Why are 318's low HP and torque?

This thread needs to be Sticky'd because the topic comes up every month or so...when the other one finally dies.....

:happy1:

Find a 87,88, Chrysler Fifth Avenue in the junkyard....or classifieds....or someones yard on flat tires.....

Offer em no more than $400 for the car/engine....and you would have your hands on a Roller Cam LA 318, with 302 casting cylinder heads.

Or you can get one out of a truck line 87,88,89,90,91,92 D150, B150, Ramcharger....but at that point you realize there is an even better Roller Cam LA block out there available these days.

88 was 25 years ago folks.
The dodge and chrysler Roller Cam LA SB equipped family is finally starting to show up in the yards after long dependable service.

And the engine to really look for is the 88-91 Roller Cam 360.
Only produced in the Truck Line, and ONLY in the Ramcharger 4x4, D250 2/4wd, and the B250.
But they are out there....and I am finding more and more everyday....so I recommend you do the same.

4" Bore x 3.58 stroke....opposed to the 318/340 stroke of 3.31
Steel Timing Gear Set...instead of the 100% only 318 nylon gear set
HD Oil Pump
Roller Camshaft
308 casting cylinder heads with OE 1.88/1.60 valves and Unleaded valve seats...plug the smog ports and their good to go.

Those 360's are the cats meow.....:prayer: in stock form....In MY Opinion.

A 408 stroker based on one of those could get pretty radical NATURALLY ASPIRATED.

I am building one myself....and have some serious plans for the whole car....if it will ever get PAINT on it....,
MY Roller Cam 360 is shooting for WICKED :twisted: on 20 psi Forced Induction.
and I hope to see 600+ at the wheels in Race Tune.

The sky and your pocket book are the limit.
