Good idea deff doin that on the new ones

Actually it kinda is! Before the 4-blade prop change I was way under powered with 1600lbs and a small prop (I dont like the way that sounds,lol). So I remembered a drag racing trick we use to do on the street was Cool-Cans (CARB ONLY). You have 15' of copper tubing circling around in a coil and in a thermos and you run the gas thru there with ice-water and it cools the gas and makes it more dense so you get more hp out of it. The ones you buy dont work very well so I made my own. WORKS GREAT!! It really helps as the more you drive the hotter everything gets and you can feel your hp going away, but with the cool can my lil-Nissan truck with 400sm blk/400 trans/narrowed rearend ran cool the whole time and didnt heat up. There would be frost on the front of the carb it was so cold and it helped to keep my engine running cooler too. Its a fun DIY project. Jet

I have the same issue with the manifolds getting rusted at the drains, Like Salty said, poke it out with some wire(I think I used a coathanger) and then clean the threads with a wire brush, so you can get the plugs back in-I have not seen any rust in the block when draining it though. I am shopping for new manifolds this year. I saw some at Eddie Marine that were very nice, but I may still go stock.
