  1. Drivetrain & Performance
    Hello everyone, first post here. I'm not new to working on cars but I've never gone in depth before and I'm feeling a bit defeated and like I'm in over my head. So I have a 5.7 350 SBC in my 1976 Nova 4 door. It ran for a while and now has died, I wasn't getting spark but I was getting 12v to...

    I've got a 1972 307 that I upgraded with a mild cam, 4 barrel carb, Edelbrock intake, 305 heads. My distributor is still stock but I swapped the points for a pertronix ignitor unit. I'm getting some jumping in my timing (+/-2 deg) and overall am not totally happy with the timing. I've set...

    Hey guys So my 62 coup with a 250 wasn’t running good so I decided to check the timing but the car won’t run or start with the vacuum advance disconnected. I did try advancing the time if to make up for no VA but it didn’t do anything. Any ideas?

    I have a 1972 Pontiac Ventura with a 307 engine. I swapped the stock 2 bbl carb and intake with an Edelbrock 1406 4bbl and airgap manifold (I saved the stock parts, don't worry). The cars manual calls for timing to be set at 8 degrees btdc but it seems to run better closer to 12 degrees or...

    Hi! I recently installed an all new MSD 6al ignition system on my car. I also put an msd ready to run distributor on it aswell, Which has the mechanical and the vacuum advance on it. When i Put the new distributor it I reset the timing to 0. then not realizing what the mechanical advance and...

    I'm having issues getting my 383 started for the first time. The timing is off which I know how to adjust. The problem I'm having is with the starter/power. Sometimes when I crank the engine it barely turns as though the battery's almost dead, then when I try again it cranks normally, it's very...

    Hey all I'm looking for some timing advice... I have a chevy 427 big block and I'm looking to time it properly so I can go threw the carb and tune accordingly...I've read and spoke to different people and everyone has different advice/thoughts....all agree that high should be about 36-38 but low...

    73 nova with 350 engine and Holley 650. The engine started knocking, I took the heads off and two of the valves were bent. I got everything put back together and the first time I tried to start the engine it backfired through the carb. Whoops. After getting my plug wires on correctly and...

    I know there's a ton of info on here about this but I need some clarification. I put paper towels in each spark plug hole and turned the engine. As each cylinder fires the paper towel pops out. There's a line drawn (in sharpie) on my harmonic balance that I'm assuming should be at 12 o'clock...

    I have a question about timing that honestly I'm kinda embarrassed to say I still am not sure of the answer. So the question is that before i put the distributor in how do you decide where to set the timing mark on the balancer? What factors dictate whether its set on 0 or advanced and if...

    I just purchase my 67 Nova with a 406 sbc. Some basics on the car are 750 QFT Carb, MSD Ignition system, Edelbrock Vortex Air Gap Manifold, Edelbrock E-tec 170 Aluminum heads, hooker competition headers, 5 spd Tremec TKO 600, 1973 4-Bolt main block, with forged pistons and a competition cam...

    I just changed out the points on my 63 convertible nova i6 194. i read a ton of stuff on here that said you had to change out resistor wire. this would be the braided wire that goes from the terminal block on the fire wall down to the starter, right? (that's where mine went) well the...

    Hi Everybody, I have read everything in here about adjusting the vavles on my car. I have a 194 inline 6 and I am having one heck of a time adjusting the valves and was wondering if my timing, or lean or rich mixture or idle screw is messing me up. Before I started to adjust my valves my car...

    I just noticed that the centrifugal advance on my distributor goes from about 15 degrees up to 36 but then seemed to drop off about 1 to 2 degrees. Does anyone know if it is supposed to do that?

    I have an HEI (Summit) distributor that needs help. The distributor is connected to a Summit multi-spark/rev limiter box. It seems to be able to muster about 18 degrees of mechanical advance and way too much vacuum advance. It seems to be "all in" by about 3400 rpm. I'd like to see it all in...

    I have a 383 roller motor that just quit on me and the cause was a surprise. The motor can't have 10k miles on it. I really didn't expect the distributor gear to be shot this soon. I have a GM HEI distributor with a bronze gear. It mates to a Comp hydraulic roller cam through an Edelbrock...
