Default Oil & PS coolers

So my 502 is now becoming a 509 so with the added HP can I run a separate oil cooler and PS cooler? What size will be need for both and should I use this also.
Big Block Chevy Gen 5 & 6 Thermostatically Controlled Engine Block Adapter

Any suggest are welcome as I'm just now starting to understand this boat world......

A few questions, so the cooler I have now is 3" x 20" is this to small for the 509? Second question I'm going to sell the complete MPI system, Upper & lower intake with throttle body all sensors, wiring harness, MEFI1, fuel rails with injectors, MSD distributor, VST tank, remote oil filer mount with lines, what should this be worth?

Regards

I have a 3x18” cooler on my 509 and had to put a thermostat on it as it was cooling a bit too much. My setup is very close to yours so keep us posted on how the Sniper works for you as a lot of us are curious about it.

Will do, I'm also going with the thermostat block adapter, Young Performance is going to add the 02 bung and extend the inner pipe for me to keep the 02 dry. Alex at Haxby Speed is going to help me with the tune.

Btw, there is some good power left on the table with those Victor Jr manifolds if you don’t mind taking a hour to grind them out. The ports are made small so that builders have plenty of material to match the ports on whatever heads they choose. I only bothered to match the gasket but it still really opened things up.

Why did you unbolt the motor mounts from engine instead of taking off the one bolt?😎
