you needs a traction anvil!

I took the easy way out........ stock LS7 with a CAI and stock clutch in a C6 Z06
10.84@128.94 MPH

Tuskyz28

Yes you did

The trick is to make a road racing chassis want to behave at a drag strip...... power to weight can only get you so far in 1/4 mile drag racing with a manual transmission car with an IRS

jayyyw

Care to explain?

Tuskyz28

Vettes have a better power to weight ratio over a Fbody to begin with. Not hard to take them to the next level.

Already dual exhaust. More efficient drivetrain. Less intrusive cowl.

Ive had a 4th gen Fbody, 2 5th gen Camaros and a C6 that Hiossilver and I have done all the work to. Hands down C6 is the easiest to work on and make go fast. We took my C6 to 11.0 @ 125-126 with 100% stock exhaust and basic bolt ons and didnt even have a complete poverty drag pack lol

fnbadaz06

I generally agree with this, though I guess we need to define what the "next level" is
In the late model Corvette world, 9's are the new 10's, which is quite a feat for a manual transmission car with an IRS rear suspension that's not designed to be drag raced in 1/4 mile racing.

Yeah corvettes are cheating lol.

I got 20k miles out of that combo despite claims a .015 over stock 5.7 sleeve would never hold or a 4.100 crank would have piston rock or some sht. Went 10.19 @138mph on a 120shot with T56.

Tuskyz28

I loved that combo. It was different and it delivered

Looks like lazer and darth splained it pretty well.


irs is a good thing

Worst part is not being about to get enough gear in them for high rpm engines.

fnbadaz06

IRS can be a good thing if the parts are designed to handle such abuse.
We finally got the options for 3.90 and 4.10 rear gears for the stronger Z06/ZR1 cases, which will help a lot....many went the option of changing transmission gearing to accomplish torque multiplication, but Vette drive lines are just not designed with 1/4 drag racing in mind.

No need for a solid roller. 750+ on the crank dyno here and still hydraulic

Darth_V8r

iTrader: (4)

Agreed. I prefer solids for rpm not power. It is a distinction, but important.

ramairws6

iTrader: (33)

I agree. My next build will definitely be solid roller and a lot more lift with crower rockers. I had everything from my last combo which worked real well so I figured why upset the stew by throwing in Brussel sprouts! Hahaha

my best time with a stick and 6.0 was 11.32 at 123. 1.59 60 ft

swapped.to a 200-4r and 3600 stall and slowed to a 11.60 at 118. Sent converter back and stalled it to 4600 to get back to high 11.3s.

changed 241 heads that had mild port work to Darts hand ported. Picked up 26rwhp and went 11.21.at 121
changed converter to a 5600 8" fti to go 10.91 at 122 at 3850

honestly I dont think with this 4l80 and 8" converter I have behind this 427 is any quicker than I'd be with a 6spd manual. And on the street I was out running all the automatic cars who had to pedal to much. When you know how to drive a manual, launching it and rowing gears it's hard to beat.
I only went auto because went through clutches and my rear gears howled like a banshee

stuff wall is still a bias ply.
I ran a drag radial but it was very hit or miss and hard on parts

fnbadaz06

In my world, auto swapped C6 Z06's pretty much decimate any manual car with equal power......just no way around the need to slip the clutch on launch and the loss of power to the rear wheels when you have to hit the clutch 3 times in a 1/4.
1/4 drag racing is all about the first 330' (with regards to ET).......auto swapped Z's run mid to bottom 1.3 60's easily, and are pretty much high 9 second cars right from the get go.
They'll give up a few MPH in trap, but that doesn't matter when 1/4 drag racing is all about ET and getting to the finish line first.

There are some tricks we can do to help the launch and speed the shifts up....even some have run face plated trans, but it's very difficult to make up the advantage on the short times the auto can have on you.

Now roll racing and standing start 1/2 mile and longer is a whole different story.
