- With before and after video footage of my 1974 Z-28 muscle car. Other items changed were; spark plugs and a larger mandrel bent exhaust system. The above added 25 to 35 more HP and increased Torque at the engines crankshaft.
According to my Moroso Power Speed Calculator this should lower 1/4 mile ET's by close to 0.5 seconds depending on, Track conditions & "IF" the tires will stick/hook-up.
The car had no traction problems before this mod. Now It goes up in smoke during a launch.
I'm running 91 octane Non Ethanol premium fuel. GM recommend a minimum RON octane of 93 leaded fuel. this would require 100 octane racing fuel. This would allow the engine to run 38º total timing advance above 3500 RPM without knock, I had to reduce TTA down to 34º to prevent knock (detonation) and dieseling... - Навчання та стиль
"When bench testing this do not get close to that plug or the plug terminals, a 35K V coil hurts pretty bad, but a 50KV coil 'll knock the fillins out your teeth, you'll know quick why to never do that again" LOL. You sure do know how to get the point across. I could work on cars all day with you. Thanks for the video on this.
Haha this is my childhood. My Dad and Brother tinkering around with stuff that I had no idea what it did, but I loved them doing it. They would cuss and fuss when things went wrong and they would make me feel a part of it by fetching whatever they needed and telling what the tool they had me hand to them did. So you fathers of young girls no matter how young include them in what you are doing. The time I spent with my Dad and Brother are precious memories for me now.
Thats great, My youngest daughter changes her own oil & minor plumbing repairs...
@@007bondjb That a girl. I know you are proud of all your children (It's in your voice when you talk about them) and the family you and Mrs JB worked so hard on. You both gave them the tools they needed to be able to take on this world and pass it on to their children.
We did our best, some things they just refused to learn. But I see that in everyones family. I hated history and math, just barely passed the classes. The problem was the teacher wasn't that good at all, matter fact, they sucked! My parent hired a private Tudor. After one week he told my mom that I could do collage level math with ease. I just had an attitude against my teachers and didn't care for their style of teaching. my priorities were playing drums, fast cars, pizza and girls. Matter fact, they still are... LOL
@@007bondjb But now you are down with only one girl to chase, you can make your own pizza, still drive the car everybody envies, play your drums as loud as you desire. Reminded me of the song Bang the Drum All Day. ua-cam.com/video/gO17hN-YvBc/v-deo.html
When I get older they think I'm a fool
The teacher told me I should stay after school
She caught me pounding on the desk with my hands
But my licks were so hot
I made the teacher want to dance
Always learn something new on your channel
Thanks
Awesome stuff, sir. Very thorough and great information. I learned a lot!
Hey Boy, I'm a long time sub. Every video you put up helps me. thank you for all your info brother...
Thanks Jeff
Good job bro!
Tanks BB
Enjoyed the video!! I’d have to strap me some small chamber Dart Sportsman heads on it. You talk about wake it up! You could still run pump gas , I’m sure it’s a dish piston motor.
Dart heads are good items. By keeping box stock, its worth more on the market All L82's came with 9:1 forged flat tops, 2.02 valves screw in studs w guide plates, 4 bolt forged crank w windage tray and road course baffled oil pan.
Got a cool lean going on there.
Need to measure the mV output of the pickup while cranking. Can’t remember but there’s a minimum voltage spec. The permanent magnet inside often cracks and puts out a lower voltage. But just as important is the shaft and bushing wear. It doesn’t take much wobble to create an erratic sawtooth waveform for your module, especially if the reluctor teeth actually touch.
Heck yeah, thank you for the info.
Hey man what kinda grease do you use under the pickup coil, just wheel bearing grease?
I know you use dielectric grease under the module but not sure for the pickup coil.
Thanks for the help
Boys gona be in a neck brace from whiplash in a Z28 lol...my friend has a 73 z 28 350 couldn't get him to turn loose from it..can't say I blame him.in 5yrs when I retire im going all in on a 1965 Buick Skylark GS with the 455 wildcat.
Them Buicks was screamers. My mom had 69 Riviara with a 430. It had plenty of power. The 70 Buick GSX Stage 1 are worth big bucks. They have tons of power...
That things got that little old 350, in it ....right??
Correct a Gen 1 L-82 4 bolt Hi-Perf 350 engine
Where did you locate the pick up?
Used to be able to get Blue Streak from standard ignition, but I think they kind of done away with it.
Yes, Standard dropped the Blue Streak labeling
did you ever find the bud dry?
Nope
Shart to ground 😂 ol mmmm good
