I would like to get a little more performance on the street. I plan on keep the same setup as in the signature with the exception of either heads or 4.10 gears in the 10 bolt. I know everyone says that our 10 bolts are weak, but I'm thinking that I should be ok as long as I stay off the track and don't run drag radials (correct me if I'm wrong). I figure both will significantly increase my performance through all the gears, but the 4.10s will make it a little easier to drive (although it's really not an issue now) and will save me a substantial amount of money. What do you think?
Thanks,
Jim

I've seen people break 4.10 gears with street tires. If you saw how ridiculously small the pinion gear is, you'd laugh.

Thanks for the quick responses!
Which would be more susceptible to breaking, 3.42s in a 10-bolt with heads or 4.10s in a 10-bolt without heads?
Thanks,
Jim

He recommended putting as much power to the pavement as the street tires could handle (e.g., heads or gears in the 10-bolt) as opposed to hooking-up hard and damaging the body of the car. However, I do not beleive he has ever worked on an F-body, so maybe a 12-bolt and subframe connectors wouldn't be that bad ... I don't know. But that's why I did not consider installing one. Also, if I did heads I would do them myself, so the total install would be considerably cheaper than a 12-bolt (obviously that's dependant on which heads I would buy - which is a whole different topic)

I voted heads by accident. Hey, it's late....
12 bolt with 4.10s or 4.33s, sticky tires (nitto drag radials, for example) and subframe connectors. Car will be perfectly fine.
How's your clutch?

See, the thing is that not everybody can afford to throw ~$2,500 down at any given time to buy a 12 bolt because they broke the 10 bolt.
