Don Terrill’s Speed-Talk

I think if it were me I'd retard it 2° with the gear and run it. It's an LS going into a Nissan. I don't think torque will be negatively affected and in fact it might help the car's ability to get moving.

Mal, I think for your peace of mind that's the way to go... Sorry Mate.

If the ex valve were not still open near TDC like it does on something like an air compressor it would make a significant difference. While the ex valve is open, CR won't make much difference. I'm involved in the discussion with RAMM. I happen to share this idea. Technically, if the exh is working ...

My first question would be for what usage? Is this a race truck or is this a street truck limited in suspension and hood clearance? In terms of "cheap"... Mopars generally are a little more than your BBC of the same power levels. You would be able to make that kind of power from CNC ported...

I'm just trying to get a better hold on how these work and how to take advantage of the fuel type. So far, I know it has less btus by weight, equivolent octane is something like 104, they like cooler thermostats, and on cams you want a wide LSA and exhaust lobe timing is crutial. So what else? Is th...

Being that I hate changing oil, I dont do it "within recommended intervals". But I loved to Wix Sport Truck filters too. I have noticed the HD truck hydraulic systems require 10 micron filters. Too bad nobody takes that media and puts it in cans that fit passsenger cars.

You can suggest it. But he does it all the time. It gets irritating. One of the most brilliant engineering physics minds I've had the pleasure to read, but an ego I would expect out of a spoiled son of a king.

You "Have a nice day too" Panic.

If they want to make the whole thing relevent and viable again, they need to make some big changes. The first thing they need to do is put a knock sensor on every engine, and deduct points for every knock count. The next thing they need to do is stop allowing stupid crap like half inch thick head g...

Those brushes are the last step where I get my stuff done.

Sorry Putz, I was referring to the 451 (440+.060) engine "experiment" i have on the stand still unassembled. That was the start of this thread. It was in pcs when I first posted the question, and has only collected some dust on the cover...lol.

I havent checked back on this in a while..and the stupid "mule" is no further along thatnks to other work. But interesting how polarizing the issue is. Thanks Panic. Am I correctly summarizing you when I say "it's hard to prove as the direct positive influence because there are too ma...

Well, I cant do the work the masters here do. I'm not equipped or do it for a living. But if you want and need basics, go take a couple physics classes at your local community college. What make heads work, makes everything else work. If you know the theory, it applies to everything you do. You may ...

ok, you're all above me on this, but I'll toss an idea. since you're spending all the bling. What about a block module, and replacable single cylinder sections. Tink an air cooled VW cylinder surrounded by water, inside a larger block. I'd use a flat 16 design, 4" bore, 3.75 stroke to keep fast...

Not entirely true anymore...Somebody has a kit to make an LA version Hemi. Using brandy new hemi head castings just for them. Seems like a big waste of effort to me, but somebody must think different. There were pics and a link I think from the last SEMA show with them. Looked too much like a 392 fo...

So I've read some articles, and seen the posts here regarding cutting the hcannels radiating out from the plug area thru the head's quench area. I'm currently playing with (still in mockup and fitting actually) on a BB Mopar 4.38 bore engine, uzing quench dome pistons and opwn chamber heads. These h...
