Heads Cam Combo
I suppose he could have said that in regards to the iron head indecision and that shouldn't require research or thinking. The head porter and the Internet told him the same thing. If this is the case then I fully retract.
This is why quoting helps on message boards. So you know who and at what comment they are responding to...

Although I must admit, I am a little puzzled because the coolant is in the valley. Is it possible for it to get into a combustion chamber and sneak through an intake valve and into the valley?
Also When I put the 93 lt1 in my car is there anything else I need to switch to run my computer besides my intake, cam, and knock sensor?

to run the 93 in your car, you will have to pull the timing cover and put the original timing cover (with crank sensor), crank reluctor, crank hub, opti, throttle body, and if you choose to the intake. You will also have to move the oil pressure sending unit to the top of the engine where it is originally located on the 97, and you will have to swap the 97 injectors in if you decide to reuse the 93 intake. That's about the extent of the differences between the engines. Oh, yeah you need to put the 97 cam into the 93 engine as it has a different drive system for the opti and the 93 cam will not be able to drive the later model opti.

I was going to use my cam, opti and intake with the 30# injectors because thats what my computer is tuned for. Relocating the oil sending unity shouldnt be too hard. My question is What is the difference between the crank hub, and the reluctor. Also what do you mean by the original timing cover? The original timing cover to the 93 or the 97?
Btw. the 93 motor is complete, just has a shitty opti, so I was going to swap the opti and cam anyways.

Verdad Gallardo you need to use the 97 timing cover, crank reluctor (the 93 doesn't have one because of the OBDI) and the crank hub as it's shorter due to the crank reluctor. While you're at it, you may as well pull the crank gear for the timing set as the keyway on the 97 is a little bit longer to accommodate the crank reluctor as well. Unfortunately the swap from the 93 to the 97 is not the least labor intensive of LTx swaps.
