when doing a swap to a sbc you can use a 1974 chevy nova radiator it is pretty dang close to stock size but you can get them in a 2, 3, and some time 4, core whatever you prefer.

Awesome, is it hard to get it to bolt up to the stock holes or do you still need to custom fab brackets?

Thanks,

no you will have to do some custom brackets to get it to go in there but it is pretty much the same as the stock 87 radiator.
