School this cobra owner about LS1s please!!

[Musclefan21]

I am planning t sell my cobra soon and I have 97 LT1 to drive around and I wanna buy an LS1 in the spring.

Now, i wanna know what it takes for an LS1 to run mid-low 11s and trap around 120+mph (just like my cobra) without nitrous.

-what are common problems on LS1 cars?
-How many rwhp stock long block can handle? and how many rwhp stock shortblock can handle?
-how much does aftermarket heads and cam costs?
-if i do H/C/I + all the bolts on, would I have to built my motor?

-I will buy an LS1 around probably 60-70k miles on, would it be safe to do some major mods and still be safe?

-how long these motors last with H/C/I + bolts on?

and some other basic stuff, I need somebody to school me please.

thanks!!!

There are no major problems with the LS1. The most common problem is the 10bolt snapping with lots of power, or even in stock trim. The trans is good for about 500hp or so, but mine went out before that. Heads and cam differ greatly. The average cam would be around $400-450 and heads can go anywhere from $1000 to $3000 or more. AFR make some of the best heads on the market so u might wanna check thme out if $ aint a problem. U can mod the hell out of them at any milage. There are ppl with like 150k miles spraying and running blowers on their cars. U wull need full bolt ons, H/C and a stall converter if u wanna trap high. However iv seen ppl trap well under 122and still run 11's. DAM never in my dreams would i have thought i would see a termi onwer sell his car and buy an LS1. Theres nothing better than the sound of a H/C LS1 sitting at a light, but the whine of the blower on the cobra makes me shivver. Good luck and i hope i helped. Wait for Mr. Luos or another person to come on and go over any doubts u have with them.

i wanna a cheap fun car. my cobra already ran low 11s but she gotta go so i can save some $$ for some other personal things. so a z06 would be out of my price range. I will probably buy a T/A for around 13-14k or cheaper when I am ready.

I am giving my car away basicly. stock, 46k miles, (bought at 33.500miles, pullied at 38.800miles and returned back to stock at 46k miles) comes with ford 5 yr / 75k miles power train warranty. it has no issues and runs like dream! asking 22k.

$1100 heads, $340 cam.

$1100 heads, $340 cam.

and then tune?? and can I do heads, cam, intake, tune around 450-500rwhp and still have stock motor in 1 piece?

I know you're going with a t56 tranny, so that will help the rwhp. You won't need forged internals till over 500rwhp, atleast that's what most say.
Tune from lg - $540, tune + resonators install from RPM Motorsports= $300
Fast 90/90 combo was $1k

[Musclefan21]

also i wanna ask this, is there any clutch mods for these cars? my cobra has clutch cable, etc. i think T/As are hyrualic or something. so how do you adjust your clutch? if i get one, i would like to adjust my clutch so it will engage at the top instead of at the bottom or in the middle. anyway to do this?

they are definetely beast! i beat a bolts on 99 camaro with 4.10 gears, stall and 150 dry shot with only pulley, intake, midpipe & catback

to be honest, a cobra looks very good. a WS6 looks very mean and a cobra looks very sexy!

[nhraformula]

224/224 cam, ls6 intake, pacesetter headers, 3000 stall, volant cai, bfg tires and stock 3.23 look in sig at times.
my car is a very mild set up. with a set of heads and a slighty bigger stall, i would be able to do mid 11s all day.

there are no real bad problems with LS1s.
beat on them just like any other car they will fall apart.

With a big enough cam like a G5X4 you don't need heads to accomplish this.

Cam has a LOT of lift....well over.600. Issues with the heads...

What issues? I know a few people running it with stock heads.
