In the past, I have used a 3 core out of a chevy truck with no problems. I used a four blade fixed blad fan off of a straight 6, and a plastic shroud.

This year, through some trading and engine swaps, I have four core out of a chevy truck. If you can find one great, but if not, a 3 core should do fine.

I have a 4 core out of a Caddy.It will not fit in stock location but will fit in front of the frame horn "turn outs" E bay had some of these on there new without t stat hole.For $100.If you are looking in the alum racing ones Speedway has a good price on them right now there Tru Cool series.I would get the biggest one that will fit in the frame rails were you are planning to put it.

Boz, we use a 19x26 two core Howe radiator. It works great and is liteweight. Only bad thing is they are $189. I can make an adjustable lower radiator mount for you if you need one of those.
