Hey folks, I'm putting together a 67 impala with a friend of mine. We just put a 454 out of a 73 chevy truck in it:cool:. Its in and running but the radiator has a few leaks. We had it inspected and they said we need a new one. Almost $400 for one from them. I found 1 on ebay that we are gonna try.

Has anyone tried radiators from here?

Any input on the radiator would be greatly appreciated:D

I will let everyone know if they are any good.
Thanks

Neil I hope your friend knows about Team Impala, if not get him to join. The radiator on a B-body is taller and wider than that used on the smaller cars even though it has the same engine. the reason being it has more frontal area to work with and the radiators on Novas and Camaro, and even Chevelles are too small which is why we have cooling problems that Pick-ups and big cars do not.

If he buys a "Generic" one size fits all Chevy radiator it will usually have a Corvette style lower radiator hose (it exits at 45° towards the drivers side instead of being straight). You have to either add in another 45° elbow made of aluminum or buy a Corvette lower hose and splice a lengthening tube in the middle to get it to reach the water pump (or your other alternative is to use a flex hose; which I refuse to do).

BeCool and Griffin and several other less well know companies will manufacture an aluminum radiator to fit the car based upon the core dimensions. Aluminum radiators generally have two cores (Howe and other racing radiators use four) which are made of either one inch or an inch and a quarter diameter tubes smashed down into an oval to increase surface area while minimizing wind resistance. Do not run a higher pressure cap unless you have removed the heater core (which I will wager leaks just as much as your radiator does now with the water running out the weep hole found behind the passenger front tire). You can run 24 psi with an aluminum radiator instead of the 16 pounds used in copper radiators to raise your boiling point to reduce the possibility of detonation. That assumes you are not running a heater which is not likely in Ohio, or you buy a custom aluminum core heater.

The chief complaints people have with an aluminum radiator is they look like an aluminum radiator with slab sided construction. Griffin is the only exception that I know of to this manufacturing rule. Griffin uses custom dies to stamp out end tanks that are then epoxied onto the core (same way as the factory does it). Once died black with a special lacquer based paint it then looks like a stock radiator without the word "Harrison" stamped into the end.

I just got one of these in for my 63. I'm going to put mine in next week I hope.It looks like a first class piece. The lower hose outlet comes straight out .I'll have to wait until next summer to see if it corrects my over heating problems.They are great to deal with and let you know as soon as it's shipped and what the tracking number is.
