But I'm the guy that just builds 'drivers' and wouldn't put big money in one even if I had a million$$$. Wellllll,,,,I might buy a 68-69 Z28 if I had that much and weld it down to a trailor

Hey,you get what you pay for.
Who knows you might just have bought eight good ash-trays.
Better mic. the skirts.

Eric,,,let me buy junk if I want to Hey,,,,I don't smoke,,,,but can you imagine how big all my buddies eyes would get when they see original equipment Z28 pistons on my living room shelf? ",,,YEAH DUDES, THOSE ARE REAL Z28 PISTONS"
Eric,I did already,,,is .300 difference from top to bottom too much?

it all depends on how well you know the machine shop guys

OK,,,I'll not be a smartie,yes .300 is way to much,,,probably even to keep a piston from breaking. These are acceptable for my use and won't rock n' roll seeing that the rings will last the mileage I plan before selling or throwing a rod.They have .030" difference.
But Eric has a point and seeing how I bought an OFFY 360 intake with striped bolt holes off that site I wouldn't recommend buying pistons. But the bolt holes are an easy $20 fix,expanded skirts or broken lands are not, but these came from a machine shop that wasn't wanting to unload them to get their money back,so I lucked out.

A star is born.
Judging by your clever responce I doudt you own or even know how to read a mic.
Just stay in the truck.L.O.L

Was just doing a little humor with those remarks Eric. But anyway,,,bless you! I don't have to argue.

I might have been a little harsh and for that I am sorry.
I don't want to encourge anyone to ever buy any used parts un-less they have been checked out by a good machinist/engine builder.

And then we go to the old thing of if you can't afford the time and money to do it right, when are you going to find the money to do it over....


Scooter, you've been lucky so far. But lets be real, here. How many passes did you put on the car last year and what was the ET???? \

Lets all make sure we are comparing apples to apples. I like to run either 8.90 or 9.90 Super classes, "just playing" is a 10.90 car. It's not fair to compare parts necessary to run a car with an engine that will live to the parts required to run a 12 to 14 second car......

my motor grant that dont have nothing for passes in 2 years, the old 301 before this one was ran every single weekend for 8 years staight, 10 passes a day average 12's r fun because stuff dont break as much

I would not be afraid to put a set of rings and bearings every now and then.12's? Like Dave said lets see some of those time slips.

aw your making me work, ill post them when i find them i have them stashed in the garage god knows we all have something stashed out there for safe-keeping.

i have seen those time slips and 12s all day long why change rigs let a compression tester tell you the truth
not say that changing them is a bad thing

If he was a bracket racer he would be replacing his rings,bearings,valve springs,touching up the seats and valves and checking everything over each and every winter.
With 7 years of racing I will bet he has "collapsed skirts" on more than one piston.
This is a little something I like to call "preventive maintenance".
If I had a dollar for every guy that walks into the shop each and every year wanting to know why his car keeps going a little slower every weekend I would be set.
I simply ask when was the last time you replaced your valve springs?
If they have to stop and think about it I know it has been to long.
I have several signs in the shop one sign says "If you want to play you have to pay".

On a high rpm small block, I believe I would be checking valve springs and doing a leakdown on the engine a whole lot more often then once a year!!! Those parts really take a pounding when you start running 7,000 plus rpm every pass... When I run a small incher, WEEKLY maintenance is a check of the valve springs with an on-head tester, run the valves, and a general checkover. I would usually do a leakdown on the engine every other weekend. It's a whole lot cheaper to catch these parts going bad BEFORE they break and take a bunch of other high dollor (or cheap leftovers) out the side of the block with them!!!!

As with any kind of racing, everyone wants to go fast, and few people are willing to do the work required to make the car go fast!!!! I guess there's a whole lot more glory in driving the car then turning the wrenches.....

Dave,we have to take baby steps here L.O.L.
You don't have a "snowballs chance in hell" to convince a guy to do this when he does not touch a thing in 7 years.
Lets get him convinced about checking all these things once a year and then we go to once a month and then every other weekend.
Sometimes you have to "take people by the hand" and lead them.
Scooter,if you are reading this take notes we are here to help you.
