I've read quite few posts that let me know I'm not alone on a deal I stepped into, so here's the short version: I picked up a 1999 Cobra Convertible 5-SPD (Black/Black) with 75K on it and new tires for 2500. Bought it off a friend that had it since new to get it out of his barn after his son brought it home one night with a very clear knock. It starts and runs, shows normal oil pressure...but it has an issue needing dealt with that I'd describe as a knock...some would say it's more of a heavy tap.... Not certain what that issue is, or what my plan is, but bought it figuring worst case scenario (motor gone) as a possible step in my recovery process from selling my 1969 Mach 1 30 years ago to buy an S-10 for college...darn. I am mechanically inclined enough to do quite a bit but time challenged. I'd like to figure out what I'm likely dealing with to get a version of a plan working. Not building something for the track and not a daily driver, just something to bring back to life with better internals and likely working into a super charger and still able to keep the same transmission, rear end etc... Here's a video sound clip...if it helps for those who have been here before.
