I have a MEL 430 in my daddy's 57 Tbird (photos to follow) and this was recently rebuilt by the local hot rod shop.
I am pulling my hair out as this baby has a problem that restricts me from driving her further than a few miles from my house. The oil temp creeps up fairly quickly and this scares me real bad.
Here is some info to go on:
diving water temp: 180
oil temp: 250 to 270 (

oil pressure: 50 psi
good fuel pressure
I live in San Diego so it the weather is pretty perfect year round. I have a thought that the problem could be the intake manifold gaskets restricting the cooling water flow. When I look at the heads, I think that the IM gaskets need to be modified to allow more water flow thru them.
In talking to the rebuilder, they are somewhat stumped but are happy to pull the engine (again) to further troubleshoot. As the MEL has some special characteristics, i am hoping that this community can steer me in the right direction and save me some $$ at the same time.
As for the photos, i have a ton but am not sure how best to get them to this board for your enjoyment. Any guidence would be greatly appreciated.
Thanks in advance,
Pinermel (yes, my name is Mel, as was my fathers, a fun coincidence)
