High-flow vs Standard-flow thermostat

[kerber0s]

Hey everyone.  New to the forum but super excited that I found it.  My wife just bought me a '70 sport about a month ago for birthday/Christmas present (she's a keeper).  Doing the Borgeson power steering upgrade which requires replacing the stock pulleys.  As I was putting in the new PS gearbox I discovered that there are a few holes in the radiator so I drained the coolant and pulled the radiator.  While I have the radiator out..... may as well replace the water pump and thermostat..... right?

So, stock 302 and I'm going with standard-flow water pump because I've read some posts suggesting not to use high-flow if you don't need to.  What effect would installing a high-flow vs standard-flow thermostat have?  

Thanks for the help/input and I'll update my profile later today with my rig info.

Hi Kerb.., welcome..!

Yes.., your profile helps.., especially with cooling & carb issues.  (meaning include your location as well) 

Hi-flow(s) is really meant for hi-performance (hi-rpm) engines. Your rig isn't in that catagory.

What did the coolant look like coming out..? If it was dirty.., I'd put the old radiator back in & flush the system

real good B/4 putting in a new radiator.

If the eng. was running at normal temp. at hi & low speeds....,  really no need to do the pump & 'stat. at this time.

These items are easy to get to with rad. in place in most cases. However, rad. is quick-n-easy to R&R

"Rule of thumb" is.., "if it works, don't ***** with it."  (It's your call)
