Engine temp issues.

[Dominator Scott]

Well guys,as all of you know I pulled my Torker460 intake and Holley 800 carb and replaced it with a Weiand tunnel ram and dual Holley 600's. The one thing I noticed right away is the fact that the engine runs about 40 degrees warmer with the tunnel ram on it.
On the Torker460 intake it has 2 threaded holes in the front for water passage. One was used for the T-fitting to the headers and the other for the dump line and a block-off plate on the thermostat housing. The tunnel ram only has 1 threaded hole which is where the T-fitting is plumbed and my dump line is plumbed into a traditional 2 nipple thermostat housing.(One for the dump line and the other is used for the temp sending unit.
Before the tunnel ram the motor ran at 140-150 degrees at idle. Now it runs at 180 degrees at idle and gets up to this temp much faster than ever before.
Here is a before and after pics for reference.
What would be the cause of this and is it something I should be concerned with?:confused:

No idea's? Not even an educated guess?:confused:

Is it possible that your temp sensor location where its mounted is getting a different reading than before? I dont see how you can get different temp just from an intake change unless you plumbing changed the water flow through the engine.

Does it get any higher than 180? if not i wouldnt worry about it!

It will climb to 190-195 after I bring it to an idle from romping the snot out of it. But the moment I come off idle to about 1500RPM's it will cool right back down to about 170-180 range and be fine.
I wondered about the t-stat housing maybe causing the temp sender to give a false reading.
