Re: LS Swap: Introduction, newbie, planning...

Does the engine have 706 heads? If so, could be a set of Castech heads that were known for cracking.

Also, the '98 coolant temp sensor may move the gauge in a '72, but won't be accurate. Tried that 20 years ago on my '71 Nova, which I'm sure uses the same internal gauge parts and it didn't work.
