What kind of power does it take to get an E-Body into the mid 11's?

[uthustler]

Yea, big goal there for a cruiseable, streetable E-body. But those are my long term goals for the 1970 E-Body that I eventually get. Id like to get into the mid 11's with a 4 speed. What kind of power do you think it will take? Im thinking it will need atleast 600 hp. What do you think? Im thinking big block for sure.

[Chryco Psycho]

actually with good suspension / traction probably less but 600 would be a good target range

[Carlwalski]

I agree.

I may also want to consider looking at the stroker small block option to to save a little weight.

Shouldn't the question be what kind of money?

  Just the cost for sfi and safety equipment add up. Please remember to stay on top of the safety requirements to get a car into the elevens. Right down to long wheel studs and lugs, fire ext, fuel and electrical cut offs, blow proof shields, safety loops and many other costly items.  A 10-1/1 comp engine will take you into the 11's easy with ported steel heads, good cam and intake, susp., and gearing. 

Keep safety number one when building your go fast project.

I believe that 57hemicuda was in the 11's with his 5.7 powered '70 Cuda vert.  That could be another option.  I dont know what he was putting out for hp though.

If it's a street car, with marginal gearing and handling type tires, and your last name isnt "Sox", then you will need sumbstantially more to get into the 11s. Because you have to overcome the obstacles those marginal (for racing) parts throw up. Also as mentioned, you will need a driveshaft loop, and a blow shield, plus the SFI flywheel and balancer. I would consider that mandatory safe stuff with a stick shift car that has that kind of power (In addition to mentionned, you really need some kind of rev control. Racing leads to stresses that can break things, even with stock engines, and rev control saves parts...) In terms of a number, 550 pound feet of torque, and 500 hp will get it done IF you can drive, and IF the car can stick on a track.

it wont be a track car, cruiser/driver on the weekends.

My '73 Chally with a stock 360 rebuilt with a tunnel ram and 2 390 CFM holley vacuum secondary carbs,Magnum Comp Cam ran a 11.83 with slicks ,stock rear suspension and 4.30 gears. plus a little shot of NOs!   

[uthustler]

i dont want NOS or slicks, most id do is drag radials, but no NOS. if I have to, ill do a big block turbo build up.

[nivvy]

500HP in a 3700lb car will just get you into the 11's.....good driver of course!

[moper]

So you think your feet will notice what road you're on if the flywheel explodes? Or the car will land on it's wheels after the pole-vault if the front U joint lets go on the entrance ramp? You're not talking highschool cars anymore. that kind of power is nothing to relax the safety stuff on. Also, the reason race cars are using drag radials is because they have the same amount of traction..hence the safety parts...

[oldkimmer]

It takes 425 hp for a 4000 lb car and driver to run high 11s with slicks...... safety 1st thou..........kim.

[nivvy]

That would have to be 425 RWHP .... 

[moper]

Yeah, RWHP. But, that's still only 490hp at the crank with a stick. That's hydraulic cam, pump gas iron heads range. But, as an example, a 440 (71 Cuda) I did that dyno'd at 480hp at the crank and 525tq at 3500, with 3.54s and a stick, runs mid 13s...at 110. Thats because the driver is not the best, and the car is not set up to drag race. It's a nice fast cruiser.
