4.30s or 4.56s?
I am going to ad h/c to my car but want to go bolt-on first. I am actually thinking of doing the 12-bolt as my first mod! I will do a SPEC S3 clutch and chromemoly driveshaft as well? Who makes the best d/s? AMS ok?
-Is this a good idea?
-I know 4.10's are streetable. How streetable are 4.30's and 4.56's?
-How much gain in the 1/4 will I make with the 4.30's over the 3.42's? With 4.56's?
-Will 450rwhp and 4.30's/4.56's spin on et streets? What rpm should I dump at? What size slick should I get, 26 or 28"?
-Someone, I think Verbs, said he was going to et drags from streets with 4.30's and was planning on picking up .2. I thought slicks were better than DR's?
Just trying to get a feel for drag racing?
-If my car runs a 13.0 at 107 mph with 3.42's and street tires... how much will it pick up with slicks and skinnies (if the clutch, d/s and rear held) with 3.42's?
-What about slicks, skinnies and 4.30's? 4.56's?
I am going to do headers and the intake last, after the heads and cam because that is when they really seem to shine. There seems to be almost no gain with them with a stock engine. I am going to be adding a FTRA as well. .15 -.2 realistic? Thanks for any help- Mike W.

Re: 4.30s or 4.56s?
Almost forgot, will I hook on the street with 4.30's and 315 nitto drags on a 17x11 rim? What about at a 10-20mph roll? I am getting rid of my ZO6's since they are WAY too heavy and they dont make a 315/30 drag for an 18 inch rim. Thanks again.

Re: 4.30s or 4.56s?
well, i have 4.56's in my daily driver. they are actually more streetable than you think. i drive around in od(auto) almost everywhere i go. with those gears, it doesnt take much to move the car at all. i didnt have any traction issues at all. the only thing spinning was the tires on the rims <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . but im running 27" qtp's at 11-12 psi at the track. if you have the room for 4.56's, they are fun. but thats something you need to figure out. my cam makes power all the way to 7 g's so im safe and i cross the traps at 65-6600 rpm's in third trapping at 114 with just a cam(and ussual bolt ons). good luck with your decision
