Kirden Posted June 27, 2013 Report Share Posted June 27, 2013 I would like to get the measurements of the radiator that should have come with my truck. The 74 radiator is not the same size as the L20B equipped 620s. The goal is to find a three core aluminum radiator that will fit, or have a custom radiator made that will fit. I am building a LZ22 for a supercharged application, so I need something that will be able to cool it. If anyone knows of a radiator that will fit and has been used on a boosted 620 application, let me know. Quote Link to comment
Dawa Posted June 27, 2013 Report Share Posted June 27, 2013 youre lookin at custom manufacturing OR retrofitting. ive done this search, even contacted koyo about making em. even bought a 510 rad to make it try n work. this is from a 73 620 (L16) fsm height/width/thickness 620 13in 17.6" 1.26" Quote Link to comment
Kirden Posted June 27, 2013 Author Report Share Posted June 27, 2013 Thanks Dawa, that should be what I need. Now I'll make a mock 13x17.6x3 cardboard box and see how it fits :) Quote Link to comment
Guest_kamakazi620 Posted June 27, 2013 Report Share Posted June 27, 2013 Why not just use a 720 radiator? ? Quote Link to comment
Kirden Posted June 27, 2013 Author Report Share Posted June 27, 2013 I don't want to cut my core support at all. Does the 720 fit into the 74 without cutting the core support? Quote Link to comment
Dawa Posted June 27, 2013 Report Share Posted June 27, 2013 one thing i will say is that along with different rad sizes, the radiator core supports were designed different as well. i thought it would be as easy as cutting away some metal and drilling new holes but the sheet metal is 'punched' so it not as easy as that.

Kirden Posted June 27, 2013 Author Report Share Posted June 27, 2013 Yea, I plan on mocking something up first if I have to go custom. I do not plan on cutting my core support. Pretty firm on that, even if it means using an in line filling position. Quote Link to comment
metalmonkey47 Posted June 27, 2013 Report Share Posted June 27, 2013 Boosted LZ22? Got a block yet? My L20 block is all yours if you want it. Quote Link to comment
Kirden Posted June 27, 2013 Author Report Share Posted June 27, 2013 I thought you had already sold it so I didn't ask. That would be perfect MM. I may not be able to pick it up till Sunday though. Quote Link to comment
