your thoughts
Thanks guys. I have an 8.75 with 4.30 gears. And 28x9 slicks. Also a 3ooo or so stall. I would need to get an alum intake and headers I also have a 750 carter competition carb or an 850 street demon. Kim. Hope this enlightens u guys. What cam ?would work best
A 12.9 with SS suspension is around 103mph.The 4.30s will hit that at 5133rpmPlus TCslip,say5400, with your tires.
With street suspension, you would need to aim for a 12.4 which would be around 107mph. the 4.30s will hit that at 5333+slip,say5600.
To trap well, you might want the combo to power peak say300 to 500 rpm lower, or 5250.
Now you're getting into trouble.
In post #8 the math puked out 350hp, and the 4.30s want it at 5250.
Is it doable? I think so, but just barely. It would be easier up around 5600/5700 but that combo will want different gears.
The peak at 5250 is about a 225ish cam
The peak at 5700 leads to a 240ish cam
Sound about right boys?
The 240 cam will take your street suspension down into the mid 12s, cuz now your making closer to 400hp, perhaps a little over, depending on your headwork.
So as a compromise a cam of around 232 could get you a peak around 5450, and then you won't be overdriving your gears too badly.And still firmly into the 12s. You will have trouble 60footing it.The 230/235 cam has made over 400hp.
In a 3500pound raceweight car 400/3500=.114 which puts you down at 11.8seconds with SS suspension,12.3ish with street suspension.
And the accompanying mph is 113ish; which might be 5632 plus slip,say 5900. I'm seeing success with the 232ish cam.
As an aside my pig-heavy Barracuda(3450 me in it, and 200 pounds of stuff stripped
off it) went 93 in the 1/
[email protected] with a 2.2 60ft. Somewhere I once read that you can take your Eighth mile ET and multiply it by 1.57 to get an idea of the 1/4 mile ET. Well if that is true, then my car is a 7.92x1.57=12.56 second car;with the 2.2 60ft and all. But even if the 1.57 is just close, the car is still firmly in the 12s.
My 360 has a 230cam,is a zero-deck, and has OOTB Eddies.Well it was a zero deck; the pistons are now .005 up,or so.That makes her about 10.9Scr.
Go man go!
Ps, very streetable, even with a 4-gear.
I have a 10.97 starter gear tho.......... She will idle down to 600 with the clutch in and her pulling. After that I kinda have to put a lil slip in the clutch cuz she's losing torque fast.I can mash it at 2500 and light up the 295s(750DP). I think I can mash it at a lower rpm, but I've never really looked at the tach,lol. 2500 in first is 30 mph and she definitely lights em up at 30. I bet she'd do it at 25(2100) or maybe even 20(1670). Heck she'll do from a dead stop with a bit of a burp on the throttle to put a bit of inertia into the flywheel,lol. Point is, it is very streetable. It vacuum peaks at around 2200, and that is what I have her geared for at 65mph.(GVod). It ain't great on gas but I think she is now as good as I can make it.
Big street-fun.
