stock block can only be bored at most 20over. so there is no way you can bore it to 4 liter. you would need to stroke it to get that kind of numbers

boring makes the cylinder diameter larger, and stroking makes the piston stroke longer...both options increase displacement, since displacement = volume of cylinder (Area*Length)

As long as you stroke it in the privacy of your own home, you should be fine.


PS: supposedly it can cause blindness, but I've never seen any proof of this.

has anyone ported and polished your heads yet? Any inprovement in HP? I know they offer pp heads but cost way to much! Much cheaper to get them done at a shop.

the sleeves arent thick enough to safely remove that much material. 20 over would give you like 3-4 more cubic inches (think 3.55l at most) so the only way to up the displ is with a longer stroke

I recommend getting your head polished the same time you're getting stroked for full effect. Believe it or not, female mechanics tend to be best at this skill. But you'll also want to get sleeved for protection. Also, the sleeve can reduce sensitivity to premature detonation.

i usually start by caressing the block tenderly. ...but maybe just a nip of octane booster first, just to get everyone in the mood. then break the whole thing down; slap some axel grease in... and work the shaft hard and heavy. she should be about up to speed then. just make sure you take your time and have patience not to finish until the job is done.
