Hey guys I currently need to get a new engine and gearbox for my 97 lude I had a BB6 engine and I have been looking around for a new one. I have found earlier lude engines such as a BB4 but my mechanic said it will not fit or be suitable? I am having trouble finding a bb6. What engine is a suitable fit and cost efficient? If anyone can direct me to a place where I can find one that would be appreciated also.
