4g63 block and 4g64 block mixup

[canucatchdis]

Ok is there an advantage to using the 4g64 block over using a 4g63 block bored .020 over and putting the 4g64 crank in there? Also on a side note if i use my 90 head with the 4g63 block (with the 4g64 crank) i dont need to use 4g64 timing gears do i? If i am not mistake the 4g64 timing gears are only needed with the 4g64 block but hey thats why i am asking.

COME ON MAN there is a 23094823094092384098 threads on this. Boring 4g63 will takeing way from the cylinder walls but youll prolly be fine but the rod ratio is like 1.5 something which is suppost to suck (even tho hondas and many other engines have the same ratio). But for real dude do a search there are a thousands threads about it in way more detail. Seach the g6cs too its like the 4g64 but suppost to be better.
