sorry to pick a point but boring out your engine does increase power, im not sure if its kw or tourque, but you are making your motor bigger, not much, you are increasing the cubic inch's as this usually tends to increase power does it not? mace ccan you help us out here? and yes im rebuilding a spare engine thats why im doing the boring
the acl pistons are lighter technology as well
there was one other thing i forgot about as well, i read in a post about mace doing some heads for $1200-$1500 i cant remember exactly and the details, hopefully he can fill you in
instead of pannel filter i would go pod filter (thats just preference, i dont think there would be much difference, depending on the air flow of the pannel filter compared to the pod
and roller rockeers with a cam would go nicely, if these was the same thing people would just get one or the other, the reason you probally think they do the same thing is because alot of people say that roller rockers is just a cheap version of a cam, not true, if anything the roller rockers are dearer than cams, but with a cam you have to do a lot more work to put it in, which requiers more parts (gaskets etc) which is why it is dearer and roller rockers are said to be a cheap fix instead of cam, but i would chuck the roller rockers in
mace 1 thing, you said that he would be better going 1.8.1 ratio, what about those 1.9.1 that im waiting for? wouldnt he be at more power gain with these? just wondering thats all
