    Big Block seems to slow

    13.89 @ 100mph now. New plug wires, plugs and distributor cap, with a little more tuning woke it up tremendously. I’m happy with it now but it still a weird car because it doesn’t run on the ignition box since previous owner had points setup in it. But going to keep it like it is and build a...

    Big Block seems to slow

    Got it to where it comes off the line nice after a lot of tuning last night and today but now I have popping in the exhaust at around 3k Rpm. Chasing that issue now but slowly getting better. This car was held together with boogers and bubble gum I swear.

    Big Block seems to slow

    That’s what I’m wanting is a double pumper. Got it to where it’s way better after I adjusted the flap on the secondaries and made the whole difference. It doesn’t completely die when I floor it from a stop now just slow. Gears will fix that issue and probably a performance ignition box.

    Big Block seems to slow

    It’s getting way to much fuel in it. Put the accelerator pump on lowest point and helped it out but not a whole lot. Going to pull the jets and see what they are and go smaller if needed to see if that helps.

    Big Block seems to slow

    So the issue is stock cam(if not stock not much bigger) big intake and big carb. Probably going to go down to a 600cfm from the 750 that’s on it and see if that helps more. But at this point I’m Just glad I got it to where it actually runs decent.

    Big Block seems to slow

    First track results was a 14.4 @ 96 the thing is a pig off the line bogs hard unless I slow roll into the throttle. But once off the line it picks up great. The 2.94 gears ain’t helping at all so guess that and going to a dual plane RPM intake vs the huge single plane I have on it.

    Big Block seems to slow

    Rebuilt the carb (found sticking rear blades not opening), retimed again set to 12* initial and 36* total (probably off from ideal due to where the timing marks are hidden under the water pump but seems to be the best I can get for now), new kick down cable, and readjusted shift linkage pretty...

    Big Block seems to slow

    When you come from a mid 9 second daily driven hellcat everything seems slow just not this slow.

    Big Block seems to slow

    Well guy said it had a small cam in it but is also the same guy who had a copper tube rigged for a kick down so I’m sure it’s stock. Going to run through the rear gears and compression test today.

    If I didn’t tune it first I wouldn’t have posted in here

    Big Block seems to slow

    I picked up a 73 Duster that was supposed to be a 440 big block but ended up being a 65 361bb. I was a little pissed at first but got over it because it still runs and drives fine has the 727 and 8 3/4 rear decent interior and body. But my issues have started now. I installed a kick down cable...
