    i seem to be having a bit of trouble with acceleration. to start timing is good new plugs, accel super stock wires, adjusted valve springs, newer 650 cfm edelbrock carb. when i step on the gas it doesnt seem like it wants to go does not rev high. it just seems like your halfway throttled. its an older intake but im going to swap out with another. i had this engine in a 85 camaro and it hauled serious ass(blew tranny gave away body). then i bought my monte put it in and its slower than dirt once you get going itll go but off the line it sucks. barely do a damn burnout frown image the only thing differant between now and when it was in the camaro is the intake, mech. fuel pump and distributer (non vac. adv. to vac. adv.). gonna change intake, fuel pump i dont see being much of an issue it either works or doesnt. the distributer i want to change but i want to know if that can be an issue or not.

    What kind of gear ratio does your Monte have in the rear end? It's the '78 you have listed on your garage page, right? I had a '78 Bonneville with a 350 in it, and it was slow as Hell. It also had something like a 2.2 gear ratio in the rear end. A lot of GM cars in the late 70s had low ratios in the rear end, causing even high torque motors to lose their kick. It was GM's answer to the gas crisis: The slower the engine spins, the less gas a V8 will use. smile image Except that didn't work well. My old bonneville still got sub 10 mpg in the winter cold and it had no nutts off the line. I wonder if that's what you're running into with your monte? I also wonder what your '72 Nova has for a rear end gear ratio.

    Hey I hope you have already solved your problem. I was wondering if you had checked to make sure you do not have a brake stuck. I know it sounds weird but had that problem on a T Bucket a few years back. I know it sounds like a carb problem, but weird things happen.
    Take care,

    Yeah, and to add to that, my mom broke the parking brake in her car when she tried using it after not putting the parking brake on for 15 years. If you have used the parking brake recently, the metal wire might have rusted enough that it broke when you put the parking brake on.

    I'm trying to remember, though, if when this happens the parking brake clamps down so the brake is always on... I think it does. Putting the parking brake on snaps the metal wire, and then it won't release.

    Of course I'm just pulling at strings. You might not have even touched the parking brake at all. smile image

    man i'm glad i am not the only one with that problem i have 78' monte also. I have a 350 5.7L i recently changed the oil, sparkplugs, added a adapter to the 600 cfm elder carb(replaced the gaskets) @ first when got the car it didnt have a catyl. converter so i had to add one to pass emision for inspection. and that fix the exhuast leak that it had... but i still dont have that intial pick up it should have... it is very slow off the line, i cant even burn rubber if i set fire to the tires lol.... i also ran seafoam through the carb too to see if that will clean it out a lil bit. i am lost now.. mad image
