Hi,
Long story short, I was driving my car across country (97 Cobra with an aviator swap), lost an idler pulley and limped it to a Napa auto parts. Engine got a bit hot and hasn't been the same since (runs hot). Other than that, it runs fine. I did a combustion gas test this evening and it turned yellow (should have stayed blue if HG not damaged).
Options are:
1) Pull engine, replace head gaskets, visually inspect for cracks and hope for the best. I have headers and 97 cobra cams to go in during this. I could also have some head work done, maybe mill 10 thousandths to ensure they aren't warped. How likely is it that the block or heads are warped or cracked?
2) Get a different engine. I have an in on a Navigator long block in great shape for 1K. I have a cowl hood and ported 01 cobra intake on the car now, that I could use. In parts I have an 8 bolt flywheel, shorty headers and 97 cobra cams to go in. I know there are better cams, but the ones I have looked at are ~1200. I think I could swap engines to this for a pretty reasonable cost.
In either case, I don't have the cash for a full rebulid of the current engine or a coyote swap.
I am debating which way to go. Each has its benefits, but wanted to see what you guys think. The car ran well before this happened. I beat a friend (2 of 3) with a Calloway Vette with a Lt1 383.
Thanks for taking a look and let me know what you think.
