Neck Size ?
I am in the process of ordering a BECOOL radiator kit, etc. and here is my problem / question;
The BECOOL necks are 1 3/8 on top and 1 5/8 on the bottom, and this is the outside diameter, and as far as I know standard should be 1 1/2 and 1 3/4. Now, I have ordered a Stewart water pump which has a standard 1 3/4 end and I assume my ZZ430 crate engine has a 1 1/2 water neck, so..... Does this all sound correct, does anyone have a BECOOL with no problem, do I need a sleeve for the radiator & so on. I have not measured yet, but would my stock 86 truck with A/C radiator really measure 1 3/8 and 1/5/8 from the factory, making BECOOL's setup correct. The one I am ordering is for 73-87 pickups. Maybe not a big problem, just odd to me. Doug
