Also I have a 2.1L Kenne Bell perfect shape 1250 + shipping and pay pal fees. Link in my description. There is another link in that forum for the charger. It's in perfect shape.

BTW Beautiful Mustang.

ps good luck out at the sand box.

man, almost all the people who say use 4.10s with ANY blower on a daily driven street car have no actual experience what-so-ever in testing and trying things out. They are just repeating "here-say" and are NA bolt-on (no offense to anyone) which actually for that set up, 4.10's are actually USEFUL and an appropriate gear.


On an S/C set up-If its a more track oriented set up, with suspension to make the car hook AND a tall tire THEN 4.10's would be ok... Its deffinetly not for everybody!!! Hell, its not for most people since more than half of these set ups are DD street cars with occasional to very little track play. And most will have stock shortblocks too so they cant be revving it to the moon (6800 rpm+) without seriously risking blowing up their motors which is what you would HAVE to do with 4.10's in the 1/4 and even a highway race (you aint going past 110ish at 6k rpm, WHICH SUCKS ***!!)


3.73's IMO the best suited gear for someone who has a DD with decent tires (eg: nitto 555s), few suspension bolt-ons, and a centri set up. This is a gear if you want good low end TQ without completely blowing off the tires at WOT. You will have a decent top end mph that you can use at the track without having to worry too much about running out of gear at the end of the 1/4 (abour 125ish or so).

Also i didnt state anything with the gas mileage difference between the two gears because when you fully bolt on + have a S/C, thats not really something you should be paying attention to too much.

In my case, even 3.73's were too much... YES!!! I SAID TOO MUCH!! i had a hard time catching traction in the lower gears....1st was non existing and i was constantly fighting 2nd to get it to bite. guys thats not fun when your trying to win races, launch the car, keep straight on the road. Image 4.10 gears... hell no man. So i threw on drag radials and backed down to 3.55 gears.... IMHO thats the BEST DAMN SETUP you can have for a street car. And if you build your motor later on and up the boost so your near 500 rwhp, youll thank yourself for having a gear that can easily take you 130+ and youll automatically have great low-end seeing that you built you s/c set up right (pully it to the max so boost comes on quickly, get appropriate cams, and bolts on that will net increased low end tq eg: lt's) But hey like the 4.10 guys, this might not be for everyone either, i just like whats PRACTICAL and useful in my set up (425 rwhp, bolt ons and NO lt's)

3.55's FTMFW!!!

(my post was entirely concerning the OP chooses a centri setup, if your going to run a roots or twinscrew your *** BETTER stick with 3.55's or lower unless your car is track oriented)
