Day 2 parts discussion

Here is my dad, Plowman's Nova circa 1971. Note his homemade slapper bars and how they were long enough to reach the spring eye then. I guess he was an innovator ahead of CE. The pic isn't great but look at Jed's bars for length and look at these.



I may be in the minority on this, but I do expect my Day 2 parts to perform well 1st and look good 2nd. I do like the challenge of making some of this old technology work as well as the modern stuff. I also street drive 4.88's anywhere with dual quads which isn't the norm these days either.

Thanks for the perspective Dave. I guess I've got to open my mind to this (new to me) idea of what is considered a Day 2 car these days. I might have to come up wiht another name for what I was thinking a Day 2 car was.

I don't think any of the old bars were ever under the spring eye. Competition Engineering was the first to push this idea back in the late 70's-the importance of having the bar under the spring eye-that was their selling point.

It does not really matter to be honest to me at least. Most of the &quot;Day 2&quot; cars are just for regular street driving and the occasional street burst/romp on old bias or even new radials no real harm is going to be done.

Now if you are on a sticky racetrack every weekend with slicks or soft drag radials and really pushing the horsepower there might be some concern.

These are more show than go anyway for the the majority of Day 2 cars. </div></div>

Paul, don't let me tell you how you should do your car. Everyone is different on this trend and that's fine.

I'm part of the school who take the old parts as is...that is how they were back in the day, design flaws and all. I was on JJournal one day and a guy with a 50's style rod was telling how his friend is building a hitech style rod and said he wanted it to ride just like a Lexus and of course everyone piped back ..&quot;Then he should just buy a Lexus&quot; in typical H.A.M.B.fashion with more.. let's say...salty language.

To me part of the thrill is experiencing how these cars drove back in the day, bias ply tires, braking, old style suspensions..all their little quirks. I guess I have the same thinking towards the speed equipment.

Funny, I would bet most of the old speed equipment performs as well as the new stuff when dealing with apples versus apples. Carb versus carb etc. Car Craft did an intake comparison several years back and the old 70's $50 swap meet Edelbrock/Torker combo made nearly as much power as the new fangled high $$$ latest intake of the same design. Not as much of course but on the street is anyone really going to notice a 6 hp increase? I'm surprised they printed the results.

Much of the new speed equipment is just rehashed old designs. The Edelbrock Air gap intake is basically the old mid 70's Scorpion air gap style. I would bet most people could not tell the difference on the street between the two.

Guys, I would most likely use the ones I have, if they are somewhat old speedparts? I agree that it's going to be a romp around town kind of car and not an all out every weekend drag car. I was concerned about the length on these bars only because I can see a bow, in the opposite direction, in the leafspring. Heck, I have no idea how long those bars were on the car before I got it? And who knows how old the springs are?

Either way, I can understand the engineering concept of having the snubber under the spring perch.

I'm going to take the wheel off this week and take pictures so I have some idea of what brand they are. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img]

And some of the Stock eliminator guys still run the old slapper bars with pretty good success. Benny the Prof's BB nova runs 10.50's with the old slappers so that is good enough in my book.

I run the old style of drag racing. Foot brake only. With lots of day-2 items on the car. Thats what makes it fun. We all ready ran a 1;49 60 foot time, at 129 MPH. And thats leaving the line at 1,700 RPM;s. Thanks BBBenny [img]<<GRAEMLIN_URL>>/[/img]

A guy in my hometown won his class record 5-6 years back on the IHRA circuit with a FAL orange fiberglass fan and a old Accel Dual point. Not sure if they are still on the car or not but the old stuff does work.

Those old Accel 31000 dual points were very well built and precise.

Lakewood still sells the long bar and the short bar for 69 Camaro. They just warn not to use the short bar for mono leaf.
In many of the original pics (1967-1970) the Motion cars and Yenkos used the short bars.
This may have been for better ground clearance as there were still a lot of dirt roads and drive ways back then where the long bars would bottom.
The slapper bars that hit the springs are not a great design either short or long. Most broken leaf springs I have seen brake at the front eye where the long bar hits and the short bar looks like it will arc the spring.
But I have seen old school cars with long bars and short bars that still have their original springs. I have an old set of Long bars where one is mangled from a high speed bottom out.

I've not seen this common failure. Do you have any pics?

Here is what I've seen:

Short bar:



Bent Leaf


Is this what you consider a long bar and the proper place to contact?
