which oil pump (sealed power or melling)

hopefully you guys here on FABO can help me, making a decision on the new oil pump...

im struggling between

Melling M72HV
and
Sealed Power SLP224-4166V

both cost nearly the same here in Germany... the question will be, what type will be more usefull for my needs

im running a high compr. 12:1 318 relocated double oil filter (way up on the right fender) and just will add an external oil cooler in front of the radiator and also an bigger oil pan (approx. 8-9 qrt.)

oil: currently 15W40 but will change to 10W60 when installing pump and cooler

i´m adding the bigger pan and the cooler, coz. i´m fighting against higt oil temp. (about 240 up to 270 F when giving full throttle)

the question is, which one will be better, when thinking about the long route from the engine to the filter, from the filter to the cooler and way back from the cooler to the engine

waiting for your suggestions

thanks from Germany
Timo
