It's hard enough to get a 360streeter into the 11s with the proper gears, suspension,and TC, but with 3.23s you're gonna need a lot of power.
Just to hit say 11.9, takes a p/w(power to weight ratio) of about .111 and unlimited suspension. At 3450# raceweight this is 3450 x .111=383hp. This will get you around 111mph( but not necessarily in the 11s yet.)
With a street suspension you can add about .5 second so your 383 hp car will be about a 12.4ET.
Working the charts backwards, I get a requirement of .127p/w to go 11.4 unlimited, or about 11.9 with a street suspension. This is 3450 x .127=438hp.
So the math says you need 438-383=55hp to compensate for the street suspension, In a car that goes 111mph.
And we haven't even figured out where you are currently at. And we can't.
The charts assume unlimited suspension, so trapping in second gear with 3.23s doesn't count, and there's no compensating for it. If you really want to know; 12.66 with street suspension is about .103p/w and at 3450 x .103 this is about 355hp, best guess. So for you to go 11.9 with street suspension, you would need 438-355= 83hp.
Now before you go crazy, The charts assume you have unlimited suspension. As in trapping somewhere close to the right gear. There is no way to estimate for your situation. Your average hp is just too far down using just two gears, or being so far out of the powerband in third gear.
If you want to get a better idea of the power increase required, borrow a set of gears from 4.30 to 4.88 and get a trapspeed, or at least an average of three of them. From that, the charts will spit out a much closer hp number.
But to be brutally honest,it takes a lot of power to get a street car into the 11s with 3.23s even with 3 gears. Or more accurately it takes a lotta p/w to get a streetcar into the 11s. Get the gears and then get rid of 200 pounds then you'll see what I mean. That alone might get you really close.
Of course you are now waaay out of the realm of street,for you.
So of course to get back to streeter, you would need an od trans. Enter the A500. The ratios are 2.74-1.54-1.00-.69 And I would probably give up a little ET to use 4.10s. ( cuz 4.56 x 2.74 is ridiculously low). These 4.10s will get you an 11.23 starter, and a trap rpm of 5800.
And if it was me, I'd probable swap a fast rate-275* cam into it. To bring the power peak down to say 5400. Yeah it will be a tad slower on the track, but that 275 will make a world of a difference in 95% of your driving.
And now 65=5200 at the top of second, right on the powerpeak of that 275 cam, and you can twist that 275 all the way to...... well........ 7200 if you have good heads, but the best place to shift it, if continuing, is about 6200.Which will be about 78 mph. So that sounds crazy right? 78 in second gear? Hyup.
Hyup, that tranny has some very wide ratios.
A better choice is the A518 with ratios of 2.45-1.45-1.00-.69od.Now you can run 4.30s. Or even 4.56s. Hyup.And still cruise at 65=2420(no slip), with those 4.56s.
But I only ever had one set of gears that big (4.88s) and they were not very quiet. My 4.30s however I could never hear them,lol.
So now I have spent more money than I ever imagined, and she's still no faster. I got you an od tranny so you could be on the pipe thru the traps, yet cruise in quiet smooth comfort(2420@65). I got you waaay more mpgs with the 275* cam and the 3.15 final drive(4.56 gear).You'll be hard pressed to feel a power difference in the 275 cam at sub-65 mph speeds, but you will for sure feel the stronger bottom end. With a 10/1 Scr the bottom will still be soft with a 275,but with the 4.56s, I doubt you would notice it. And you're probably still sitting at 12.66@107. Yamn I hate me,lol.
