LT1 or L98

[vigman]

Actually

It'a a piece of natural quartz crystal with natural fractures internal of the globe.

It sits on a base with 12 different colored LED's in the base.. and the base also rotates the crystal and the leds dim up & down slowly and cross fade between the colors too!

It was a gift from a bud...

75 for the crystal and 55 for the base.

Now I don't do the wind chime.. burn incense read tea leaves thing... but I think it's VERY cool to watch.



Vig!

I have yet to see a stock L98 walk a stock Lt1, even though the tourque peak is 800 rpms higher on the LT1 it is still making over 300 foot pounds at 3200 and the LT1 has between 40 to 50 hp more than the L98. I ran a bunch of L98 cars with my auto 95 and the only time they jump out a fender on me is through 1st gear if there are running a 3.73 rear. By third gear I am usually a bunch of car lengths in front. My car is mostly stock and runs a best to date of 13.4, and at 100 MPH its 14.6 feet per every 10th and I usually run a few 10ths quicker than stock L98s.

As for the Opti-spark issue, its silly to avoid an engine that puts out about 50 HPs more because of a misguided belief it will fail. Its still a distributer for a Chevy 350. You will spend way more dough adding 50HP to an L98 than replacing an Opti on a LT1.

I have nothing against L98s, had a few myself.

I gest picked up the latest copy of Hot Rod magazine. Its cover feater is the top ten rod's of the year. One of the ten is a C5 vette that has a 700+ hp motor in it. It is fast buy anyones standards. It made me fell antiquated to be on the net to be debating as to witch is the fastest a LT1 or a L89. In the same isue it taulkes of the last Comero to roll of the asembly line. A truly sad thing to me . The redesine of the Camero and Fire Bird was what I fill was the reason to develop the LT1. Dave McLellan ( corvettes chief engineer ) had taken a L89 and a ZR1 to Texas and broke 20 exsisting speed records. six of them with the L89 ( how does six hr. at 176 mph sound ? ) L89 corvettes domanated SCCA and was finely but in ther one class because the Porca prepeys was tired of lousing at twice the cost. The land speed record for the fastest productin sports car was set in a C4, not shure about the exact engiine combo but it was not a ZR1 and the LT1 was not out yet. The motor was not stock and was blowen. The car ran in the high 260's and the body was stone stock. That's fast. My point is that GM had no point in Engine Development. With in reason I think it fare to say Dave McLellan has beat everything ther was to beat. It is untrue to say that any LT1 will beat any L89 IN stock or any other form. If you are a mecanic or turner you whould know potentaly bouth cars can run pretty desent. Lt1's drive the distributor off the front of the cam because of desine limatations of the F bodys, check one out you will see. their was no enprovement to the electronics in the distributor, althoe redesined for cam drive it parst funtioned the same as a HEI. timing and advance is controled by the knock system an the ECM for bouth. So to say that there is any proformance advantage to the OPTI SPARK is douthfull . Now if you want to debate if the higher compresion or the cylender head's hart shaped combustion chamber ( were the Vortec desine came from ) of the LT1 added proformance then you are on the right track. A set of flat top pistons in the L89 gives the same results ? so I dont know were to go with this but I will say that I have a L89, it a blast to drive and I have never wanted for a LT1 or a LT4. the best advice is to get the best vette in the best shape ( low miles, great int. ECT. ) that you can. L89 or LT1 you are gooing to love it . and my wish for all corvette lovers is a new Z06 for Chrismas this year. A 57 fulie wouldnt be bad eathire

My mufflers are quite loud, but they sound so sweet when I gun it around 2600 RPM's!:L I guess it's a fair tradeoff, nice performance for a little noise.

Just curious, were you drunk when you typed this ? -lol
Good luck with your L89 engine.

Another note here

The LT-1 will only make MORE hp over 5K rpm

this weeks Corvette car's & parts has a great article about the LT-1.

Important foot note
You drive on torque...you measure horsepower.

Vig!

 

[Vettelt193]

It really depends on how you drive.... The L98 is a great engine, but there is no doubt that the LT1 is better. The only benefit the L98 has over the LT1 is the torque it can make under 2500 RPM... after that it is LT1 all the way. So, if you drive your Vette easy, L98 is more fun, because it has the power in low RPM where you will use it.... If you drive your Vette harder, LT1 is better, because it has gobs more power at higher RPM.

The opti-spark is not as bad as some of the L98 owners are making it out to be. Yes it costs more and is harder to change than the L98's system. BUT there is nothing that says it is going to fail.... I had over 100k miles on my '93 before it gave me any trouble at all, and even then it may not have been broken (I had another problem that seemed like opti spark problems so I changed it out) Some have problems, some don't.... just like some will have problems with the L98's system while others won't

" Naw" were'nt drinken, but it was late at night.:eek :eek :eek

It's hard to reply to these post's when you can't spell worth a you know what ......." how would you like to be my english teacher ? " ........ " Man could I blow her mind "

:J :J :J

sound's like you might have a ballsey vette , how do you like the converter and have you ever wished that you hade'nt went so low on your gears ? :confused

At aney rate I here Edmond need's a sky hook to fix his mufflers with ........ got one ?

 

[vettn94]

how do you like the converter and have you ever wished that you hade'nt went so low on your gears ? :confused

The converter has drastically improved my 60ft times.
I'm pretty happy with the 3.54 gear, my ET improved by over a half second and I gained 5mph in the 1/4 mile with just the gear change alone.
The 3.54 and 3.73 both seem to work great with the LT1's tq. curve.
Remember your L98 has more low end grunt than an LT1 so either gear is going to be lower in your car.

jimmie,

It's up 2 u, but u might want to change the L89 > L98 per your Corvette's description in your profile.

l98 vs LT1

I had a 91 6 Speed and it was quick off the line. But around 4000rpm, it just hit a wall. Sold it and bought a 93 6 speed. What a difference. I have 85k miles and no Opti problems...

Go with the best Vette you can afford

 

[blackchevrolet]

If you were planning on getting big hp on a c4 say, in the area of 500+ hp, which engine would be better to build into a racing motor?

 

[Mad-Mic]

L98 you can make big horsepower with if you change out the TPI with a super ram or mini ram and do the same build up you would with any other car. i have a friend with an 86 vette with a mini ram 383 stroker motor running 11.70's. they will run if you build them right and match everything.

can't say about LT-1's but i would they would be a bit more expensive. i'm sure the LT-1's can run big numbers also.
