Just getting some input. I've got a '77 M880 (W200 Power Wagon) with a 318, 727/NP203 (full time 4wd) and 4.10s on 33" tires. The engine is original, under 100k miles, but a bit of idle time after belonging to a narcotics task force. For now I'm doing some maintenance and running the engine with some upgrades: 625 Carter AFB Wiend Stealth dual plane MSD Streetfire, Pertronix distributor, wires 1-5/8" block huggers What I'm thinking of is what I want to do long term. Being a truck I'm looking for torque, and an RPM range to go with the tires and gearing. In the future it may get a 518 to knock the highway RPMs down...but even that will still turn 2k+ at 65mph. Yeah, I know...do a 360....but I also might have access to a NIB Mopar 3.58" stroker crank (ironically one I sold, but my friend never used). I'm thinking do that with the right cam and moderate compression, revalve and port the heads. Thoughts? Cam and compression ideas?
