WE MAKE SERIOUS PONTIAC HORSEPOWER

AND WE KNOW MORE ABOUT BUILDING STOCK PONTIAC ENGINES THAN ANYONE.

This excerpt is from the 3/02 Hot Rod

All these experts hanging around and no one can change jets. ?

Full road test eh? No wiper motor. And a vacuum pump on a street engine?

So we're not saying it's a loser - we're just saying that a King Street 455-87

kicks it's ass for much less money! Without using a 4.250 stroker chinese crank. Without using

the MUCH heavier thus useless 6.800 length rods. (And without a vacuum pump.) And using 87 octane.

When asked about the true static compression ratio which was reported to be and we quote, "9.2 to 9.5"

(? Which is it?) Anderson lamneted to Bruce loudly in front of a bunch of neophytes that "everyone knows the Edlebrock heads are really 92 cc's"

We've been through 4400 sets of Edelbrock and we've never measured any that big.

At 87 cc's and a 4.250 stroke - zero deck 5cc valve reliefs and a +.030 bore you'd have 10.55 Cr.

Even if the excuse laden apprentice Dave Anderson was correct - 92 cc's still yields 10.05 Cr.

HERE'S THE DEAL

INCORRECT INFORMATION - DELIRIOUS HYPE -

ALL INTERFERS WITH REALITY.

TEACHING PEOPLE WHAT'S REAL IS A CHORE

WHEN EDITORS OF CAR MAGAZINES

ACT SO IRRESPONSIBLE.

We prove every thing we state.

And we've had professionals validate our results.

N.H.R.A. and the Westech Dyno Facility.

and thousands of happy customers.

Until Bruce is reinstated in one of the magazines as

tech editor - you're best bet is to call or E-mail him.

Here's another perfect example of the ongoing ignorance.

This tech answer appeared in a

well known mag.

The person that answered this question simply looked in an old manual

and went from there. They never saw an engine go to zero oil pressure and

"perform flawlessly." (Not for very long anyhow.) An extremely irresponsible

statement which would lead a Pontiac engine owner to believe that their low oil

pressure is ok. The correct answer would have been as follows as answered by Bruce.

"Anytime anyone asks me this I cringe. Because it leads to two questions which most people

can't answer, and then they get worried. Barring another non-typical problem, if your oil pressure

is that low your rod and main clearances are too big. We don't care what the factory manual says.

That's the first question I ask, Do you know what the actual clearances are? The answer is usually no.

Part of the reason I got into building Pontiacs is I realized there was much confusion when trying to

get an answer from a so-called expert. The confusion still exists today because these nitwits are still around

giving the same advice from twenty years ago. You obviously have a 40 pound pressure pump. Which is ok, but the clearance are more critical with that pump. When you begin with bigger clearances you lessen the life of the engine. A simple example. Hold a hammer one half inch away from a piece of wood and hit it.

Now hold it three inches away and hit it. You're going to have more wear on the spot that gets hit harder.

Your crank is the hammer. Your bearings are taking the hit.

We keep our in house tolerances at .0015 to .0020 MAX on rods and mains.

There's NO reason to have a race engine with tolerances bigger than .0020 -.0025.

Your problem is only going to get worse. As a band-aid I'd install a 60 pound pump in it now.

(Answer to the second question.)

There are a couple of other potential problems to eliminate. When you remove the oil pump, carefully unscrew the 13/16ths cap plug and remove the spring

and ball onto a clean towel. See if any foriegn bits fall out. If so those bits may have been holding the ball

off its seat which will drop pressure at idle. Look at the seat to make sure its not damaged.

Sincerely,
