Stock 360 block and heads, 74 vintage, 50k miles, came out of mini motorhome, or at least that's what I was told. I went through the shortblock, all bearing clearances are good, put in a new high volume oil pump, has 80 psi cold, and 35 hot idling, 70 psi under full throttle acceleration, Melling cam, .444/.466 int/exh, 288/298 duration @.050, installed straight up, new double roller chain, currently has a borrowed 4 bbl cast iron intake, I finally got my Wieand action plus from Montana last week after 20 months stuck in covid jail but have not installed it yet. Trans is a 727 with unknown convertor, rear end is 8.25 sure grip with 4.10 gears. I have TTi step headers, 2.5 inch exhaust with Flowmaster 40s dumping at the diff. I have never used MSD components before this, but I have also tried running the OE Mopar ignition system too.
