thanks all, this motor is coming out to make way for a 440. It seems to be a solid build, but is overcammed and has a eddy torker intake. Like so often, someone threw a few parts together make a "race motor" LOL

it will be used as a replacement for a tired 318 in a 79 Power Wagon. I have a performer 318 intake and a 421/441- 278/288 cam that should be much better suited to be a decent driver, with the closed chamber heads on a 76 bottom end I should be somewhere around 9.2-9.7 if they havent decked the block or shaved the heads. I will cc both to get a true comp ratio, and a cursory inspection of the internals . ill follow up with pics in a few weeks as time allows.

not that this pic is helpful other than it is proof of their existence. it threw me for a loop when i pulled the plugs, and didnt see the horseshoe opening around the crossover. when the engine comes out ill post better pics for reference.

Whats the problem with that trucks frame???

that is a shadow line from the chickenscratch brakelines and a metal spring clip of some sort. but does look funky in the crappy pic

For anyone interested at least some of the 318-3 cranks were forged and years ago they were sought after by racers and those looking to weld up a stroker crank. They are HEAVY as the rod journals were not drilled. Like most things with ma mopar I can't say all of them were forged, but the few I have seen and owned definetley were forged.
