What's the difference between the j360 and the L 360? My vin is a L Just wondering what makes it high performance
J - 360 1 - 4BBL 8 cylinder "LA" engine
K - 360 1 - 2BBL 8 cylinder "LA" engine
L - 360 1 - 4BBL 8 cylinder "LA" engine (high performance)
The new for 1974 "E58" 360 engine produced 245 bhp (183 kW) by utilizing the camshaft, heads, intake manifold, carburetor, and dual-exhaust set up from the past 340. i got this from engine. Plymouth Duster - Wikipedia
some people say they are some people say they're not. I went to a lot of mopar shows Last Summer and every 360 duster I've seen was either not original or was a 74 so I have no way of knowing
