Boring our increases displacement right? Is that something we can do with our beloved 4.6 mod motors?
Is there a way to change it from a 2v to a 3v or 4v?

Seems like with a stang all you can do is blow it, cam it, and bolt **** on. What else can we do that isnt something everyone does?
I'm not exactly sure what boring is, I do know that it does increase engine displacement, but as far as adding more valves, it's very expensive and not worth the gains you'd get.

Well I'm no expert either but boring is basically enlarging the cylinders in the block, obviously requiring larger diameter pistons. The increased size increases displacement. This was done to my v6 when the headgasket blew, like .030 over. It could probably be done to ours as well but I don't know extreme you can go. Stroking also increases displacement. There are kits out there that could increase the 281 up to I believe it is a 324, but that is the extreme. The walls start to get thin, almost dangerously thin.

we really cant bore out our mod engines too much casue each sleeve are really close to each other.......over bore it and u make the cylinder walls weak and it runs the chance of that wall breaking leading to all hell....stroke it if anything

Default Why bother?

Once.. again if you don't know what you talking about STFU!!!!!!!




Btw- a performance rebiuld is ALOT cheap and most the time better than a crate swap.

its really not necassry to bore anyway - that mostly ego talkin - forged parts and forced induction will take you as fast as you want to go.

buy an aluminum block and have darton sleeves made to bore your motor to 302 cI. its better than stroking but its much more money
