Lots of great suggestions
Built lots of Bus and Boat Motors so here goes
Oil cooler -detail oil system corners and the windage tray etc suggestions
road race pan
tranny cooler (100 plate and fin) no S tube type) with half inch in and out and half inch oil proof lines) (Ford truck at pick a part)
Throw some tall tires on it
If the motor is not built yet build it with some quench and keep the overlap down if stock heads use the motorhome 352 heads with the cooling holes for the exhaust valves if stock heads use the motorhome valves viton seals light dual springs bronze guides with the spiral
if roller tip rockers go to the B3 page and read the 4 tech articles
get your geometry spot on (even if the motor is already built this is an easy fix)
if stock rockers lash caps (stock rockers are not what they used to be)
and oil through the lifters (Magnum style) and pushrods for the rocker cup
I'd recommend at least Iron rockers if any spring pressure and do not like aluminum rockers for any endurance build
once broken in think 0W-40 Eurospec synthetic (MB and BMW approved made from natural gas)
earplugs or headset for your tunes

plug all holes in the core support and run a spoiler/ valance
