1998 Corvette 85K miles, will start as a street car but at some point be a track only car, in the mean time I would like better 0-60 times.

Small to mid sized cam (224 range)

or

Stall, Edge or like, (3200-3600)


Open to other suggestions too. Thx

 

Thats kind of a tough call but I think the converter would probably be a better starting modification. It will help a lot with your launch and if you decide you want a larger cam later on down the road you will have the capability of running one since you have an aftermarket converter.

 

stall, cam/bolt ons only my car was lazy out of the hole (and couldn't spin a tire at all)...slow as hell until around 3000rpm

a stall will be a world of difference

For reference:

cam/boltons stock stall my 60ft at the track was 2.0-2.1 dead hooking 8.3-8.4 ET @85mph

added a Yank SS3600 and 60ft at the track was 1.9-2.1 spinning like a madman 8.0-8.3@86-87mph

added some Nitto 555R 275/50r15 drag radials and got 1.78-1.79 lightly spinning 7.89-7.9@88-89mph

most recent was a 1.7760ft on 325/50 mickey thompson DR and 7.80 1/8th @ 89-90mph

 

This may not seem relevant to everybody, but my first mod to my '95 Z28 was swapping in a 2400 stall I already had. It was great fun, with effortless wheel-spin, but once I was going about 20 mph, it was exactly like being pure stock. I know, because I raced my buddy's S281, stock and convertered. From a 25 mph roll, both times, he pulled away before the top of my first gear.
But running a decent cam with a stock converter isn't so different from waiting for a big turbo to spool. Really, it's like waiting for a ProCharger, with way too small of a crank pulley. Across the intersection, you fall behind, and then you're up, and by the top of second, I couldn't wipe the stupid grin off my face. That wasn't my '95 Z, however. Still, educational.
Jumping out in front then falling behind, versus falling behind then pulling ahead, that is the choice. At the dragstrip, I prefer the cam first. On the street, I'll take the converter first. Because sometimes, if you jump, they give up. Then you don't have to break the posted speed limit just to win.

 

Tires.

 

Stall and sticky tires.

 

Stall WITH tires.

 

For what its worth my car is also a helluva lot better from rolls now too.

Pre-stall buddies 6 speed car would pull me slightly.
After stall I put 1-1.5 cars on him from bottom 2nd no downshift rolls and 2+ cars from 50mph+ starting rolls.

I drove my car cammed/no stall for over a year and it was terrible. Slow, dead in low rpm, and VERY hard on brakes.

 

A stall will be more beneficial in my opinion.

 

Reviews say 0-60 in 5.2, with stall and tires, are we talking 1/2 sec off 0-60 4.7 4.8?

Thx for the responses so far.

 

I'll throw another option out there, gears...especially if you have 2.73s, you can swap in a 3.42 diff from an 6-speed vette

 

Stall and tires . I dropped 7 tenths with stall only. 0-60 HUGE DIFFERENCE WITH STALL. You will like a big stall a million times better than a cam with no stall. Cam with no stall sucks trust me

 

Ok, what size stall for best 0-60 times?

I will also look into the 3.42 as well, but seems like the stall is the ticket.

 

If it was a question of gears versus stall, I'd still be torn. But I'm 95% street, 5% race. If yours is the 6L80E, then I'd agree, converter is first.

 

Do both

 

If you already have 3.23's than just get a stall

 

Auto needs 3.7s 6sp 4.10s check out what the Aussies use with their Autos

 

I didn't think before, but now I notice it's a '98, so it should be a 4L60E. Yes, I'd want a 3.73:1 gear, or the closest ratio available, even before the cam.

 

switching from 2.73 gears to 3.42 and a 3600 yank gained me 1.1 seconds in the quarter mile with no other mods

 

are you doing any future mods, or is it just this one mod and done? if you do the stall now like a (3600-4000) you will be set up to run almost any cam down the road without having your trans being the weak part in performance. Switching the rear gears will be huge as well for getting your car off the line, but you still have to plant the power which for the streets the MT et streets seem to hook the best, just don't plan to drive in the rain very fast lol
