New Radiator questions/suggestions

Hello, Let me first apologize if any of these questions are well lets just say unique......

Im looking at a new radiator for my '68 and I would like a polished one as well. Possibly in 2 years or so I may be swapping engines with a bigblock...I know that there are both small and big block applications. Is it possible to get a big block radiator for my 350 just in case I decide to go that route or no? Also what brand do you guys recommend? Thanks in advance

Re: New Radiator questions/suggestions

Benito,

I have just done some research on radiators and bought one. I am far from an expert but from what I have found the big block radiator is larger than the small block. Either one should fit your car but you may have to make some modification. I went with the big block radiator for better cooling. Haven't installed it yet so I cannot say that it fits but I am not worried. Good luck with your decision.

Re: New Radiator questions/suggestions

A big block radiator will bolt right in to your car with out any problems.The core support has two sets of mounting holes for both sizes of radiator from the factory.The big block radiator has a 23'' core versus the small blocks 21'' core.You will need to get the appropriate fan shroud for your application.For your set up you will need a small block with A/C fan shroud.I have this set up in my 69 small block car and a buddy of mine has the same set up in his 67 small block car.We both went with Griffin aluminum radiators that have 23'' dual 1 1/4'' rows.The radiators bolted in perfectly.I am not sure if they offer a polished version,I hit mine with some of Eastwoods radiator black and it looks dead stock.An aluminum radiator with a 23'' core and 1 1/4'' rows will handle a big block no problem when you are ready to make the change.

Alumitech is what I finally bought. I live in the south and the big block radiator with the single 16" Spal fan works perfect. I never even make it to 200 degrees anymore. It is worth the extra money trust me.

Re: New Radiator questions/suggestions

The reason for the mentioning of the A/C fan shroud is because it will properly fit the 23'' radiator.Standard non A/C small block cars used a 21'' radiator and in turn a different fan shroud to fit that radiator.Small block A/C cars and all big block cars used the larger 23'' radiator.The big block fan shroud has the opening for the fan offset to the passenger side due to the factory offset of the motor to gain clearance from the steering box.The small block version has the fan opening more towards the center of the shroud because there is no offset in the small block set up.The 23'' big block fan shroud is also shorter than the small block shroud due to the fact that a big block is physically longer than a small block.This was changed in 1969 when all small blocks received 21'' radiators and all big blocks received 23'' radiators.The core thicknesses varied depending on the options.I hope this clarified things a bit for you.Good luck!

Re: New Radiator questions/suggestions

Benito, don't think of the 23" SB radiator in an AC sense (although use of the SB AC shroud is mandatory for your current SB application).

Think of it as a future 23" BB radiator (you'll only have to swap out the SB shroud for a BB one when the time comes).

Re: New Radiator questions/suggestions

I live in Las Vegas, NV and the Mojave Desert, which it gets extremely HOT HOT HOT here in July and August, I like to cruise the World Famous Strip at night, and hear all the comments, pictures from the Tourist. I have a 68 Camaro Coupe with a 350 and 400 Turbo, and when running the Stock 3 Row Harrison Radiator in bumper to bumper traffic, the car would heat up, and knew you had to get out of the traffic, this went on for a couple of summers, then decided to and purchased a Flex a lite Aluminum radiator with the electric Single fan and shroud, set it up for it to kick on with the thermastic control, this solved all my heating problems, I highly recommend Flex a lite at least for use here in Las Vegas and the extremely hot weather conditions. They have assortments for many collector car's, and have an excellent Customer Service Dept, that knows their product and what they recommend for your ride..........There are many radiator builders out there and they all say their's are the best, could be I don't know, all I know is my experience with the one I have in my Coupe, it works for me, and could not be more pleased.........
