I think it would be interesting to see what wheel horse power guys are making with their little ol C4 corvettes and what mods it took you to get there.

Post what ya Got!

Thanks Tequila Boy. I think a post like this, IF guys add their mods, would help alot of guys looking for l98/lt1 proven combos.

Hmm interesting, I don't know mine , won't know till I take it to a dyno in the spring. What does a stock L98 put to the rear wheels before mods?

Lt4 383cid
Port and polish stock heads
Port and polish stock intake

I believe most guys got 240-260 RWHP out of their stock L98s.

smooth1990

What dyno did you use?

Nice numbers with stock heads!

Tapio@FTTRacing

Dynocom dyno.

Yeah, stock lt4 castings have huge potential once ported!

cmashark

380. Previous owner did the work (see signature), I wrote a check...

I'm in the middle of an LS1 swap. Hoping its close to the same.

Try more like 210. L98's are ~240 CRANK hp....not rear wheel.

Mine is 278 RWHP. All I had to buy to get that was a stock, 150k, '92 Corvette.

smooth1990

My mistake. I thought the L98 was 240 at the wheels...

FASTAZU

430rwhp 380tq,

Headers, Corsa's, Ported intake thru heads. 63mm throttle body.

Red89'-L98

That's all? It seems like you would need a lot more than that to get those numbers although, I could be wrong.

FASTAZU

510hp 350 package.

Every time I see you put those stats down I think about how impressive that is! And your car runs low 11s right? Thats pretty awesome!

Whats she weigh anyway?

93 ragtop

Thanks for the compliments. Will (rklessdriver) did a great job picking parts, and putting it all together.
Not sure on weight. Its all stock vert with a hardtop so its pretty heavy. My best run was 11.19 at 124.6x. But we were having problems with it cutting out and shifting early. I hope to get back to the track soon, maybe feb. 7th, and better those numbers.
BTW that is on e85. Was never dynoed on pump gas. Ed figured I would loose 10-20 hp on gas. If I get to go to the track feb. 7th, I will have 6 hrs to play, so I plan on trying both fuels to see what difference it makes.
