Re: 66 c10 engine upgrades
 

It seems that many of the inliners with headers and an aluminum manifold have hot engine water plumbed thru the floor of the plenum. I would think that to be a big help in a cold climate for a modified six. You can see some like that in this thread https://67-72chevytrucks.com/vboard/...d.php?t=276823 post #108 shows it clearly. And post #124 seems to have a water heated spacer under the carb.
Edit: I wouldn't hesitate to buy a Summit branded part. I imagine they'd have your back if it was detective.

[QUOTE=Chevy nutcase;9135634]My 66 c10 with its bone stock 250 runs fine but I think I can get more out of it. One thing I'd like to upgrade is the points ignition. I was wondering if a pertronix kit to replace my distributors guts is a good option or if just switching to a modern HEI distributor is the preferred method. Another component in question is the carb. Again it works fine but takes forever to warm up so I was considering a new carb and offy intake but again this is foreign territory to me as for what cfm the motor can handle. Love to hear your opinions on the matter[/Q Hello ,Ive got a 65 with a 230 in it i love the motor but couldnt get out of its own way.First i would do hei over pertonix ive used both and prefer the hei ( big difference in start up , mpg) second 0ffenhauser intake or clifford which i run and a holley 390.If you plan to bolt on headers go with the clifford,10 degreees intial timing and 28 advance and you will have a great running truck

the offy runs off of factory heat plate ive got my clifford hot water plummed and wouldnt think about not using it,the thing with inliners they tend to run richer in the number 1 and 6 cylinders the heat helps with the fuel atomization
