Don Terrill’s Speed-Talk

Goodson supply has one ( GCT-35) that has a range from 1/4” to 5/8” for 80 bucks, but I will bet that while your current one is still good if you send it out to get Cryo treated it will last a great amount longer! Your bet would be wrong. Cryogenic treatment isn't a magic bullet for tool life. I di...

I have been running a 55 GPM Meziere in my street/strip 67 Camaro for 16 years with no issues. On my old 770 hp 496 and now my 830 hp 555. 15000 miles, Hot Rod Power Tour, etc. It consistently runs 170-180 degrees with a 160 thermostat. It has never leaked. They are rebuildable, I left a breaker bar...

I used the JTR recipe on my 85 S10 Blazer back in the early 90's. I fabricated sliding conversion mounts that bolted to the 2.8 motor mounts based on their drawings. I used Sanderson shorty headers, a 4.3 radiator and dual flexalight fans/shroud that fit the core. Some firewall clearance was needed ...

Call Dan Lemons. He will be able to build a set from jigs that are already proven. They will fit beautifully and make good power. I couldn't be happier with mine, every time I look at them or change plugs I'm glad I didn't buy another set of catalog headers. Mine are for a 67 Camaro, 555 bbc with fr...

I ruined a perfectly good street 496 by doing a short fill and honing it another .010. Went from 170-180 degree temps to 210+. I added an oil cooler and it didn't help much and I started seeing bearing wear. Now I have a Dart block 555.

This stuff stays where it's put and mixes well with oil. It's my new favorite.

5k street miles per year in a 521+ inch engine? After chasing valvetrain issues in my 67 Camaro with a 496 bbc, solid roller with .842 lifters of a few different varieties and stud girdle setup for several years, I now have a new 555 with Morel .903 lifters and shaft rockers. No issues with the new ...

I wouldn't do it. I did a short fill on my old 496 BBC when I freshened it. Honed it .010 larger. The engine which previously ran 160-170 degrees would run at a minimum of 180 and frequently over 200 even with an oil cooler. It was a huge mistake and I ended up building a new engine with a Dart bloc...

If you have time to wait, keep an eye on ATI's eBay Store. I bought a new blem with only a couple light scratches on it for less than half price.

Why no tall deck? If you aren't married to a set of headers, less than 1/2" deck height increase won't make any difference. If I was in your shoes, I would look at the blueprint engines 632.

I am currently building a 555 for my 67 Camaro. Dart big M, ported Profiler 320's flat milled to 106cc with CP flat top nitrous pistons. It is at 10.06:1 compression. My cam is a Bullet roller 267/276 @ .050" .430"/.430 lobe lift with 1.8/1.75 T&D shaft rockers for .774"/.748"...

1st install a lockup TCI Super Street Fighter converter. Honestly, that should seriously drop your 60' and make it more fun to drive. If you want more after that, go with a deeper rear gear.

Talk to Dan or Brett at Harry Heads in Sioux City, IA. They will get you squared away, they do magic with the old bbc iron heads.

I bought this one: Found it on their ebay store and saved a few bucks. I love the accuracy and it will be with me for my lifetime.
