dont fear the gear, the 4v mod motors love to rev. i have 4.10s in mine and at 80 mph on 5th im doing 3k rpms, with 4.30s its not gonna be to much higher. i actualy want to go with 4.30s if i keep my car n/a.

Yeah i talked to several different shops and they told me the difference between the 4.10 and 4.30 is minimal and i would get more bang for my buck going 4.30 since im staying n/a

That is too much gear.
4.10 is as high as I would go and I think that is too much.
Wrong answer! 4.30's or even 4.56's are the preferred choice for a N/A 4V! Do the switch!

i rather supercharge mine before i put cams in it. if i decided to keep it n/a, id take the heads off get them ported, id take the intake manifold off and get it ported and have them make the runners shorter, put stage 2 cams in it and 4.30s. run 11s or faster n/a with the right suspension setup.
