Take it home, tear it apart, install whatever gear you wish, do the pig swap over the weekend, then put your original pig on craigslist and recoup your $300/$350.

For anyone intersted, here is a link to the hot rod article I built my motor around. I did pretty much everything they did except my heads are different.

Small-Block Chevy Build - We Increase The Cheap 350's Grunt To 420 HP - Hot Rod Magazine

Also...here is a link to an article that did a comparison of several different cheapo heads. Mine are in there and are the floo-tek's. Might be useful to other folks.

Any shop that charges more just because he see's a Vette badge is a BS shop. The Vette diff is not any more difficult that any other diff but the gear sets are a little costly. Once you have the diff on the bench the labor should be reasonable.

If that 1200 includes: Posi.. gears.. complete O/H kit and bench labor..Its a little high. If a posi was not included than it's too high.

If you wanna try it yourself get ya some parts and we can walk you thru it.

ssmonty - I have toyed with the idea of OD tranny. I have really been reluctant to change gears because of the higher highway rpm. Not sure I want to do that, but I realize it's a tradeoff and without it I have what I have!

The motor sounds really really good right now. I honestly don't really care about the sound, just want some good off the line power.

So...I have read many a thread on here that gears are by far best bang for the buck. I am just curious how much it would really help. It will turn the tires from a stop as is (P295/50R15s)...you have to floor it and it will spin probably 20 feet. I started out on this journey just wanting some neck snapping take off. It takes off pretty well, but I was expecting much more. I am assuming it has to be my gears.

Do you think it is worth changing cams? Will I really notice that much seat of the pants feel between what I have and the 268 off the line?
I have less motor then you, stock converter, and 411's.....29" tall tire, and from a roll can destroy them as long as you keep your foot in it. Yah, on the highway I cruise at 3000rpm, but its so worth it lol. I recently hurt my TH350 so will likely build a 200r4 with a 3500 converter in the spring and get the best of all worlds.....

New rear done by a good shop is 3k more at time of sale. So that is where my advice is coming from.
I have 200K race cars dropped off at my shop and they get treated exactly the same as a guy with a rusted out Camaro. Both car's get the same quality work and both customers are treated with respect. As far as gear work... There is NO way I could spend 3K for diff work on that car. Way out of hand..

If the OP has some mechanical knowledge and some patience he can do it and try and save some money.
