has any one put a new 572 big block in a 69 with factory air??

I haven't but what's the underlying reason fo rthe question?

Do you want to know if it will fit with AC?

im putting a 572 in my z28adding factory air as well, looking for someone that may have the same application

i imagin it would fit cuz a 572 isnt physically bigger than any other big block is it? and if im not mistaken bowtieguy has a bigblock in his car with all the heat and stuff it in..but his is 2nd gen.. i dont think it wouldnt be too much diffrent tho

The 572 is based on the tall version of the big block, so it's going to be somewhat taller and wider than a regular 454. Whether it will fit with the factory AC, I have no idea.

I know its taller and wider, thats my concern, guess im the first, if thats possible, hoping to hear from someone thats been there, joe

Ummm, isn't the 572 built out of a 454 block, or are you talking about an aftermarket built block for your application?
