I have some numbers for you to chew on.
The 420a standard bore is 3.445in.
The 4g63 standard bore is 3.350in:
.020 over bore 3.370 in;
.040 over bore 3.390 in;
.060 over bore 3.410 in (still .035in smaller than a stock 420a bore).
The 4g63 would have to over bore .095 in to match the bore of the 420a. As we all know, bigger bores make more power easier.
I hope this can be edited and stickied so this site can see facts instead of nooblets bullcrap.

$4.50 a gallon gas will soon more than compensate for not being able to accelerate as quickly.
