And how lovely smog is when it is blowing out your exaust pipe:D

So how much are the chips and programmer for the Speed density setups?
I figure I will end up getting a 92 or 93 at any rate.

BTW I had one more question that I thought of. What are the rear end gear ratios of 92, 93, 94, and 95?

What do most of you LT1 guys run in the quarter mile? I would guess mid to high 13's? Or better yet...what kind of trap speeds do you run? 102-103?

I had allready figured patience into the equation. First off I have pretty strict critera. It seems to me most Corvettes have low miles for their year, and I am looking for one with average to high miles. Also I am looking for a low price...but I figure something will come along eventually.

Chips are 5.50 from craig moates. They are flashable which dont require a eraser program. That means u can burn chips all day with 1 chip. An adapter cable to plug into the connection under the dash is about $40 and an adapter for the ecm is $45 to remove chips and change them very quickly. Getting one burned from ed wright is about $350 all the hardware to burn yourself is a bit cheaper. Some places sell chips for around 150-200
some shops will tune/burn cheaper than that.

Personally i liek 93s, why?? THEy are all 40th anniversary cars. besides the ugly (no offence) rubu red colors , all the vettes have the 40th anniversary emblem stiched into the seats. I liek the illumination orange because the LCD display is orange as well. The dash design is much better to my taste as well, more wrapped around the driver.

The gear rations are 3.45 i believe on six speeds.
My car stock ran 13.8 @ 103 mph on an average summer night. That was my best. Dont be surprised if cars run 13.9-14.1 @99-104 the altitude where u live may make the difference.
With drag radials i have seen a stock 93 run 13.5 @ 101 mph but i wont speak for all as everyone has stories... Just like GM hi tech performace says a bone stock 98 camaro runs 12s powershifting !!( MY BIG butt it does).

Good luck searching :cheers:

92-96 = 300 hp.

in 96 only, the six speeds ALL came with the 330hp LT4. Basically a recast head design with slightly raised runners. The cam was larger ony because of the 1.6 rockers.

The way the prices have ballooned recently for 96s it aint worth it at all. Save $10k.

95 vette = 300 95 camaro = 275
96 vette = 330 96 camaro = 285 305 ss package (310w/muffler)
97 vette = 345 97 camaro = 285 305 ss package (310w/muffler)
98 vette = 345 98 camaro = 305 320 ss package (325w/muffler)

01 vette = 385
02 vette = 405 02' camaro = dies with 320 max =(
(still not better than LT4 vette in 96)

The f-bodys arent as amazing fast as everyone thinks. they are heavy. Stories circle of superfast f-bodies, but not very many of the new vettes.. hmmmmm

in 98 i was in englishtown NJ at the Gm day shootout. The f-body camaros/transams w/LS1 ran 13.8 - 14.1s 100-102 mph bone stock. I asked one guy who had a drag radial on his car and he showed me his slip.. 13.7@102 he had 29 miles on his car!! .. and he turned out to be a owner of a dealership in NJ !! :blueangel:


Put it this way, doing the same mods to a vette will gain you 25% more. weight transfer, curb weight lbs, IRS vs DEAD rear axle (doesnt look live to me!) and looks are on the vettes side. :cheers:

I thought a IRS caused more power loss when transfering from the drive train? and why will the mods get u 25% more if its the same motor? because the cars lighter?

98 vette = 345 98 camaro = 305 320 ss package (325w/muffler)
so thats 25 more horse power for about 20 grand?

Is it the fact that the Vettes wieght is less that makes it realatively faster?

Same mods on a vette will give you the same power increase as they do on a camaro. Also the Camaro is way under rated. I guess you guys have never watched Z-28's dyno but I assure you they are not as weak as GM would want you to believe. They rate them lower so the Corvette looks better, but trust me, it's not that much better.

Don't get me wrong now. I'm talking pure power. Power is exteremely comprable between the two, and the 1/4 times are very comprable. Handling on the other hand is another story. A vette will hand a z-28 it's azz on a road coarse. That's where the IRS, and shorter wheelbase and better weight distribution really shine.

Sorry but these guys can't drive. They are good for low 13's stock, and that's the Beech Bend, just about the worst track in the country.

Again that depends on how you want to look at it. In stock form without any modifications, the Corvette 4-bolt block is stronger than the F-body 2 bolt. However, an F-body block can always be drilled to become a 4 bolt. In addition to that it can become what they call a "splayed" 4-bolt, meaning that the outer two bolts are at an angle rather than straight up. This is even stronger.

To my knowledge you can't make an existing "straight" 4-bolt into a splayed, however I could be wrong.

So a 2 bolt is actually pretty strong, the 4 bolt is very strong and the splayed, well if you tear that up you've just got too much power to begin with.

a 2 bolt block and is prone to failure when used for high rpms. other than that it is rock steady.
Splaying the 2 bolt block is BAD, thats why so many people sell them on ebay. The splays pull on a weaker part of the block which distorts the block and will warp it.

Vettes will enjoy better increases because of the weight, yes, and maybe a slight difference in freer exhaust/better cooling/intake charge to the motor. the gear ratios are more favorable as well. Al this adds up.

If you want a 2 bolt block motor with a dead axle and junky construction, f-body is the way to go. Buy a camaro and look up. Buy a Vette and look Down !! :eek: camaro :boxing vette :lol:

Just curious where you have heard this. I have no personal stake in it really, but I do have a friend who has converted his 2 bolt into a splayed 4 bolt. It's supposed to be the ultimate in strength. :confused:

I believe most people seem to think splayed is the way to go, if you've got some reputable results that say otherwise please share. It sucks when the common belief is flawed, although it does happen far too often.
