What happens if a flexplate/flywheel gets messed up?

First it won't get messed up in my car, you will also noticed I used a very light flexplate. Now lets say it did get messed up some how.....I'd match balance it.

You would need to add weight not remove it for a neutral (internal) balance
It can be done but extremely expensive option. It is done by installing Tungsten (Mallory metal) to the counterweights which is not fun....
It would cost you in the neighborhood of $600 to $800 to do that with a factory crank,
Done like so

You mean to tell me you don't like putting 8 sticks of metal in a GM cast crank

Not sure which questions are yours, feel free to ask and I will answer.

Do you think that could work on a cylinder head? I have a pair of Merlin steel heads that torched between chambers. I think that was how it was attempted to be fixed. It looks like it still needs help.

I guess you could use the old one as a template on the new one to see what was done to it?
I have a question.
Have you ever put a stock crank out of a block on the balancing machine with the weights of the old rotating assembly and see how far off the factory was with the weight's on the balancer/flexplate?
They have had to just came up with something "close" to being balanced.
There's no way they did what you've done to every engine.
I know it's kinda pointless and not very economical from your stand point but just wonder if they were even close.

Re: How Its Built

Ah my fault it was Vid 9, someone was being a turd and I was trying to challenge him/her and understand at the same time. Reading what you all have posted since then has cleared it all up for me. Thanks again, and I love the series!

Re: How Its Built

Mark, I think this series was a brilliant idea!
It shows what a picky sh!t you are and how meticulous your work is.
It also shows just how much work it is to build one right.
I think there may be a few guys that will try to follow all your steps and build their own. If they do everything correctly, they'll end up with a great mill.
But even more, I think most guys will see how much work it is - work they don't have the time, tools or skill set to perform themselves - and they'll pick up the phone and call you.
Well done, Mark!
You are a definite asset to this site, glad you're here!

2. OVERACHIEVERS that are there to do the best they can, and will work on ALL aspects of their car to do it, no matter what. Late nights, skipped meals and important "family" stuff. These are more of the heads-up guys.

VortecPro falls well into the second group. He knows what works, and usually what doesn't. helps you out, lends a hand, and points you in the right direction.

I've SEEN a similar build, not as nice, run 10.30 @ 130 YEARS ago @ 3600lbs. It didn't have the head work, but a 11.8 to1 468, 781 head, 650 solid Ft cam, 454R with a 4500 carb, IN A STREETCAR with 4.10 gear.

Now not sure where he plans at running the motor, but to be quite honest, I would be shocked if the deal went 10.30's or slower. I'm figuring on his car being 3500lbs.

Can this deal run 9's is the real question. Knowing what his work HAS done, it very well could. I too am not affiliated in any way with VortecPro, but I am a big fan of his work, and it does produce what he claims. PERIOD!
Hang around guys that run NHRA Stock Eliminator. What seems down right anal to most Hot Rodders is the difference between running right on the index and running 3 spots below it.

The same attention to detail that Mark's engines display can be found.

Here is a link to what can be done with "Stock" parts.

NHRA Stock Eliminator - Chevy 427 - Super Chevy Magazine

This is basically the same engine we ran in APBA Super Stock Class back in '70's.

'67 Chevelle Malibu, Catalina Blue, 540 inch Rat, Air Flow Reasearch 290 CNC Heads heads, Custom Hyd Roller, .675 lift, 234, 244 at .050, Lemons Headers, Holley Multiport Fuel Injection, TCI 6X 6Speed Automatic, 12 bolt Posi Eaton TruTrac, 3:31 Richmond Gears, front and rear power disc brakes, Global West Suspension, etc.

I've been looking for a MUST BE '69 Vette. Either Stock or Superstock car, or a stocker even to build into a A/S like Joe's. I prefer roller though and Joe wanted to sell the package.
Sold my B/SA '69 427 Vette in 1983 to Mike Trumble, Sr for $8500 complete at the U.S. Nationals. That price would be great today. Sammy Pizzolato has it today but it's a lot different now than it was then (much more liberal rules now in "Stock" classes).

Keep them coming

I'm going to stop by the shop this week. Have a set of new AFR 315s I'd like you to prep for install and hopefully talk cam selection.

If you order an engine from Mark and follow along by phone during its process you will understand why these engines make the power they do. Mark is a no nonsense guy and told me the year warranty is even if I take it to the track every week and run hard. He wants these 467/620 engines on the track. A car set up for this engine can break 10 sec. But if you slack on your end that does not happen. He told me my car set up as it is can run low 10's with practice and the proper weather.
What set up would a car need to break 10 seconds with your engine?

How is your car set up now to hit low 10's?

What is the weight of your car with you in it at the track ready to race? L J

And boy, if those shop carts could talk.... Bet they have seen more big blocks than I could count

Re: How Its Built

Mark's engines are truly a work of art-and are amazing runners. After he built the 468ci/468 horsepower and 530 ft lbs of torque for my nephews Chevelle, I got a call from a Team Chevelle member who has already posted in this thread...asking me what we thought of the engine-as he was contemplating purchasing one. I told him to go for it-he wouldn't be sorry!

During break in, my nephews Chevelle got almost 20MPG on a trip from Phoenix to Tucson. The engine is running a cast iron manifold and quadrajet, hooked to a 700R4.

Also, the guy who worked on my nephews Chevelle was so impressed with the build (he's had at least 10 of his builds featured in Hemmings Muscle Machines-with a few more "in the can") that at last count I think he's had 3 engines done by Mark so far

Another friend should be contacting Mark shortly....THANKS MARK!

I am well aware of VortecPro's abilities in engine building. I also am aware of his abilities in setting up his car to run his engines.

VortecPro sells engines, the name of the thread is How Its Built. A lot of people will see this thread and read that your car can run low 10's with this little 467. They are learning how the engine is built, but when they see it will run low 10's in a customers car, it will let them know that they can probably do the same,, but they do not know how your car is set up, such as rear gear, suspension mods, tires, transmission mods, converter size and stall, fuel pump, carb, ignition ,etc;

I figured VortecPro has a lot of confidence in your abilities with your car,, after all, you are MrPaticular,,,so I think it would help VortecPro furnish engines to people who are looking for people they can trust, to purchase from.

But added to practice and weather, is weight. L J
