Well, it looks like we can all agree to agree to some point. Finally, it is all relative to the amount of money at your disposal. If financial resources are of no concern, then by all means go for the gusto. If you are more like me and have to do things incrementally, I would much rather have my car run low 12s with heat soak problems, than have a 13 sec car that stays cool. I will have to address it eventually, but at least I am running with the big dawgs in the mean time.
