I'm just saying for the money and time it's going to take to use an SC reliably, you can pick almost any other motor you want in there.
If it were me look'in at the money, it be a 1.8L TDI 4cyl turbo. I just missed a great deal on one.
You can find 5 cyl diesels from Mercs in the cars for under $2000. 289s in the stangs are dirt cheap. My buddies Mustang is fast as hell, he has less than $5k in the whole car.
Ask Spdrcer34 how much he spent on his SC.
