    one option i have seen is copper tubing. find some existing radiator hose that is the right size, find some copper tube that is going to fit SNUG inside the radiator hose and some C clamps. for bends you can use fittings and sweat the tubes together, or you can use more flexible radiator hose and cut it up.clamp it as needed.

    another way i have seen is to find some large diameter hydraulic hose and use it. more flexible, but less flexible than you think. thick walled rubber hose doesnt like to bend to well and may even need some copper tube fittings to make the bends you may need.

    Beck at ORD used this method if i remember right.

    radiator in the rear

    thanks for the reply i like the idea of the copper tubing with flex hose joints. what about the pump ? will i need an extra capacity pump ? does the radiator have to be higher or lower than the highest point of flow in the motor ? thought i heard that before somewhere , apperently it discoureges air pockets when filling or somthing . anyway if anybody has more info for me i would really appreciate it thanks !!!! ;)

    i used copper tubing for reducers, short sections 1 1/4" to 1 1/2". use 1 1/2" for 1 1/2" hose. for the 454 im pretty sure its 1 1/2". also the copper will disapate heat when run to the radiator (especially long sections of it so that should help with cooling. id only run a few flex joints. the less joints/ clamps the better

    id run the lines on the frame and keep the top of the radiaitor above the water pump. i just used aboot 2 -8" sections of copper. short section of 1 1/" then 1 1/4"-1 1/2" reducer than 1 1/2" section sautered together.

    I'm not sure how they ran the coolant from the engine to the radiator on the DeTomaso Panteras, but stainless steel pipe could be a good (but not too cheap) way to span most of your front-to-rear distance with a pretty tough and corrosion resistant conduit. The installation would determine where to put "S" hoses as strain and heat expansion/contraction relievers and other short hose sections to point the coolant where it had to go. If 304 stainless exhaust tubing would work, it's less than 10 bucks a foot for 2-inch 16 ga (0.065 wall) tube, and I'd like 304 a lot better than copper. Galvanic potential issues might make something like a few Caddy Northstar "pills" a decent idea, but this is all back of the napkin rambling on my part.

    Are you going to try getting direct airflow when the vehicle is moving, or do you want to do all of that with electric fans?

    northstar pills ?

    i assume the galvonic potential you are speaking of is because of the water being exsposed to the pipe then running thru the motor which is a completely different metal ? also what are northstar pills ? something that neutralizes this effect ? for the cooling i am going to rely on electric fans and have a seperate cooler for the tranny also with fans. :o

    ... also, radiator cap should be the highest point in the cooling system or you'll have trouble getting it completely filled up!
