Hello, i have been trying to find a radiator and shroud for the 454 for my '86 K20. I haven't had any luck finding a combo. I do have a salvage yard with a radiator and shroud, and anything else under the hood of a '90 1 ton.

I haven't been able to verify or not, whether this would work in my '86.

Let me know if you know this would or would not work. Currently have no radiator, no shroud, nothing. THANKS

What body style is the '90? Is it square or the newer GMT400 body style?

If the '90 is a square body the parts will interchange assuming they are of adequate size for your needs (350 vs 454, etc).

If it's a GMT400 then it's very unlikely the parts will fit.

Thank you. Exactly the advice I was hoping for.
