Dad got this back when his dart was under warranty for his 69 340, but installed another mill. It's been well preserved over the years. Going to build it to put in the dart since the old motors showing it's age. The plan is blueprint the block decks, maybe a fresh hone, and replace rings and bearings with more modern materials. Install an NoS racer brown .528" solid cam I've got. Good timing set, and a hv oil pump. Will be using a set of X heads that were built by R&J performance many years ago. Re using a few parts like the milodon 8qt pan, headman big tube huslers. Stock valve covers, air cleaner, etc. Just like the engine it's replacing. Trying to use parts I have and make it look like the motor was never changed. The car is pretty much original. Stockish suspension, 4speed and 4.88 gear. It's went 11.88 on slicks with current combo. Has a weiand X Terminator and an old Holley 780. Any suggestions on a modern single plane and carb combo that might be an improvement? Running a recurved electronic distributor and crome box for 40 years with no problems. Anyone have any suggestions on this build to keep it simple, stock looking, with a little more snort? Not looking to go stroker or aftermarket pistons. The ones we've run for 40 years never had a problem and been way past 7 grand many times. Just trying to get the most out of this old factory stuff that we all know can run and last. Car don't see much strip time anymore, but gets a good workout a few times a year. Thanks for your input
