Big block radiator vs. small block radiator?

[Cope]

I'm building a 512 stroker for my 71 dart.

Right now I'm running the old 318 and my radiator is garbage. I'm wondering if I can buy a new aluminum rad and use it now on the 318 yet still hive it be the right radiator for the big stroker?
I'm not looking at the motor but seem to remember the H2o outlet is on the other side on the BB?

You are correct.

You can get a water pump housing to come out either side
As I built the 540 other things got in the way
I ended up using a housing with the inlet on the passengers side
26" Radiator was for a small block, with AC, out of a Fury

Good to know. Any radiator recommendations for cooling the stroker?

I fully expect to be cutting and fitting, the bigger the beter...

Griffen cross flow is a good one

Be Cool Mopar A body 1,000 HP unit. Bolt in deal. If you want to trim the radiator support you can. You don't have to.
