I am not sure if champion would be building these radiators on an individual basis or having stock readily available.
If each radiator is custom ordered then things that would need to be specified could include:
-curved or straight neck
-inlet outlet diameters. I know I have seen aftermarket radiators that have a neck down outlet that could be cut back for use on applications with a larger hose.
-overflow nipple orientation for a v8 ( on a v6 or 4cyl this is a non issue) clearance issue with pulley on v8's with ac compressor or alternator pulley on non ac cars. More correctly the important thing is where the overflow tank is mounted (passenger or drivers side as hose will loop in front of radiator if nipple faces opposite direction of where coolant recovery tank is located).
-core thickness 4cyl, v6, v8, higher hp v8. I am including a link to the griffin radiator options on v8monza.com. champion can interpret the core thicknesses etc, as they see fit.
-bung for coolant level should be included.
-bung for drain should be located exactly as original so it is accessible through hole in core support
If the overall width is close to stock, will the fabricated end tanks have square edges that will cause interference? Can someone check the clearances around the stock radiator end tanks. should the end tanks be made \_/ v shaped to add clearance around edges of tank? I think I remember locating bumps that had to be hammered down when I used a much wider radiator (5 core) with fabricated tanks.
I am going to mention the fact that v8 cars had issues with temperature creep in low speed/stop and go traffic situations and that I believe the factory used a thinner core with wider fin spacing along with a smaller water pump pulley to increase fan speed, a heavily pitched fan blade with a thermostatic clutch to reduce parastatic losses when not needed all as a means of encouraging low speed air movement through the radiator. They know more about radiator design and I will leave it up to them to determine things like fin count and core thickness.
champion uses louvered fins on their radiators

If they are going to stock radiators they will need:
-curved neck for v8 with ps or any accessory brackets that mount on drivers side
-straight neck for v8 without accessory on drivers side, v6, (4cyl?), ls conversions
If they make a 4cyl radiator should it be the same dimensions as the v6/v8 just with a thinner core or should they build it like the factory with a narrower core?
If there is no option on nipple orientation I think it should be oriented (looking from front of car) 90 degrees to passenger side. With the nipple in this location even if the coolant recovery canister is on the drivers side the hose will have clamps attaching it to the upper radiator hold down which should prevent the hose from contacting nearby pulleys.
Any consensus on whether the difference specified in the parts catalog for v8's with sport and non sport front ends has to do with:
1)the angle of the curved neck in relation to the hoodline.
2)the orientation of the nipple with regard to coolant recovery tank location
3) wider upper portion of drivers side tank.All comments appreciated.
