Don Terrill’s Speed-Talk

After many years of ignoring it we finally put up an new website.

It's not a shopping site.

If you have time please take a look and feel free to critique freely.


Thanks.

They're more than sufficient to the task.

the GT-40P or X heads are the two you should look at if you need to stay stock.

Eric and Shawn are familiar with them if you need to chat about them.

Interesting thread.

And I'm not a tuneup artist, so I have little to add on that front.

But....don't think of them as "pistons"...think of them as "fuses"....

Of the two 1/16.

You want to reduce the chance of flutter.

Pretty much the same as a lighter flywheel.

TRW got out of the piston business 15 or 20 years ago.......

The newer Federal-Mogul/Speed Pro's are made in India.

One of the bestest things that ever happened to me....

I'd rather see you use a Dart Sportsman...but, other than that, I'm with Duane. There is no magic that will make the stock block live in this application.

.150 at the bottom...way me than that everywhere else.

This is not something you should do.


Who is going to cut the pin hole....perfectly straight and perfectly positioned?

This is a converted stock block?

Not unless you screw the pooch on the tuneup. Mark: appreciate the response. What is the "right tune"? Do you go by EGT's, AF ratio, or what? I know about the idea that a tune that is too rich runs the risk of burning backward through the top ring groove into the valve pocket and may have...

Not unless you screw the pooch on the tuneup.

Assuming a forged piston .230 is fine.

With the parts you mentioned the piston will be in the hole .040 to .050

Just saying what my sorces tell me.

example:
When is the last time you thought you were buying a quality spring only to find out they changed and didn't tell anyone.

Valve Springs...lifters.....etc etc.

But I have top know for sure before I tell anyone.......
