on a 110 or 112. Would have made more power dammit. I had lot of little stuff done to the rotating assembly, and the cylinder heads were VERY good. I spent over a month coming up with ideas and what to do with the ports and chamber. Intake was a crappy team G single plane the was untouched except a port match.
