Personally, If i was to build a mostly stock 360, I would put amc 343 flat tops in it with a melling MTA-1 cam, or the performer cam, both are very similar grinds if not the same... anyway, back to the specs...
4.08 bore plus 0.010 overbore
5.875" rod length
with the performer or melling cam, intake closes 27 degrees ABDC...
343 4 barrel pistons are 4.0cc flat top
343 2 barrel pistons are 12cc flat tops (so it seems)
stock, low comp 360 pistons are 28cc
Heads (Im assuming 1974+ are 58cc heads)
static compression ratios are 10.82:1 with the 4 barrel 343 pistons and 9.87:1 with the 343 2 barrel pistons...
Dynamic compression is where its at... With the melling/performer cam, the dynamic ratios are 10.42:1 with the 4 barrel 343 pistons, and 9.46:1 with the 2 barrel pistons.
9.46:1 can run on regular pump gas just fine, the 10.42 may need mid grade... My stroker was 11.6:1 static, 10.2:1 dynamic and i could run it on regular, but I lived at 5000-7000 ft... For just a daily driver, I would recommend the 4 barrel 343 pistons.
As for other upgrades... Run some nice long tube headers... the Motorcraft distributor is ok but do the TFI upgrade or run an HEI... And put on a performer intake and 4 barrel carb. Get rid of all the emissions, your motor will thank you. The motorcraft 2b is decent, but an edelbrock or holly 4 barrel, 500-600 cfm will really wake it up especially with headers and higher compression.
