I think you can go 120 over on a 454 but not positive.

Ari G since you arent paying attention to what anyone says. And **** you dont even type in complete thoughts. As I said before if you are buying a used motor it all depends on the block. Or you could do it right and buy a Dart big M block. Since I am guessing you have a set of pistons. I honestly dont know what the **** you are asking or even wtf you are trying to do.

im guessing hes just asking what castings are the better ones for overbore.
with minimal coreshift and such. im sure he knows hes not going to get one at the dealership parts counter.
those ***** are no help either. u have to go up there with parts numbers, or ask for exploded views of ****. they never know squat

the place i get my 6.0s
i saw some 90's duallys with efi bbc motors i think they were 454,iirc
i just go for the lsx engines. so i just glanced the bbc trucks.
but if i were to go bbc, i think my best option would be a dart block.
he should prolly just look into a dart, but i will call and see what the 454's go for.
i still think he just build up a 6.0 based motor with l92 heads

Smartmouth stop making **** up and twisting my words and acting like a child-i´ve been in sbc-lsx & import so i don´t know the perferd castings in BBC, and don´t really much care exept if i finde one in a car

What do you do for a living to be telling people you don´t know "how" to build an engine?

Anyway if you ask a simple "stupid" queston you most offen finde out who not to ask


Los:

I need a big cid engine thats the only reason why i´m using it and get the parts cheap

I got my wiseco custom FI pistons new for 100$ :mrgreen:,even cheaper then yours and THAT is a bargain

ok,thx buddy

Get it through your thick head, most 454's are the same from 70's to 1990 no matter what they were installed in.
I even got one out of a big *** generator, said hi perf pass on the block.
You're asking questions, I'm answering. What the **** else do you want.
How old are you and what do you do for a living?


What is your problem,i just asked a simple queston about castings how big you can go and head casting thats all!!!! **** off and bother sombody else with your smart mouthing
