I agree, I only bought the radiator because I was too lazy to browse through the napa catalogue to find the right size heater core for my case. But its been replaced in the new setup by the Chevette heater core, and temps in the reservoir are fine, so I think its doing its job. I read through several of the older posts, the first 2 pages that came up wen I searched for "MAZE" Wouldn't let me search for Maze 2. Anyway, one of the tips jumped out, touch the cpu block and see if its warm. Well, its not warm, but it is warmer than it is when the system is off. I can feel a difference in temp on the inlet (cold) and outlet barbs (warm), but the rest of the block feels ok.
The pelt and NB block will be here tomorrow. I am definitely going to replace all of the lines in the system with 1/2" ID tubing, but I'm still not sure how much its going to help, since both blocks have 1/2" OD barbs. I GUESS the resistance caused by 4 3/8" ID barbs would be less than the several feet of 3/8" tubing, right? So I should see something of an increase in flow, even if its not much.
The only other thing I can think of is just to split the lines coming out of the pump, bring a 1/2""ID out of it to a 1/2" ID Y, then run a line to each block, and combine with a 1/2" ID just before the radiator, with a 1/2" ID return line to the radiator. That should keep everything over spec right? Or atleast minimize the resistance effect of the barbs. Does my logic work? Will it be worth the hassle, or should I just run pump-NB-CPU-Hcore-pump?
