LS1 F-bodies aren't worth the price you had to pay to get them new either, IMO. My window sticker is $25,600! Sold for that much in late 1997! Good thing I bought it for ~$15k when it was three years old with only 32k miles.

yeah, but look at the depreciation of cobras. i mean there are people still asking and getting 18k for 01's. And they can't take an f-bod. Really, im not just saying this because i own an fbod (i own a stang GT too) and the f-bod is the best bang for the buck anyone can buy.

Gotcha!

I have many friends who have Cobras and all of them dynoed close to 400 rwhp in bone stock form. One of my real good friends and semi-rival just dynoed 441 rwhp and 488 rwtq last week with a stock pulley, cai and a cat-back.

I agree. I got mine for right at 17,000.00 after the taxes and such.

TEA's are affordable power makers every time.

I have been hearing a lot of good things about TEA's. A very reputable mechanic who works at my local Chevrolet Dealership and F-Body Enthusiest said for me to look at those heads. Thanks for your recommendation.~ L.B

I have been 4-0 against 03+ cobra. I have most basic bolt ons and a tnt 100 shot (120 actually) 2 of the drivers where extremely good. The cars were putting down ~480. They have now reached 550rwhp w/ the ported eaton. For the kbs you will definetly need nitrous and h/c. You will need less hp than they do to run the same times.. A stalled car will have no problem against a M6 fbody and should be ok w/ the cobra. I actually pulled away from the cobras I run in my 3rd gear and I didnt have a stall back then.

My son has 03 Cobra convert@4k# race weight/pulley/K&N/catback/x pipe/nitto's/after market shifter/dyno tune/448 hp. I drop him 6 out of 10 because I pull hem early, he pulls me on the high end BUT he is 0.070 faster( THIS makes a close race) when we compare our FASTEST time slip

to be safe i say you just run a blown/turboed/built bottom end 400+ cube monster
Um, yep. That would do it for sure .

Yep. I seen the site and you are absolutely right. But a good paxton will give one of those Cobra's a very serious workout.

I have heard of the AFR LS1 heads. But the problem with that is I can't find anyone who has forked out the $2200.00 + for a set of these heads, nor can I find any feedback from a consumer on these heads.~L.B .

Forgive me for asking, but when you say h/c, do you mean "high compression". Let me know. I am really interested in how you are beating these guys. The one around here still has the regular Eaton blower, gears , pulley swap and a program. Let me know what your recipe is. Also, feel free on what I need to do in order to make the necessarry adjustments to mine. My ingredients are as follows;
SLP LM Exhaust, LT Headers, No CATS or Aftermarket Y-pipe(stock Y-pipe); Hypertech program; Diamond Point SLP Subframe connectors; SLP Cold Air Kit; Strut Tower Brace; and a Brand New set of BF Goodrich Drag Radials(The good ones)...... Now awaiting your critisizm

This is what every LS1 Equipped Camaro needs to do! If you can make it do this, an 03 Cobra owner would cry! Click on the link and scroll down to bottom where it says "go for a ride" and click play! man! That thing halls ***! A true "RED ALERT" for any Cobra!~ L.B.
