cool intake

ok i have seen where getting an intake system for this truck is pretty much a waste, ive also seen where using insulating tape can do the same thing, can someone explain to me exactly how this is done, like what i tape up and what not, exactly what tape to use, and how much am i going to notice the difference, i live in orlando fl, so it is hot as hell down here, thanks guys

i have not yet done it but plan to....all i know is you wrap up the box with the reflective heat tape...i guess you could wrap up the hoses also if you wished....basically, whatever is wrapped in the tape will insulate the heat out. how much gain? i honestly couldn't tell you. let us know what you find out.

Plumbing in some cool air will help during summer months, but going to the trouble of insulating the air intake tube/ box probably isn't going to do anything. The incoming air is going to be moving fast enough that it's not going to pick up any appreciable heat, especially if your intake tube is plastic. If anything put an insulating spacer under your carb. You'd have to make one for the stock 1bbl, but if you're running an aftermarked 4bbl setup they're readily available in 1/2" and 1" heights. You get a boost in velocity from the spacer plus cooler fuel. Also doesn't hurt to insulate the metal fuel line going from the pump up and over to the carb. This would do little for performance, but helps prevent boilover in the summer.

I am rebuilding my 240 (carbed) and was thinking of ways to insulate the intake manifold, fuel line, air intake hose, and breather box. Basically I was looking into slipping header boots/sleeves over my header runners by the head and also having the outside of the intake manifold coated with a thermal reflective coating. I will probably also place a metal heat shield between the carb and the manifold assembly with a phonelac spacer between the carb and the intake manifold. Everything else--fuel line, air intake hose, and breather box--can be insulated with insulating items available from any hardware store. However, some heat in the intake system is needed to keep the fuel in the air/fuel charge in vapor form (this would include injection into intake runners as well). I don't know if this would make that much of a difference, but I'm in Mississippi, and our winter/cool weather is only a few days per year. The rest of the year is extremely toasty.
