Thank you guys, really appreciate it. Fantastic shot there john! Hopefully it's in good hands wherever it is.

I hate to ask this, but Jon, does this imply it is absolutely known to still exist, or is its existence still questionable at this point?

Any other pictures? :D

Ahh I see, those are no ordinary Torque Thrusts! Those things were born to run!
Thank you very much for the reply. :)

It's like taking a great tasting cake and ruining it with mud flavoring.

Why would you take a car that looks and probably drives amazing and ruin it with some tongue-in-cheek "faux" pedigree? That car doesn't need to pretend anything to be awesome.


NOTE: Engine looks trick, but they could have done without the suede/Alcantara dashboard and door panels.  :(

Can you give some specs on your wheels and tires? I have been confused about what kinds of old school wheels are actually strong enough to race on, and you are running the exact wheels I love the most...now I just need to know who makes them!
Thank you so much.

Man you have some incredibly unique stories! Thank you for the clarification by the way.

Could you get that picture link in your signature to work? I'd love to see the pictures of those cars. :)

VERY interesting. Not to say I am experienced, but I have never heard of only running the top ring! Thank you for the wisdom and effort, always good to hear more.

Very interesting, and I always suspected what you mentioned about investment being a factor. I'm actually quite surprised that most of these owners are OK with letting their cars be put around the track like that. But I also think that it's wonderful, and that these cars are doing what they were born to do!
As an aside, what happened to the Penske camaro(#16) last year is a good reminder of how much risk those drivers and cars are put under.

Thank you for the input, I'm actually assembling an old 350 right now! It's a low RPM motor for a '67 chevy C50(two ton truck). But it is also my first real engine work in a few years, hopefully I don't screw it up!

I really take interest in this part,

WE fired all our engines, broke in the camshafts for 30 min, pulled the oil filter cut them open checked them, put on another filter ran for another 30 min and pulled it, if no large or excessive metal shavings were present they were ok'd going to run the normal race schedule, perhaps that evening.

I always wanted to know how soon customers were allowed to race on their brand new engines, and this is exactly what I suspected. Break-in→thoroughly inspect→RACE!
(not any of this "go easy for first 1000 miles" crap)

last time I saw it it was stunning... Sharp. But not fast. 

What exactly do you mean by "not fast"? What is making it so slow? Thanks for the info.

So if the traction bars were considered to bind suspension, what were used instead, do you know Jon? Do the horizontal shocks do a better job than the "simple" traction bars? Thanks for the info!

What if you have a Windows operated computer?

Thanks for the link Jon, and also the hard work from Steve!

Thank you both Gary and Al, very cool especially coming from two people with "independent" backgrounds. Much more practical info for me and most others in the future.

Wow, that is very extensive and useful information! Thank you very much Gary!
Do you know how long Bob ran his engines before he ordered a rebuild? Because he was an independent driver, he might have just ran them until they died, rather than have them on a schedule for teardown like a heavily funded factory team.

That would obviously be the way I'd have to do it as well, not to mention the fact that any engine/car I would run would only be tracked once ever month or so, and street driven the rest of the time.

Again, thank you very much.

Trans-Am Camaros / Breaking-in of Race engines?
« on: August 25, 2014, 05:12:29 AM »
First off, I've only rebuilt one engine, and assembled one other. I have had quite a few years since then to read and ask mentors and learn about building engines and I always recollect the essence of breaking in an engine. NOTE:"Full" rebuild done in well equipped machine shop at local college--did any/all required machining myself. Very neat experience, indeed.

I have come to understand--either correctly or incorrectly--that camshaft break-in is tantamount. There is also a method for "setting" piston rings. These two methods are done upon immediately firing the engine and immediately driving the car, respectively.


However, there seems also to be one more step of break-in, more of a rule-of-thumb "grace period" type break-in for the engine as a whole unit.  Typically it goes something like, "drive 500 miles, then replace oil/filter--do not exceed 3/4/5000 RPM;limit/avoid use of Wide Open Throttle" That is a pretty general description.

So here we have a minimum mileage requirement(most say 500-1000 miles), AND we have a performance limitation: most tell you to not push engine hard, and keep RPMs low for duration of initial break-in mileage.



So what did race teams do when they needed to race their engine like mad men the next day? I don't care if Traco or Bartz built your engine, or if it was Al Richards and his buddies ;D


What was the procedure to keep engines alive? I have a funny feeling Donohue didn't exactly take the Penske Camaros out for a 500 mile stroll the day before a big race with a new engine, nor did Traco do it for them.

So then what??


Did Traco/Bartz/independents just not care? I remember an article stating Penske engines were only used for a couple races before a complete teardown. Did they just break in the cam and then send it off to be spun at 7500 for eight hours and just say "screw it" to engine break-in? Is engine breaki-in only important to ignorant little kids like me who only drive on the street?  ???  ;D



Thank you to anyone who may have insight, and apologies for my long-winded-ness.
