340
Six Barrel Engine, Transmission And
Rear End Information:
|
| The 1970 Plymouth AAR 'Cuda
featured a unique 340 small block engine. Factory rated at 290 hp,
its true horsepower was closer to 325. Just opening the hood of a
AAR 'Cuda reveals this is not your average 340 engine. For starters
Ma Mopar used a large oval shaped air cleaner to seal to the
fiberglass fresh air hood. Underneath was three Holly 2300 series 2
Barrel carburetors sitting on a painted Edelbrock aluminum six pack
intake manifold. |

| |
| The 340 Six Barrel
engine featured a stress relieved block with a high nickel content
and filled oil pan rails. Additional material was also added at the
main bearing web area to allow for 4 bolt main caps. However 2 bolt
main caps were used on the production version. |
| |
| Heads were regular J
castings with modified pushrod holes drilled offset from the ports,
this allowed the ports to be modified without breaking thru the
pushrod holes. The rocker arms were adjustable similar to ones used
on the 426 HEMI engine. Rocker arm shafts used additional banana
shaped lube spreader grooves. |
| |
| The package included
High flow cast iron exhaust manifolds with dual mufflers located in
front of the rear axle and side exiting chrome tips. A close ratio
four-speed with a Hurst pistol grip shifter was standard. The 727
torqueflite was optional with either floor or column shift.
|
| |
|
All AAR's were equipped with the 8¾
sure-grip rear end. Information from Chrysler states that the rear
axle ratios were 3:55 (Standard) or 3:91 (Optional) however
many AAR's were equipped with 3.23 gears. |
