Centering Griffin Performance Fit Radiator?

Hi All, getting ready to install a new Griffin radiator. To center the radiator core with the core support opening I'll need to drill some new holes in the "Dynacorn" core support about 1.5 inches toward the driver side. I'm OK with this, but if I'm going to drill new holes what is the recommendation for centering vertically, just do it? Centered, higher, lower? Am I overthinking this?

Thoughts?

Thanks!

Re: Centering Griffin Performance Fit Radiator?

There should be two sets of holes on the driver side. One set for SB and the other for BB. The BB holes are in the neighborhood of 1.5" over from the SB ones. Are you saying you need to move it 1.5" past the BB mounting holes? What are the dimensions of the radiator?

Re: Centering Griffin Performance Fit Radiator?

I've been intending to move my griffin radiator over to center it also since it kinda bugs me when I look through the grill, but I'm also going to paint it black,so you really wouldn't notice it being off center anyway.

The dimensions of the radiator core are 22.5 w x 17.5 h. Core support opening is 22.25 x 15.25.

In the pics the height is off, but you can see the alignment with the existing holes in the core support while the radiator core is centered horizontally

Re: Centering Griffin Performance Fit Radiator?

So what you are saying that with the radiator core centered in the support, picture#1 & #2 represent where brackets would be for new holes drilled, correct? As far as up and down, I would drill new holes even with the original holes in the support, just moved over where you need them. You can always check it and split the difference since 17.5 core and 15.25 opening on the support would be 5/8" if you split the difference and centered the core in the opening.

Yes -

Centering it makes sense to me, guess I don't understand why it's so far off out of the box. Just wanted to make sure I wasn't missing some piece of Camaro lore on the offset to the passenger side.

Thanks -

Re: Centering Griffin Performance Fit Radiator?

I'm probably going to install an aluminum radiator and eFans... and I have a big block so the engine is offset to the passenger side. But since I'm not gonna use a conventional fan off the water pump, I think I might just center the radiator on the core. Have to decide when I see it in place.

What fan setup are you using (diameter, CFM, brand, etc.)?

Workmanship looks great, don't know if it holds water yet -
