Don Terrill’s Speed-Talk

Come on, Mike, when are you going to write one? When I retire. I have a huge advantage over my competitors, and I plan on keeping it. This being said i would suspect that you supply at least a portion of the Camshafts inside the NASCAR Engines. Of course I know this is a matter that can Not be made...

Johnson puts together a lot of Isky's roller lifters but Not " All " of them. Isky's highest end Roller Lifters are assembled In-House. Who told me this, a person employed by Johnson in Taylor Michigan . Mark H.

No Mag, he said it would look Cool / spiffy in a Truck . Mark H.

Some things you never forget. Several years back i viewed a Cylinder Head in a Machine Shop that was in for something. I remember it being a Yates designed Ford Head from a Racing Engine. The Combustion chambers all looked the same being the color of light brown / tan, kind of a hot chocolate color....

20221203_182359.jpg20221203_180151.jpg Curious on what to look for and which direction one should take when looking at burn patterns. Spark plug wetting seems to be a issue for a lot of early OEM type cylinder heads. The fuel used here was MS109 I am interested in opinions on what guys think is hap...

Hello Comp461: Did the Block supplier disclose the Molecular of the Aluminum ? Do the Main Studs have an I.D. on them ? Just curious. I will say it looks pretty darn nice . Mark H.

I know dang well Mike Jones or Warpspeed can shed some light on my question posted @ Sept. 9th 8:24 . Mark H.

Here is a question i would like somebody to answer, the weight of the Inner and Outer valve spring ( the portion of weight that the springs themselves have to keep in control ) how does this weight compare to the Titanium valve, the Titanium retainer and tit. locks ? Mark H.

My wild guess / estimate would be that T & d 's Steel Rocker arm would flex only 3 to 5 percent of what the average Aluminum rocker would . Mark H.

MD383, the pictures of the spark plugs do not look lean to me " but " the only way to get an accurate reading on plug color is a high speed / RPM instant shut down, ya know what i am saying ? Mark H.

You said the radiator in use is brand new, how about a little history on this 327 engine. Is it also new or is it well broke in ? If the Engine is Not new, has this temp. concern been going on for a while or ?? .

Core size ?

It is in an area where there is a Lot of air flowing, Rough mark it, remove and saw it off a little long, clean threads so it does not ruin the threads in the head, tighten to spec. then grind to fit port shape. on final assy. use a small amount of thread sealer . Mark H.

What metal is your ( 4 ) core rad. made of and what are the " Core " dimensions ? Mark H.

yes, more than sufficient, i agree and that is why i ask him if the Camshaft was totally enclosed or not . Mark H.
