Re: Fw: My 67 valiant

I thought the "Polyheads" on these lists might enjoy reading Jason's comments on the mild 256/.435" Poly cam I sent for his cool Valiant; a link to his video at the end of this thread.\

Great! Now you know why I like these motors. The 318 Poly will REV to the
moon in stock stroke form, and seemingly well-beyond the cam profile's RPM
Power limit. I cam I sent you is what we call "Little Big-Cam" and is the
1957 dual quad grind with some "improvements" to the original profile.
Trucks have used this cam with outstanding results and have beaten NEW RAM
and other brand pickups in various off-road races...

I just send one of my friends a "large" solid Poly HP Cam along with a set
of ported Poly heads as he wanted to go to the next level (faster) with his
hot '64 Poly-Powered Polara. He did a few test runs and said he could
barely hold the car with the power-braking method; it wanted to launch with
his 3000stall convertor. When he let it go, he said the engine spun quickly
to 7500RPM and was still pulling..."WOW!" was the exclamation in his e-mail
story to me as well. The cam profile is 284/.510" (242@.050")110LC. As
expected, with only a Poly motor, there is no lack of "bottom-end" with this
cam and Rich's engine/driveline package. Usually a "large cam" trades upper
power for a reduction in low RPM power/or torque, but not here; he says
appears to idle much smoother "down low" but this is also due to the ported
heads superior breathing and subsequent increase in both HP & Torque under
3000RPM.

A Stroked Poly has the best of both worlds as well; only like being on
steroids. It doesn't behave as a typical stroked engine. The 390-402
Stroker Poly will REV like a small block and make power like a big block;
you should hear them on the dyno at 6000-6500RPM...they make music; much
like a HEMI. I have all the Stroker videos but the files are usually too
large to send over e-mail but I will try to send you one of the smallest
files.

You mentioned the GMC V-6 style of torque inherent in the 318 Poly; you can
check out the 390 Stroker Poly dyno sheet of Jeremy's motor and see the very
high & flat HP & Torque curve that just hangs high and flat like a deisel.
Note the "average" HP & Torque levels; 428ft.lbs.TORQUE from 3400-5400RPM
and 375HP from 3700-5700RPM. Even though the peak numbers are impressive at
412HP @5500RPM and 438TORQUE @ 3900RPM, it is the unmatchable high/flat HP
& Torque Averages over this broad 2000+RPM range that will allow you to
"take-on" the guy with a motor boasting much higher HP numbers as you will
take him off-the-line and your inertia will put you at the lights before he
winds up to reach his "peak" power; this is especially true against the
Chevrolet small blocks.

Bottom line, in either stock stroke 318 cid. profile or "long arm" Stroker
versions, the modified Poly engine is unarguably your best choice of
indigenous powerplant for the 450HP & 450 Torque and under requirements.

Anyhow, keep me/us posted on your adventures and let me know if I can
forward this post to the 62-65 Mail List and the 318POLY Yahoo list.

Wow . we flogged the poly Saturday and I must say I was supprised. That
thing will wind up fast and tight. We tightened up the air door a little on
the carb .otherwise it is just as you shipped it to me. Runs very well not
too rich. And did I mention will swallow the 750 carb at 1500rpm in third
gear. Gulp and gone!!! My friend that is helping me tune it was like see
if you can dump the 4 barrels at 3 grand. I shoved it into 3 and nailed it
at 1500 and said like that? He was dumbfounded we normally only play with
big blocks and we think small blocks are sissy motors. But I think this one
has monster torque down low. Drives like a gmc v-6 think 1960's v-6 I
have a 401 magnum google them and you will see what I mean. But they will
pull down to 500 rpm and keep pullng. This is the same way. Wow!!

Jason,

Yes, 3.91 gears are too steep for that camshaft as well. That cam likes
stock to 3.23 gears for effortless driving on the freeway and in-town
traffic. However, you do have a bad 3.91 gear set which clouds the issue.
Sure, whenever you are ready, I have all the cam profiles to suit your
taste. A good street/strip combo for your car, much like a 340 setup but
stronger, is the 264/.450" (222@.050") 110LC solid cam profile or its
262/.460" (214@.050") 110LC Hydraulic counterpart; I attached a video/sound
byte of the 262HYD. cam for your smiles...nice.

SO IVE GOTTEN TO DRIVE THE CAR ABOUT 6-8 MILES NOW. AND MAN DO I HATE IT!
THE 391 GEARS ARE KILLING ME. THEY MUST BE WELDED CAUSE THERE IS NO GIVE
WHEN I TURN AND THE REAR END HOWL LIKE A RELLY BAD HOWLER. O WELL JUST
MORE KINKS TO WORK OUT THE EXHAUST SOUNDS GOOD. USED CHAMBERED MUFFLERS AND
2" DROPS INTO 2-1/4 PIPE. COULDN'T GET ANYTHING BIGGER TO WEDGE UP TO THE
MANIFOLDS. WINDS UP NICE. NEED TO DIAL IN THE ALIGNMENT ALSO . WANTS TO
EXIT STAGE RITE. REAL BAD!! BUT WHEN I GOUGE ON THE GO PEDDAL AND ROW THE
GEARS IT REALLY JUMPS. AWSOME!! CANT WAIT TO GETE THE INTERIOR FINISHED TO
QUIET THE INSIDE UP A BIT. ILL GET SOME MORE PICS FOR YOU SOON. DEFFINATLY
SHOULD HAVE A BIGGER CAM. NEXT TIME!

Jason,

I love the look and paint color of your Valiant!!! What a great-looking
car! Man, that Poly under the hood looks like a Big-Block, only better!

The engine sounds "healthy." We call that 256/.435" (208@.050") "Little Big
Cam," because it runs soooo good for a small cam with very modest specs.
