WHat are the 11 second LT1 guys in here using to get 11's on stock bottom end?

Couple bolt ons and a 100 shot. Reliably all the time is a different story.

Check my signature. Thats what it takes me to run 11's.

NA..No Nos. Im looking for someone who is running 11's with cam and bolt ons or less.

i still have stock crank and rods if that counts? just pistons....my car runs mid to low 11's na

robb4964

You have an 11 second LT1 no dought about that,

But Im looking for people with stock Shortblock and heads running 11's. I know they are hiding around here somewhere..LOL

I am getting ready to start modding the LT1 and havent modded a LT1 in a while. I know high 12's are cake to reach but my goal is to hit 11's with a stall,gears,cam. Wondering what cam is doing the trick.

Silvershark

What suspension mods do you have done to your LS1 rob? I know you state it is a cam only car running 11's. Just curious what suspension setup your running, and full drag radials?

From what i recall there are like 2(sure there's more i only know of 2 though) people on this bored that have gone 11s with stock heads, na. Atljar is one of them, he was running the gm 847. It would be a whole lot easier to run 11s with some good ported heads and a custom cam.

While I think it's cool to see 11 second stock headed LT1's, I don't understand why people go through the trouble of modding an LT1 with lofty N/A track times as a goal and not plan on touching the heads.

If you're dead set on not doing anything with the heads get someone to custom grind a cam for you, that way you'll have the best chance of getting into the 11's.

If you don't spend money on the heads you're just going to have to spend it somewhere else to get to your goal- top notch converter, suspension mods, etc.

I was *that* close, and I spent 2 years trying to hit that goal. It wasn't my original goal but the car kept getting faster and faster so I made it a point to try and get 11's, but the car broke before I could get it and I changed my setup.

I went 12.06 @ 112.81 in a 3200 stall'd 3.73 automatic, running just a XE 224/230 (cc503) with boltons (minus electric waterpump at the time), and a mail order tune.

Had I had the electric water pump on my 4 12.0 runs I had, I would have made 11's.

A torque arm and Subframe connectors. Thats it. When the car ran 11 second times it had sticky tires but The clutch slips with sticky tires and the rear is a crappy 10 bolt. So she was launched easy with the sticky tires. I can pull a 1.9 sixty on street tires and with 1.9 60's it usually traps 119-120 and runs 12.0-12.2. To be honest the SFC's and torque arm should have been my first mod.

I know its easier to run them with heads but I am focusing a small amount on the LT1. I want to get the LS1 repainted and buy some heads for it so I am trying to get there as cheap as possible. I seen atljar run his camaro At edgewater a few years back. Wasnt sure what all he had done but I knew he was NA with stock bottom end. Not to mention his Z28 is gorgous.

I dont want to do any head work for now.

robb4964

Know what? I think you may have convinced me to change my goals back to an easily attainable 12.5...LOL..If I buy heads it going to be for the LS1.

robb4964

These are awsome cam only times man! I have a stall with a max stall of 2800 RPM's . Just bought it! I think I might sell my hotcam as I have been hearing alot of good things about your cam.

blkchevyz

all bolt ons, fms cam, cylinder head specialties heads, 9 inch and 4.30 gears.
engines got 93k on it.

once i get my high end miss fixed im sure i can get an 11.5-11.4 out of it.

Get heads for both. Get the LS6 RJS heads from Texas Speed for the LS1 and save LOTS of cash there. $1500 for H&C complete and you're done!
