Words of wisdom, from a wisemen! I like this statement Jasson. This is so true. I thought 4.1, and 3.8 are not Bullet proof. Does not Hp to flywheel play a part on these blocks?
Yep, there is no such thing as bullet proof. The closest thing to that is stage II and they are not bullet proof either. Things breaks when you think that way.
There are allot of things to be factored in. It's not always power that breaks it. Something as stupid as a cheap oil filter can ruin your motor. Specially if your trying to push high viscosity oil through it. Something most people never think of when using them. Even though they been advised they still use the cheapest filter available. A big no no.
Finding a builder who knows what he's doing is important. Even more important is a educated end user.
tough crowd in here......
the man asked where to get a correctly built shortblock that wont kill itself....A bad tune can kill ANY engine in ANY car....a buick is nothing special.
it would have been different if he said " im looking for a bulletproof shortblock that can withstand the fact that my thumbwheel chip has the settings worn off , my Translator speaks jive and i will do ANYTHING to be the fastest car in school on 87 octane"
even a kevlar vest wont save your life if you put your legs through the holes and pull it up like panties.
