LT1/L98 v.s. LS1???
A few questions for you guys. I am considering selling the T/A in the sig, in lieu of a C4 vette. I was wondering what I would have to do to bring the HP level of an LT1 or an L98 to that of my LS1?
The main reason for this is the cost of modifications. Am I right in assuming an LT1 or L98 power'd vette would be cheaper to mod than an LS1? It seems like when you add "corvette" to any aftermarket part it just about doubles in price. With that in mind, here's an example of LS1 prices:
Headers: $1000-1400
Heads: $2000-3500
Clutch: $800
Cam: $500
Thanks a bunch.

Cheaper yes. And it wouldn't take much to get there. Look at some packages to get an idea. Check out http://www.moreperformanceinc.com
A little pricey but I got my eye on that 396 LT1 stroker.

You must first come to grips with why exactly you would like a Corvette instead of an LS1 TransAm. Straight line performance or twisties?
You can get 350 HP out of an L-98 for less than $4K and much, much less if you do the work yourself. L-98 parts are cheap, LT-1 parts are more but the LT-1 is much farther advanced to start out. Buy an LT-4 and some will argue that you already have an engine that will hang with the LS1.
Good Luck with your choice.

I am looking for more of a straight line mobile. Don't get me wrong, I run the occassional canyon, but I'm more into the 1/4 mile scene.
I love my T/A, and it is fast as HELL for a stock car, but it costs SO much to mod. I'm tired of guys with less than 2k in mods walking me.
I don't want to shell out the change for an LT4 power'd car right now. I agree that a healthy LT4 will run with an LS1. Pretty mean cars.
I updated the sig. if anyone thinks the newer mods will make a difference.

Re: LT1/L98 v.s. LS1??? (PeteL)
My best time to date is a 13.94 at 104. This is at a 5000 ft elevation, and consistent with LS1 #'s produced here. That is something like a 13.1 at sea level. I did manage a 13.19 at 111, (low 12's at a lower track! :D) but that was with a 100 shot of the magic gas, which I no longer have. I guess I should of mentioned my extreme elevation, will that affect an LT1 or L98 differently than my LS1?

Re: LT1/L98 v.s. LS1??? (neat)
If you want straight line performance sorry to say guys but he should keep the T/A. Stock you make about 340HP, with LT Headers, off road y-pipe, catback and Lid (w/K&N), LS6 Intake you should be up around 400HP+,add some Drag Radials you should be in the high high 11's or low 12's with a 1.8 60 foot or so in good air. What's your 60 foot time? :yesnod: PS if I wanted pure acceleration I would have gotten a 2001 6speed Z28, 105mph+ trap speeds stock.

Re: LT1/L98 v.s. LS1??? (neat)
I figured an L98 could be turned into quite the rocket for 4 or 5k.
Heads : $1500
SuperRam: $1300
Cam: $300
Misc: $300
Rockers: $260
Pushrods & plates: $50
Throttlebody: $350
Headers: $600
Custom Chip: $150
That is $4210, and should get you low low 12s and a top speed over 180. :)

check the TPIS webpage, I dont' know if its still there but, their 85 vette dynod 343hp and ran like 12.10s.
If you don't wanna spend 1k+ on a Super/Miniram you can go large tubes and base to save a few hundred and still hit low 12s

Re: LT1/L98 v.s. LS1??? (95autoLT1)
Well, like I said earlier, I don't really want to shell out the cash for an LT-4 powered car. I am leaning towards a 1991 coupe. It seems like I could buy the car, and have a rocket for a lot less than I am paying now. I dunno, I guess I'll keep my options open for awhile.
Bear in mind that at this elevation cars run about a full second slower than they would at a decent track. Also, my track prep SUCKS. Old shoebox Chevy's with 24 inch slicks are only cutting 1.8 sixty's. My best is a 2.2XX. The auto LS1's with drag radials and a convertor aren't even cracking the 1.9's, they are still in the high 2.0XX range.
