I'm trying to blast on anybodys stuff either.. instead of counting how many times you said "if" or "needed" and totally for discussion... I think it would be agreed that if you have more to lose and your conscious of it that you would take more precautions.. also if you had an unrealistic view of your self-control (which I don't) it would be easy to take less precautions... I could see one of these basic kits and a low budget or junkyard motor and going for it being a suitable match.. on the other hand someone with a little bit of coin into their engine might consider a few extra precautions?...
