[QUOTE=gassersrule_196;472208]why cant you bore a 350 .080 over? seen it been there done that. just like you "cant" bore a 283 .125-.155 over been there done that to. works fine. taken proper precautions.


There is nothing alike from a 350 to a 283.Except the 283 is much,much,older and more likely to crack. If by chance you got one 283 to run without running into water,doesn't cover ALL production 350's. They just don't compare.

None of the above really is useful to check for a acceptable candidate block to be bored .080. Core shift??. Now that is rolling the dice.

have you personally built one to these specs, to be able make this assumption?

Been drag racing pretty much my whole life soon to be 65 yrs old and spent yrs working in the Dyno rm at a Chevy engine plant.Not a defense.Just pure facts.

It is interesting here that you never said anything at all about the most important precaution needed. Sonic check for wall thickness. Even at that "if" you get it bored out that big,it will leave the bore's wall so weaken,it is just a short matter of time before a issue occurs. Then to shorten that time up,to tell this O/P to install a performance cam is bad advise which given what the forum is about,I couldn't just let it go. Again,just the facts.

In my opinion,you can not,should not,generalize advise based off what is a well know proven high risk factor. I'm just doing my part here with just the facts.
