Drivability issues solved with simple MSD Pro Billet distributor lock out. Our 100th episode!

[@stoneyswolf]

I've never locked a dizzy. I always thought it's more for racing not street driving. My thought would be bigger acceleration pump and experiment with pump cams and dizzy springs first. The higher idle wouldn't be a problem with the proper torque converter or a standard transmission. Clean car my first camero was a 77 back in 87 super clean silver with black interior. Had a 74 back in the day also.

The 2nd generation Camaro and Firebird are far my favorite cars between 1970-81 and including the Yenko Turbo Z

[@FamilysGarage]

Those are some of my favorites also, may build another someday 😎

Big cam and runners needs that advance to get it moving without popping, and the pump shot and power valves are critical. With the vacuum secondaries have you tried lighter springs, on singles i always had best luck with the second to 3rd lightest springs

My SBC 383 street car is locked out. Set to 36 degrees . Otherwise I was having trouble getting it to run correct. But I removed the vacuum canister.

[@PeggyParrow]

The gear needs to be shimmed to within .015 , they have to much slop and delays timing response,that will allow oil to still lube it, also if you pull the gear, orient it the same way it was,because the gear has 13 teeth on it , if you turn it around ,your dist. Orientasion will suffer .thats why GM dills a dot on the gear to line up rotor with it. Just trying to help !

I did not know that, thanks!

@cmsracing Thanks man!

Mechanical and vacuum locked out on my big block Nova. Mileage is 4 to 5 if I'm lucky. But very drivable.

Needs a 'part throttle' circuit additionally installed into the front and rear blocks that leads to the metering plate. Also , Jet for wot with one single size richer. Timing a single or couple degrees less than on the engine stand or dyno. Run great cylinder pressure with proper fuel enrichment on pump gas. Yay! This camaro is awesome.

Looks like you were running with the heavy advance springs in the dizzy, and I'm guessing whatever advance bushing stop msd installed. You want to first install the black 18° advance stop bushing, lighter weight advance springs, set your initial timing to 18°, you'll be at 36° all in. Big cam, hook the vac advance canister up to ported ( not timed) vacuum source. That'll give you even more advance at idle and allow you to set your idle lower. Car should be a rocket with these changes.

Looks like it helped out. Keep up the good content.

Wouldn’t run like crap if someone put the right springs on the advance mechanism…. For a lightweight car, stick shift, with probably a 3.55 or 3.73 rear gear from the sound of it. You should have at least a light blue and light silver spring minimum. Problem with locking it out, it’s going to hot start like a b*tch… unless you put the msd box ignition wire on a switch. Get the engine spinning then flip the switch… Any performance engine from mild to wild, you want as much initial timing as it’ll take without hard cranking. 👍

Nice to hear you know what you are talking about. I like people like this, because when they come to me, it's easy to look good. Good thing distributor manufacturers put those big heavy springs on to begin with so people don't hurt themselves. Lol

[@scottzito4797]

I just had a flashback to my high school Camaro. Are those real Cragar SST's or a good knockoff? Order

[@FamilysGarage]

Those are originals! They stopped making them in 2011😞. Took years to find. Still looking for original center caps….

Hello, In the video you mentioned at 65MPH the engine's RPM was 1800. According to the Tremec's gear calculator with a 3.73 rear end gears and 27" tall tires at 1800rpm your speed should be 57MPH. Did you calibrate your speedo? Are you sure you have the correct speedometer gear in the transmission? I assume your TKX 5th gear is .68. Maybe I'm wrong here.

[@FamilysGarage]

Good question! Our 275/60-15 NItto drag radials are 28” tall and the speedo is old 😜, but it was somewhere close. I didn’t pull up GPS and verify….

[@Danno74Z]

Did not know you were running the drag radials. I put in 28" tall tires and the calculator came up with 59.12mph at 1800rpm. Just a heads-up just a little off. Best to be off in this direction then get a ticket especially in a 20mph school zone.

[@FamilysGarage]

@Danno74Z thanks for the heads up😎🤟🏻

[@Trebor-gw8lt]

What’s it locked out at 32?

[@FamilysGarage]

we stopped at 31.
