Don Terrill’s Speed-Talk

Bill K rightly points out it will now be underbalanced, so say, "I had it underbalanced; better for durability, ya' know."

One option is just smile and tell anyone who asks, "I had it overbalanced; better for extended high RPM, ya' know."

A friend has a '65 327" 300hp, 40,000 mile engine and Powerglide, complete with PS and AC. Been stored in a sealed container for fifty-five years.

We repaired an antique which had spun its cam bearings. Bore the tunnel straight and oversize, press in and Loctite steel sleeves and drive in standard cam bearings. In our case, we lucked out and there was a Redi-sleeve exactly the OD/ID we needed. We trimmed it to length and left the flange on it.

To bring closure, we've done two of these now. For the first try, we shortened the BBC pins and cut snap ring grooves and honed the Packard pin bushings to BBC diameter. The second go-round, we bored the BBC pistons to BBF pin diameter, removed the Packard bushing and honed the small end to BBF pres...

It's a PITA to hone axle and kingpin parts on the Sunnen Rod Shop, but that's how we do them. The real PITA is trying to measure the ID to hold the fit you want.

Yes, thinner oils are a part of it. Also worth mentioning is temperature control. My Studebaker and Packard V8s are 700 pounds of cast iron, which takes a loooong time to warm up. There's more coolant in the heater system of an old school engine than in the entire cooling system of a 300 pound curre...

Yes, both tighter and more precise. We build obsolete engines and the Shop Manual tolerances are on the order of .0005" - .0025". An example, as late as 1956, the newly constructed Packard V8 machining line couldn't hold exact finished bore diameters, so each cylinder was measured and stamped with a...

Powerglide transmission with 327 and highway gears in 3800 LBS+ cars are kind of a tough cookie as you know. For true. I was there back in the day and if you had a 300hp 327", you were not top dog, but a bigger dog than most. Today, it has to stay in the slow lane and keep out of the way of the bul...

I have thought about having the tunnel line bored. But where I'm located, finding someone that's done it before to feel comfortable with doing it is the problem. Fortunately the owner of the engine understands the issue and is in no hurry. Doubtful you can find anyone anywhere who's recently line-b...

Since you're a couple of thou undersize anyway, have you considered having the cam tunnel line bored to size?

Thanks for the cover shot. The injected Falcon 170" appears to be a Hillborn.

Don't remember that one, but would love a link to read up on it.

I do remember the Bosch mechanical FI installation he did on the big Ford 300" 6-cyl.

How about several Harley side draft carbs ? Sportster carbs should be about the right size and inexpensive compared to SU's. I never cared much for the SU's. They have no idle jet and rely on adjusting the main jet position in relation to the needle for the idle mixture.This can be a problem gettin...

Well, it's moot. He's decided to go back to the stock cam.

I've always wanted to do the IR intake, so maybe I'll buy his takeout cam and have it on the shelf if an OHV Studebaker 6-cyl build ever shows up.
