What should I do with $400
The Best V8 Stories One Small Block at Time
I would do headers!! A cam on stock manifolds will get you next to nothing. also, a cam on the stock stall also makes it a dog off the line. Replace the valve springs if you have the money, when I replaced the ones on my caddy, It felt like I had added a cam. No longer did it drop off around 4200.
1) First off, if you spend 400 Dollars on rims, they most likely aren't high quality. If they aren't AFS or GM, dont get re-productions.
2) If its a DD, you will want Coated Headers. To purchase nice LT's like Pacesetter's is easily 400+ dollars, not including the Y-Pipe or Installation. Which could be another 2-400.
3) If its an A4, you don't want 3.90's or 4.10's.
I would go 3.73's.
If you do have 3.23's, dont worry about gears right now.
4) What Mods do you have?
A nice cold air kit is going to run around $180, unless you get it used.
A nice exhaust like Magnaflow, SLP Loudmouth or even a basic Hooker Catback is $300-$500






Just make sure the are LTs.
