Those intakes that do have the feature only tie the rear of the heads together. They have no provision to flow water from the back of the heads up to the thermostat.
I did not tie the rear of the heads together since I did not think that there was any advantage in doing so. Tying the back to the front made much more sense to me.

I've done the latter and noticed I can run a bit higher advance (about 5 degrees) with this installed. never head of just tying the two sides together.

With the 302 in my Ranchero I had a temp gauge at both ends of the driver's side cylinder head. The temp of the coolant at the rear of the head was consistently 15*-25* warmer than the front of the head.
All the cross over can do is make the temp. difference the same for both heads. There is no way that it can increase cooling to that end of the cylinder head.
I then added tubes to the intake that joined the front and rear water ports of the heads. The difference dropped to under 10* and the engine become less inclined to ping under any condition.

as far as flow. a clean good flowing radiator (I do like the Ron Davis one that I have- And I beleave are being sold by some of the major Bronco houses)
Also a high volume waterpump and a GOOD Radiator cap. The easiest bang for the $ is a good Radiator cap.

Doesn't matter. All that rear cross-over CAN do is equalize the temps and coolant pressure btwn the cylinder heads. They do NOTHING for aiding in coolant flow.

Best thing one can do to cool a 351w is have that back crossover open. some aftermarket intakes have it open, some just have the places for drilling and tapping it and installing a crossover hose.

Spend a lot of time at 180MPH, do you? There's not much in 'ass-car that is relevant to a 4x4, or anything else, for that matter.
Seriously though, as much frontal area as you can manage is a good thing. too thick, and you are not as efficient, but frontal area will always be a help if you sacrifice nothing else to gain it.
Even more important, optimize your fan and shroud, and coolant flow. 351's are said to have an issue at the back of the heads? not sure, as I've never dealt with it first hand, but there is a cure (someone else who has dealt with this feel free to expand on this)

Hello All,
Does anyone know what the dimensions the radiators most NASCAR teams are running? I am curious because (while I could care less about an aluminum/copper radiator debate) I am looking to put even more cooling into my truck due to the fact that I have a 351 versus the 302. With the 302/5.0 there was never a cooling issue in the slightest like most people that run one. After the 351/5.8 there are times that I wish I had more cooling surface especially out here in the Southwest desert climate. What I am looking into are the 27 1/2" or 31" universal units that you find the "roundy-round" guys use.
Thanks,
Matt
