Don Terrill’s Speed-Talk

Yes sir. Mike, I have purchased several cams from you with great results.I have used all the big name companies as well. Extremely happy with your products . Lifters as well. Yes, because of speedtalk. Also , pipemax and the package deals of interviews.... great listening on a rainy day. Grant klohn

For what it’s worth. I’ve assembled similar engines using the 1.0 mm/ 2 mm oil. They definitely have less blow by on the meter on our dyno. Usually about 1.5 cfm at wot. The thicker rings seem to hover around the 2.5 -3 cfm on fresh builds. Just my experience.

Sbc solid roller profile. I can’t seem to I’d this cam. Any help would be appreciated. Thanks guys. I tried to upload a picture, but the file is to large. Here are the numbers

I know a pic would help. I’m working on it

I agree with all Toyota’s engines are not created equally for sure. Anything with an iron block that Toyota has is usually the engines Toyota built they’re good reputation on. It seems the newer stuff with aluminum blocks just don’t have the longevity. For instance , the older 4 cyls and v 6s were g...

To answer your question, i wouldn’t, as stated above there won’t be any load on it to break in the rings etc. Once on a dyno, you can tune it with widebands bank to bank quite accurately for cruise, part throttle etc. As well as wot. There will always be some slightly lean and rich cylinders as we k...

Nope. Can’t see that happening..

I have personally repaired a lot of these engines. I’m a Toyota master tech. I can tell you with all certainty, no amount of additives are gonna help. These pistons and ring assembly’s are glued with carbon/oil deposits. The new rings supplied by Toyota are far different for the repair. 3 piece oil ...

As I understand it they maintain the a/f ratio for emissions and get fuel economy with egr. EGR isn't used anymore, cam timing is played with instead. Alter exhaust gas residuals with exhaust timing and alter intake timing to change manifold vacuum (or lack thereof) to reduce pumping losses, and dr...

X2 for the results and am also interested with the headers. How much mismatch at the port with the small primary? Tri-y or long tubes, stepped? Collector length and diameter? Do the specs agree with Pipemax?Was there a down turn from the port or more like dyno/ boat/ Hotrod headers? Just curious as...

I would have liked that info but our fuel flow meter was on the fritz.

The headers were a hooker 1.5 diameter primary designed to fit a mustang ll. They turn off the head immediately.

I was pleasantly surprised also. I thought about 1.3 per inch would be the norm for these type of street engines. We were blessed with accurate o2 sensors for a change on the dyno, and ended up with a 6 jet size spread to get them as even as possible. This was with a crappy 12 by 3 inch air cleaner ...
