Today, dollar for dollar, is the 318 faster than the 340 ???

5.3 LS has a 3.78 bore...... and like them or hate them, enough of them have run some very fast times......


If I was to say I'm gonna put a 5.3L LS in my car other than a Chev into a Mopar no one's gonna say 5.3 are junk only use 6.0L LS, but if I said I'm going with a 318 with edelbrock heads people would be your wasting your time can't make power or it's gonna be a race only engine, even though both engine should make about the same power since similar displacement and air flow.
Aww yeah the old 2.2's

Well I did a quick internet search 400hp 318 and behold one of the mopar magazines did a 400hp 318. The recipe kb pistons, comp 280h cam and magnum heads with a mopar performance dual plane intake 400hp at 6,200. Factory crank and rods stock magnum heads. I think for that combo there are better options then the chevy 280h grind though

There been 4 different magazine builds that made 400 hp none were all that complicated basically 220 cfm heads with 10:1 275-285 cam and headers pretty much the the same parts that you would use to make a 400 hp 340/360.
