Hey fellas,

As the title suggest i want to run 11.50 or better cam only. Car is a Holden Commodore (4 door pontiac GTO) LS1 A4.

My only mods so far are 1 7/8 headers in to a 3" system and a 4k converter. Ive run a best of a 13.4 at 100mph. Car weighs in at 4100 pounds. Shedding weight is not and option. The way it drives on the street is how i race it at the track, with the help of slicks though.

Im getting diff gears and a trutrac next week. Either 3.9s or 4.11s.

Ive got an intake ready to go. All im unsure about is which cam. I was thinking EDs Streetsweeper??

Can anyone weigh in?

At 4100 lbs I'm thinking maybe not, but who knows...it could be very close. Depends on the track as well

I don't see it happening. It would be a huge struggle even if you lost weight. It might be possible if it weighed 3600lbs or less and you had some good air.

Thats a tank @ 4100lbs! Mayb 12.0s

Its just as heavy as the GTOs no?

GTOs are in the 3700-3800lbs range and can easily be lightened some. I wouldn't be any more optimistic about a cam/bolt on GTO doing it than your car either.

It takes a lot of power to move the weight and launching hard enough to get it done starts to get dangerous for the IRS.

I have to agree. If it didn't weigh that much, I'd say it would be possible, but not at that weight. But.... You never know until you try.

Put a 150 shot on it that should get you there.

So how does your car weigh 4100 lbs OP?

You can run high 9s cam only in a 2800lbs F-Body... but you wouldn't want to drive that on the street.

In a 4100lbs... (are you sure it's not a Challenger? lol) 11.5 is going to be hard. Maybe with heads and really good air...

I am struggling to get mine to go 11.59 with 3650-3700 raceweight (me in the car) in the DA we see (1800ft+, usually high 2000s) and I have some mildly cleaned up 799 heads too.

mkvamso on here has a ls2 GTO with a small stall and a magnuson blower on it trying to get 11s on drag radials

cam only ls1 at your weight I wouldn't even count on 11.99 unless every little factor in the car, track, and weather is working for you

What gears should i go with?

I dont care about fuel consumption or revving hard on the HWY. I just want whatever suits my setup.

4.56 ftw

ls1 1990 VN

Hahaha!

I can't see him wanting to use that gear.
It'll make a nice open road Aussie cruiser for him lol, be thinking he had a few more gears to go.

i don't think you can do it at that weight

If you're only running mid 13s with headers and a big stall then you're not even close and a cam isn't going to gain you 2 full seconds.
