Gary, The Poly engines and the slant sixes
are probably the two most common mass produced engines in Mopar history. I
would not be ashamed to be driving around in a nice Mopar with some Poly power
that has some nearly (except for the intake manifold) stock looking HP nearly a
stock Poly.
The poblem is nobody would believe me that a Poly
can run that well. Reality would have to get a grip on them sooner or
later. We might be down to bare bones, but there is a lot of undicovered
Mopar stuff still out there. Soon a Poly might be by fat the best value
for your dollar and nothing to sneeze at in the torque and HP departments.
Thanks for the pioneering work. You have shown people the path, now all
they have to do is take it. Its a lot easier to rebuild the Poly in the
car than to have to change the motor mounts, trans, drive shaft, etc., when you
put a big block where a small block use be. Enough power to impress
even chevy lovers (notice how I don't capitialize chevy. Or obama and some
other nut cases.

Chick,
The Poly head is an excellent design and you are right, only held down by
the stock configuration of the iron head for anything over 500HP but unless
you are building a car for ultimate Drag Strip Duty or must have more HP &
Torque than the majority of “Rodders” then I think it is the best bang for the
buck to build a Stroker Poly or high-revving stock stroke Poly. There
are “ways” to get the Poly to 600HP but if I did, it would only be to say “I
told you so...” but that wouldn’t please me. Bottom line ALL the Mopar
Small Block and Big Block engines are great performers with the right parts
and can be built for any (practical) level of HP and Street or Ulitimate Strip
Racing but don’t overlook the Poly and if it meets your HP/Torque goals at the
price point you can afford, go for it; and I will help where I can.
Check out the Dyno Sheet on my previous e-mail...and the engine specs;
quite a conservative build for the output achieved.

Gary,
You have a heck of a story on that engine on the
web. I found one place that said the Poly chamber is better than a Wedge
chamber and more like a Hemi than a Wedge. The story also said it was a
shame that engine got overlooked in the speed shop dept. because there were so
many other engines to hotrod that the Poly got mostly overlooked by the speed
crowd. But some people, like you, applied basic HP and torque making
parts (even if you had to make them yourselves) and showed people a glimpse
into what a Poly was capable of. If you keep it all Poly you get choked
down by the heads and valve size, but you can make it better than stock, by
far.
Your info on the rocker arms is excellent.
I know Hughes aren't the only good rocker arms on the market. A few
years back a place called Diamondback Engines from Texas entered Mopar
Muscle's engine contest. Diamondback got bad rocker arm shafts from Comp
Cams but they had a spare set with them. They got another bad set and
were so upset they got DQ'd that they went to the Comp Cams factory and asked
what was going on. It seemed that Comp Cams farms out their shafts and
got a bad bunch in. Diamondback had the story on their web page for a
while. Then they got a hold of some Hughes rocker arms and their engine,
run on a different dyno, would have made second place if the Comp Cams parts
worked properly. That's what most of those guys use, Comp Cams rocker
gear and cams. Hughes makes only Mopar engine parts and their cams and
rocker arms, port work, everything, is just great. They will build you
heads any way you want them. Plot out an engine for a special thing like
street, street/strip, bracket racing and will test the engine on a dyno and
find out what works best. If you have the money. It always boils
down to that.
I'll tell my friends about those old Poly engines
and they will think I'm crazy...until I show them some of your stuff on the
web. It will be fun watching their eyeballs pop out.
Thanks a lot,
Chick

Chick,
The Poly 318 is like any other LA engine with the same production
variances in rocker ratios. Yes, the fix with the LA is to install the
blueprinted aftermarket Hughes (or other trusted brands) to get a true 1.5
or 1.6 ratio.
Mancini Racing has a nice write-up on the Hughes 1.5/1.6 rocker kit at
$479. The Poly 318 has a blueprinted rocker assembly available in a
non-roller 1.5 or 1.6 ratio with hard chromed shafts, fully bushed &
trued rockers, improved jam-nut adjusters...for approx. $539; a bit more but
not outrageous. The other offering is a nice set of hard chromed
shafts/fully bushed & trued OEM ratio rockers/with improved jam-nut
adjusters for $298; a very good deal and nice setup to replace the old-worn
Poly 318 rocker assembly with their loose or bottomed-out/weak stock
adjusters.
Of course, there was a custom run of full roller tip Poly Roller
Rockers done recently for some of our “adventurous” HIGH HP Poly engine
guys.
By the way, I think the 318 Poly is the best HP/Torque engine for
indigenous powerplants. Less expensive than swapping an LA or Big
Block into the 62-65 Mopar if you are satisfied with making and easy 400-450
HP and the same torque vintage motor. Realistically, it is hard to
beat the following stats on a mildly built Poly Stroker motor;
375HP Average from 3700-5700rpm
428ft.lbs. Average Torque from 3400-5400rpm
Nothing beats the simultaneous high/flat HP/Torque curve for the cost
outlay/uniqueness of this motor.

Exactly right, unless you use the "LA" style
318. The old blocks are pretty much the same but the heads on the
newer blocks (318) fit only the new block and the old poly heads fit only
the old poly block.
So performance mods are up to you on a pure
poly 318. However, if you use the other block so you can use the heads
then Hughes has rocker arms and shafts for the more modern
heads.

They don't have them for the poly.

This is why I keep telling people to get
Hughes Rocker Arms and Shafts. You get a true ratio of 1.5 or 1.6
(your choice), no needle bearings to break and they ain't free but are
worth the money. The stock rocker arms are hard shaft and
hard rocker arm. Hard on hard causes wear and
galling.
All I can say to anyone building a Mopar
motor (any size, small or big block) is take my advice, please (on the
shafts and rocker arms).

Hi Folks,
I thought I'd send a note to let everyone know what's going on
with LeRoar. I tried my hand at cam degreeing by first checking the
original cam. I found it only had .396" lift instead of .450". That
was due to the rocker ratio being 1.38 instead of 1.5 as
advertised. So I guess it's amazing it ran as good as it did
with such a small lift. I also installed the new cam and tested it on
#1 cylinder and found that I will have to wait for the new heads
before I can use the new cam. The springs will bind as there is only
.008" clearance at max lift. I'd probably bend a pushrod. I pulled the
heads now and will be removing the engine soon. I want to solve some
oil leaks and I think the front trans seal is leaking. I'm going to
leave the trans in the car.
I hope I will be able to race at our MidAmericanMotorplex off
I-29 at the Glenwood, IA exit. I-29 is closed both North and South of
it due to flooding. So far I think it's OK but I may have to
build a marine poly if the river keeps rising. Dodger volunteered to
transport LeRoar to the 1/4 mile track at Kearney, NE if MAM isn't
running. Kearney is a bit far to drive a car to race. One hiccup and
you have a long walk.
The Summer is beautiful, albeit wet. Get those Mopars on the
road.
