[QUOTE="Darthcobra, post: 16289007, member: 196232"] Hello I just traded for a 98 cobra with an MMR 900 block forged etc. vortech v2 big fuel etc. Well I was changing the plugs before the tune I had lined up and one plug looked awful and was pushed in the tip of the ceramic. So I knew there was an issue. Rented a borescope and confirmed my fear. It has built cobra t56 built rear end good clutch. I’m stuck now on whether or not I should swap a 5.3 ford racing engine in it with the gt500 heads on it I have now. Or should I look at the MMR 1000hp stoker? That may be more boost friendly. Should I try to salvage the mmr setup? I think it may be more money and time invested than just getting a new motor. Cylinders would need to be honed or bored. Not sure how much I can get for a cobra with a blown motor. Or if it is worth swapping engines and getting running right enjoying it then listing it for more. I figure it will be about 8k to get everything the motor clean up the heads etc. I would shoot for 750-800hp. How much is a cobra worth at that point? I want to give it a go TBH with the engine swap but don’t want to sink the cash in it and be out further than I m already. If I could figure out how to attach pictures I would to show the spark plug and the piston image from the birescope [/QUOTE]
