Big blocks were back for 2005 with a limit of 509 cubic inches. I had a customer that was
interested in a street engine with obscene power so I decided to see if we could do the David
and Goliath thing again with as good of results as the last time.
Since no one makes a crank for a Buick I had to have a custom billet made to my
specifications. I just barely got it in time to build and dyno the engine but that is another story.

The results of the contest were as follows as reported by
Popular Hot Rodding Magazine

Dyno #3 #32 -- Automotive Machine & Performance -- Philot, KY

Mike Phillips brought one of the best-looking engines to the challenge yet. However, Mike
didn't bring out the stout Buick to win a beauty contest. He made the hike from Kentucky to be
a contender in the 2005 Jeg's  Challenge. After his warm-up pulls Phillips and his crew
chose to keep the engine running while making changes, including the high-speed air
bleeds. Mike contended "I want to keep the intake cool, so we keep the engine running while
making changes. Besides, if we drop one in we have another hand just in case. Mike has a
DTS dyno of his own back in Philpot and was happy with the results in today's challenge. "We
did some testing last Friday and our numbers today are just about identical as they were
back home". After the Buick made it's last Pull Mike commented, "hey, this ain't no dyno
queen, this is a street engine."

Average Torque                 Average Horsepower
Run#1 611                          529
Run#2 610                          528
Run#3 609                          527
Average 610.00                 528.00
Total Score 1,138.00  
peak Torque 672 at 5100     peak HP  713 at 6200  
Those numbers were good enough to place ninth in a field of forty. There was a lot attrition
in this years challenge as only 19 made it to Bill Mitchell's World Products headquarters on
Long Island NY.
Finishing in the top half of the field with a true street engine was a lot of fun even though we
did not run a roller cam or have the high compression that most of them had.

The specifications on the engine are as follows.
4.325 bore 4.325 stroke                        11.2 to one compression
AM&P race ported
T/A aluminum Stage 2 Track Eliminator heads
AM&P modified 1095 King Demon on an AM&P modified T/A SP 2 manifold
Custom ground "Flat Tappet" cam from Bill Metzger the "CAM WIZARD" at
Lazer cams
AM&P quench style reverse dome pistons custom made from JE pistons
6.800 Eagle GM rods   /   billet crank by Moldex
SRE / AM&P aluminum pan
Scavenger oil system  (see our Buick parts page for information)
T/A block girdle, timing cover, valve covers and related parts

2004 was for small blocks again but 410 cubic inch in size

For 2003's Engine Masters Challenge, Popular Hot Rodding Magazine decided to have big
blocks with a limit of 470 cubic inches.
Well since we had been building our Stage 1 Plus engines at 470 cubic inches for years I
just could not pass up the opportunity to make the trip to Memphis TN, to see how a real
pump gas Buick could compete against the more racy Ford's and Chevy's.
We were pleasantly surprised to come in third of 12 entries with a score of 1026 with a peak
HP of 617 at 6400 and 583 lbs ft of torque at 4700.
Only the dyno queens as I call them were ahead of us, Ford in first and Pontiac in second.
The best part of the story is that the engine that we had in the contest is still driven regularly
on the streets of Chicago. It resides in Steve Russo's pristine Blue 1970 GSX with A/C, power
brakes and the rest of the buttons.


2002 was the first year of the Engine Masters Challenge and it was for 360 cubic inch small
