NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
Me and my buddy are to rice burners that went to the dark side. I wanted something old school so I got a 1986 Iroc (orig 305 5spd) with a 96 (one of the 300hp stock) LT1 and 4l60e (85k) tranny in it. It's got the ram air and chips. All in all it's pretty quick, chirps 2nd with an auto. My buddy got his 98 gt 5spd (60k) stock same day. It's only been a couple days so we havn't got the chance to race ((too worried about gas)). My ? is what kind of rwhp can I expect and who would win? Also what is my car worth (roughly) considdering it needs paint. we Will be racing sometime soon so will let know. BTW my names Chris .
----------
Oh and my iroc also has long tube headers, no cats, and a flowmaster. Sounds perfect.

Stock non ram air auto LT1s put down 230-240whp. With ram air and a chip you should be around 250-260whp.
When my car was stock, auto/non ram air, Mustang GTs weren't much threat. I raced a 2006 5spd and we were dead even all the way to 95mph.
Have fun with the car. Post up some pics.

You don't have a chip, it's a PCM so it's flashed with different settings.
Anyway, unless you're a complete 'tard when it comes to racing you're going to stomp him so bad it's not even funny.

Stock auto LT1's made 275 not 230-240 (no lT1 made less than 260 stock, i can promise you that)... if they did why would they replace the L98? And your starting crank at 275ish. you should be pushin over 300hp in the lightest Camaro gen, the third gens!!!

and just to let you know i'm pretty sure there's no such thing as a STOCK ram air Lt1, I have NEVER seen one, on a 98+ yes but 97 down no. Correct me if i'm wrong but i have never seen a stock ram air LT1....

the 230-240 number is RWHP, after drivetrain loss. and how does weight affect hp?
The LT1 ss's had ram air factory.

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
later on, i ported the heads and did a cam swap. and then put an LS1 in it. the LT1 now resides in my gta, and the camaro is a weekend cruiser.
and weight has nothing to do with power....
there was ram-air trans ams as well as ss camaros that came stock with ram air. thousands and thousands of them were made.

my car was a 6 speed with 2.73's stock. changed them up to 3.42's shortly after i got the car.

your going to have a hard time finding a stock LT1 putting 275 to the ground. most likely wont find one.

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
Did you also see that i wrote 98+? i know they made those! I've never seen a stock ram air LT1... also i DID state that i said they were making 275 at the crank, i didn't say to the ground and that other kid didn't specify either... and i said everything WAS AT THE CRANK! read a little more. also waht you run in the 1/4 with your LS1 third gen camaro?
they actually made more than 275 crank. 275 was just the factory rating.
the LS1 is now in my '93 camaro. it went 7.43 in the 1/8, never ran the 1/4.
the LT1 is now in my thirdgen gta. it went 10.14@131 in the 1/4.

Don't get snippy with me, go read the post I quoted again...it certainly makes it sound like you were also talking about the SS's in your "stock" comment. Don't forget about '96 SS's too

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
Thanks guys, here's some picks... granted its not much to at now but give me a min.. The guy I bought it from told me the car that he got it out of was one of the rare 300hp stock camaros. Possible?? It's got a K&N so I don't think it was the stock ram or they might have just changed the filter. Take a look and let me know what you guys think its worth. J/W if i got a good deal or not??

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
ifs it rare is not an LS1 or LT1 which rules those out and no L98 ever made 300hp stock.... so idk what bs he's feeding you.... no 300hp camaro engine was "rare" they only made 300+ from 98' and up and the LS1's were mass produced...

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
I remember a friend of mine had a 1997 LT1 WS6 Trans Am, it had a ram air setup and even said "Ram Air" on the hood. The Dealer he bought it from said the 97 made more power than the 96's and he had a HECK of a time finding parts for that car, alot of stuff was specific to 97. As for the 98 Mustang, yes a 305 TPI car will beat one I've seen it happen a few times. Those cars had alot of bottlenecks from the factory and it takes some serious work to iron them all out.

All About The 1996 Camaro
After a 24 year absence the Camaro SS returns as a limited production car built by SLP under contract to GM. Rated at 305 hp (315 hp w/optional exhaust), compared to 285 hp of the Z28.
RPO R7T (SS Package) was available through dealers, but was a non-Chevy modification by SLP Engineering. It included 305hp engine, special hood with functional scoop and forced induction, restyled decklid spoiler, revised suspension (coupes), 17x9" Corvette-style ZR-1 wheels with P275-40-ZR17 tires (coupes), and special badging. Other items available separately. Limited to White, Polo Green, Teal, Black, and Red.
It weighed in at 3,565 lbs. which was not exactly a lightweight, it did however manage to come out with a 0-60 mph acceleration of 5.3 seconds. It could also handle the 1/4 mile in 13.8 seconds at 101.4 mph.

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
There are 5 hp levels for the LT1.
Fbody had 3, 93-95 was rated at 275hp. In 1996, it went up to 285hp due to the dual cats. And also in 1996, the ram air cars came out and power went up to 305hp. The LT1 vettes were always rated at 300hp. And the Impalla SS/Caprice and 9C1 cop cars were rated at 260hp.
There were actual differences in the motors, the vettes had 4 bolt mains, and slightly better stock exhaust, and the LT1 in the caprices had iron heads, slightly lower compression, and a more torquey cam profile to move it's 4000lb car.
The 330hp LT4 came out in the 1996 Corvette Grand Sports and was put in a few Firehawks (26 or so actually) and Camaro SS.

and as far as tranny. The 4l60 is a lot better than most autos wrong/right?? Also is it worth doing the swap to the t56?? Thanks for your help and opinions guys.

But back on topic the 700's arn't bad trannies until you get higher than 350-400hp then you gotta start worrying, but do some upgrades to it and it'll hold 500hp easy.

I've owned now 5 cars with a 700r4/4L60E...in stock form they're junk. Like I said, once you start making some real power they don't like it.

well like i said the are FINE until around 350hp give or take some but anymore than that and the vehicle starts turning into a strip car only anyways, or a weekend crusier, so the tranny should be upgraded anyways. the Stock 700r4 is not bad for how many there are and how cheap you can get them.

To the original poster, can you post pictures of the engine compartment? It sounds like the seller may have been talking the car up a bit and it'd be good to atleast confirm that the car really had an LT1 swap.

Its true that a 700r4 with miles on it is not going to like a 350hp engine, however add a shift kit, trans cooler, and it will last a long time to come. Heat is what kills these transmissions. The stock cooler in the radiator isn't good enough, and the stock valve body doesn't help with its butter smooth shifts.
A trans cooler and shift kit help the 700r4 will easily handle a L98 for a long time to come without issues.
I don't know how much power my engine was making, however it would do 0-60 in about 5 seconds flat. Which I rebuilt myself with a friend, took a few tries but we got it right in the end. All I had was a stock rebuild with transgo shift kit, .500 tv boost valve, and vette servo. Had a stock torque converter as well. The trans had no trouble handling it.

Re: NewB/ 86 iroc LT1 vs 98 mustang gt 5spd
You call 350hp a street/strip car? Your expectations are really low. What about all those street driven LS1s mid 20s for milage, and still putting over 500hp out at the crank?

I agree with you, thats one reason i added the extra cooler for mine too, also i have a shift kit but its not in yet, i want a shop to do it cause i hear of ppl ruining their trannies trying to install the kit. (TransGO shift kit is what i have.) For every vehicle i have ever owned/driven (except an 04' silverado) has been under 200hp or just over. so 350 is A LOT to me. and 350-400hp on a carbed motor isn't gonna get **** for milage, LS1's are a different story, they are A LOT i repeat A LOT more streetable if setup right.
