4.30 Gears & T56
#7
I have 4.30's with 430rwhp/410rwtq. I think the 28"/4.56 combo works the best. I chose the 4.30's so that I could run a 26" or 27" tire because I didn't want the hassle of fitting the 28" tire. Works good, low 1.5 60ft times in a 3900# car. On street tires, it smokes them through 2nd gear at anything more than 2/3 throttle. So I definitely wouldn't want any more gear than that. Best of luck.

If you are shifting that high, I presume 7,000 is where your peak horsepower is. This is where a dyno curve is important if you have not dyno'd it yet. Why turn it that high unless you are still making power?

Seeing what it does first is definitely the best option ... the 27" with 4.30's at 7,000 rpm will be 131-136 mph depending on tire growth (if you go with a bias ply) ... !

That sounds good, but based on this thread, https://ls1tech.com/forums/conversio...rlo-ss-19.html, I would suggest working on getting it to hook before going to more gear.

Oh it hooks nasty with the Auto..cause the car is more setup for it..I've been tweaking that one here over the last week or so. Changing the setup to run for a T56 on the track will take some more work. I'm starting with the Gear/Tire combo, then working on the suspension, if I go that route.
I have the Auto setup in and ready to rock, just planning a day to go to the track and test it out with all the new stuff.

Im running 4.30s with a 28 inch tire.. wish i went with 4.56s have ms4 cam , 6th gear sucks because the cam is choppy even at 70mph in 6th and it bucks and drives me insane. i usually run in 5th because of this......
