It does not matter mate, it will be awesome when finished. You never get back what you put in with modified cars anyway.
Im glad you have now realised that its definately a problem that requires a strip down, Its happened to me in the past and ive always wanted to not beleive the people telling me and thats why i didnt say anything earlier.
Dont buy another engine rebuild youres, you have caught it early so wont be too much damage, they are awesome cars, just get with one reputable tuner and stick with him, Rob is awesome but i stilll like ron and would always recommend him, then id get rob to map it.
Good luck mate its a long and often expensive road...
when you get power hungry with these though its mega!!!
