I like the 318s many years ago I broke my 340 and has access to a bone stock 318 out of a 70 Charger that was being converted to a big block .We didn't do much except a stock 340 cam it went 14.00s in my 68 Dart with 3.91s and 10 inch converter , trans was and still to this day a 904 with a manual reverse pattern valve body. We put a fresh set of 360 heads with a good valve job and it went 13.20s the biggest change was the converter I swapped from the 10 inch to an 8 inch race converter and it went 12.60s still with 3.91 gears , I wish I had never sold that motor. I have a 318 (5.2 Magnum ) motor in my 92 Dodge short bed regular cab 4x2 original owner pickup ,the motor has never been out of the truck : it has M/P hi perf. computer , shorty headers , 3 inch single exhaust with a Flowmaster muffler , throttle body spacer , ram air system , redone lock up converter ( lowered my 60 ft. times 2/10ths : 2.20s to 2.00s ) , M/P shift kit in the 518 trans, swapped the 3.55 open rear to 4.10s with a sure grip , swap meet traction bars , Rancho B body shocks , drag radials : I just took 100 lbs out of it recently and it ran its best E.T. ever a few weeks ago 14.98 @ 88.75 mph, 2.05 60ft . Over the winter I am considering one of the Hughes modified throttle bodies in my quest to get even further in the 14s .
