I would agree with Dodger that the 360 can build easy HP as the recipes
are numerous and you have any shop that can do the build. However, you
need
to determine what your real goals and intentions for your car is. Reading
your e-mail lets me know it is an “original” car so do you want to have
the
original look with a wallop packed under the hood – ala, sleeper? How
much
HP do you want vs. what you really need to lose traction on the street
with
Drag Radials?
We can only give you our opinions as to what we would do but we know what
kind of car we want to build.
Saying that, I will give you my opinion and best guess as to what you are
looking for in your build; pump gas engine with enough HP and torque to
smoke the tires at will but not unmanageable street manners – it must
start
easily, not require extensive tuning to maintain driving pleasure, not
require more than 3500rpm stall convertor and a 3.91 rear gear...a nice
looking, hard running, sleeper car, with that nostalgic 1963MOPAR look &
Hot
Rod stance (perhaps aftermarket rims and 235/.60-14 or 15 Drag Radials;
Hoosier/BFG/MT) enough mods to stay within your budget w/o compromising
your
“performance.” Need to assess your true street to strip driving ratio as
well.
I would choose the 318 Poly in Hot Street modified form or a 360 Stroker
Poly.
Reasons:
No expense and hassle of buying a 360 core engine and changing the motor
mounts and swapping to an externally balanced convertor for the
externally
balanced 360 engine.
The 360 is ubiquitous (everywhere/common) and doesn’t look
“right/correct/or impressive at all” in the engine bay of a 1963
Plymouth”
and will maintain or increase the value and or desirability of your car.
It will also “personalize” your car...think about what that means to you.
The 318 Poly is impressive looking (wider than a 440) and appears
correct/nostalgic/generates more attention & questions than a HEMI in
your
engine bay...that really is worth something at cruise nights...
“ “ “ will not require any chassis modifications other than to
replaced the old parts – no modifications/adjustments to anything.
“ “ “ High Performance parts are all available and easily
obtained new except for the intake manifold and there are plenty
available
on E-bay and swap meets to make this a non-issue; especially the dual
quads.
The 318 Poly will meet and exceed all your HP & Torque goals without
exceeding your budget and easily make 425HP and 450ft.lbs.torque in 360”
econo Stroker trim and 350-375HP in HOT stock stroke trim.
NOTE: read Nick Tiberio’s e-mail comments about his 360 Stroker Poly I
forwarded to this list and question some Poly builder/owners about the
pros
& cons of their “built” Polys vs. other options.
You don’t need more than approx. 350-375 REAL HP to reach your goals
outlined in your e-mail with your chassis.
HOT Stock Stroke Poly:
OEM pistons with head mill to achieve 9 to 9.5 to one ratio; 10 to 1 can
be had as well.
Port & polish the heads – 211cfm intake is enough flow for 425HP and
450ft. lbs. of torque; this with headers/exhaust gives you the most bang
for
your buck with an aftermarket camshaft and four barrel induction.
264/.450” (222@.050”) 110LC solid to 262/.460” (214@.050”) HYD. HP Poly
Cam; or 284/.480-.510” (240-242@.050”)108-110LC Poly Solid Cam to
270/.480”
(230@.050”) 110LC HYD. HP Poly Cam
Four barrel intake or dual quad
Stock 1.84/1.56” valves OK or upgrade to 1.94/1.60” if budget allows
TTI Headers a must with good 2 1/2” dual exhaust w/H or X pipe through
Dynomax Super Turbos or Flowmasters...personal choice here
A 2500-3000rpm high stall convertor is recommended, but not necessary
for
the first stage of cam profiles but mandatory for the second choice of
cam
profiles and preferably a 3000-3500rpm convertor
Rear gears will greatly enhance any engine modifications and a minimum of
3.23 gears are requisite for any build past stock if you want to “feel”
the
value-added to your engine build; 3.23-3.91 for the first step and
3.55-4.10
for the second step recommended.
Electronic Ignition for stock and modified Poly recommended
Engine balancing and unleaded seats are “standard” in all engine builds
as
far as I am concerned.
360 Stroker Poly:
All the above with the exception of using LA low-compression truck
pistons
and fly-cutting the pistons for an intake valve relief; choice of 9 to 10
to
1 compression ratio.
Please e-mail me off-list for more information or a list of the parts
suppliers, local machine shops, and current prices I have been able to
catalog for our “PolyHeads” to make your shopping and engine building
easy.
Prices are always changing in the marketplace but I try to do a search
for
the best part at the lowest price and pass it along to our Mail List
people.
Take care,
Gary Pavlovich

Drop in a late model 360,,,,,,we all know that a poly can be built, but
the parts and availability of the later engines are unmatched,,,,,,,,
you
will end up with more HP, for less bucks,,,,,

Sleeper Build
Just doing a bit of daydreaming here... maybe you guys have some
ideas, how would you spend your money and what kind of times do you
think you'd achieve?
the car:
1963 Plymouth Belvedere 4 dr sedan, 318ci/2bbl, 727 auto, car is
totally original, e.g. 14" wheels etc. No PS, PB or air cond.
Parts budget of $2500 - $5000
some of my thoughts are...
front disc brake conversion
if possible, widen stock rear wheels and install street/drag tire
awhile back Hot Rod did a 318 budget rebuild netting 406hp for ~$1500
bucks
???
