I have 87 Century with an alpha one, gen one. The lower shift cable was broken, so I pulled it all and did a complete bellows, shift cable, overhaul. I guess I was poor when I ordered the bellows overhaul kit and got to looking at it and the lower water hose was branded, "Lucky Bird" or some silly name, I had a hunk of Goodyear High miler hose that looked like a better deal at the time. I picked the Goodyear. Well after it was all said and done the goodyear had too thin a wall thickness and kinked. I really did not want to pull the whole thing off again and found a stainless steel spring that fit inside the hose, that did take the kink out and the hose looks great. What I am concerend about is this: the inside diamere of the spring measured .515 inches or 1/2 inch. I didnt think too much about it due to the pipe coming out of the water pump is 1/2 inch copper, looks to be regular hard copper tube, which measures the same as the inside of the spring. So, my thinking is that the most flow possible to the engine is through a 1/2 inch I.D. tube. I know the pipe goes from 1/2, to 3/4 then to 1 1/8th inch. I restricted the 3/4 to roughly 1/2 inch. Am I going to have enough flow to the motor. If not, my plan is to go with a crank mount pump and a thru hull. (I can plumb) Actually, the crank mount pump will be easier to change the impeller, Much easier in fact, I can buy a johnson pump on ebay for about 150 bucks and a thru hull for another 50. so, about 200 bucks would fix this if flow is too low. Now, I am up to maybe I would flow too much! a full 1 1/8th plumb will provide a lot of water, I did this on a Chris I had and it worked o.k. even tho it was a full cam pump for a big block. Comments? Appreciate pro assistance.
