thanks you all for you input on this. my reason for asking this was because i wanted to keep my 85 as stock Looking as i could but make it as fast as i could doing it. i never planned on racing my vette and i wanted to have the power there if i ever did. but after i went and saw "PINKS ALLOUT" and i saw these 10-11 second cars running on 10 1/2 street tires i was a little hooked and i think i got bit. now i am planning to build and want the facts in front of me before i do anything.

my next question to all of you who are telling me that the 4+3 is going to really be a problem.....may i ask why. just so that i know

guys/gals i am no vette expert by anymeans...all i know is what i want with no reasoning behind it other then my own

i have a 85 z-51 4+3 thats in pretty darn good shape other then a few mechanical problems.
i dont want to get into swapping the engines and tranny's
i just want the most out of the current setup
maybee im kinda looking for the sleeper L98 4+3

 

Through this thread...YES I was talking a swap of motors - that will need to take place to get it into the 10s - you could use the stock block, build a setup like Corkys and be there if you match it to a T. I am sure Corky could build 20 more of them with the same components and have them all run within .1sec of one another. We proved that when we built our 406s that ran within .0X sec of one another.

To keep the long runners and stuff - again that is using 20 year old technology that is not really that great in terms or comparison to what there is today.

To keep all those restrictions in place- and taking l98 to the most stringent extremes - there are ways to do what you want....go to the super stock forums and you will see cars with "stock" motors running in the 9s - but they are 40K dollar motors after all is said and done and while having and appearing to be stock - they are anything but stock. They have acid etched heads, 700 lift on the valves with .300 lift cams that send the lifters sailing off the cam - in order to get the lifts they need and stay within the "stock" lift criterias!

With the limitations of "stock" you would be spending TONS more than it will already cost you and the best you will probably get unless you can get someone to take you under their wing that has already been there is probably low 12 high 11 if your lucky. Lift those restrainst and you could have a low 10s car that only has a motor changes and trans change. 99% of the people that look under the hood have NO CLUE what a corvette motor looks like stock anyways.

Furthermore you can do a WHOLE lot on a 10.5" slick -again its attention to detail. Here is our nose heavy 4000lbs chevelle with a 555CI motor on a 10.5" tire! PLease note the starting beams at just infront of the guy at the starting line and the car is just passing the 60' mark. On that run it went 180ft down the track on 10.5 tires! Lets just say that was the most fun I have had in a long time on two wheels!

 

10 sec?

4+3 has to go.

IRS will give you something to think about.
Depends on how many times you go 10 sec.

Better to have a low 11 sec N/a car then use the NOS to get the low 10 when you want it.

More streetable that way, plus a low 11 sec street car is fast anyway you look at it.
Most guys that come up to you on the street saying they have an 11 sec street car are .
(NOTE: I said most, not ALL)

Plus I am talking motor swap too.

Low 10's with your current motor would be hard.

Or you could just buy my car in the C4 for sale section..


Good luck on your project and let us know how it turns out.

Whats your combo these days? (cam, cr, heads) and what are you running for an ECM ?

-- Joe

 

Its a lot easier and cheaper to run 10's using a carbed engine. Big block would make it even easier, but probably no where near as cheap and you can count out driveable on the street.

 

355 11.5 comp 236 at 50 solid roller 600 lift a hand set of ported afr 195 heads around 200 cc now stock 85 ecm with the same chip i allways had since my first 406 was in her and still 307 gears to boot

 

What is your definition of "lots"?

 

You and Jesse must be blessed. I've always been impressed with just how fast your combo's are.

11.5 is a ton of compression for a 236 cam. Whats your overlap like? That thing must have the perfect combination!

-- Joe

 

'Lots' was subjective in my post, but from dictionary.com:

Often, lots. a great many or a great deal: a lot of books; lots of money.

That's probably how I would define 'lots' as I used it. You could substitute common, attainable, not impossible, or any number of other terms if you wish.

If you're looking for a numerical interpretation of the term as I used it, we'll use 10%. On any given Friday or Saturday night, the local street hangout (here in Raleigh, NC) will have 25-30 cars looking to engage in illegal speed contests. Of those cars, we'll assume 30 for this scenario, 3 of them will be capable of 10 second slips and being daily driven.

If you prefer a larger scale, I'm not an authority by any means, but I would hazard a guess that there are somewhere between 20,000 and 30,000 daily driven 10 second cars in the Unites States. I am quite literally guessing, but I wasn't prepared to define my subjective use of the term 'lots.' Perhaps I should of used 'not very many' or 'there are some' or some other subjective term. I suppose, the completely appropriate thing to do was to not use a subjective term at all, in which case I would have to withdraw my 10 second car comment because I have no empirical data to show how many 10 second, daily driven cars there are in the world.

Instead of conducting a study on the number of daily driven 10 second cars and their quantities, I chose to foolishly, subjectively identify their quantity as 'lots.'

My humble apologies.

 

 

That's funny right there!

That is one of the best, well thought out , absolutely hilarious responses that I've read here in a while

TO be honest with you, I've been around the street racing scene long enough to know..anything that runs faster than mid 11's, you usually don't see on the street..unless it's someone running a HUGE nitrous kit (which I've also seen a lot of; people spraying 400hp PLATE kits!)
I actually retired my vette as running an 11.50 and completely dominating even the "fastest" car that people had to throw at me (prochaged LT1 camaro)
I'm not sure if you've ever RIDDEN in a car that does mid 11's...if you havne't give it a try, it'll give you a whole new perspective of "going fast"

 

"Lots" works for me. LOL

there are soo many people that talk a big game but at the end of the day there cars aren't really that fast. i have done alot of lurking on street racing and track racing and raced people that were supposedly the fastest around and very few cars straight ran like hell and those few were only brought out to walk the walk then parked in the garage for a few months. but the rest of which was a good majority of these cars were really not worth pulling out of their driveway. they may have been fast 20 years ago but not by todays standards or they just owned by people that had no idea what a fast car really is. and like mentioned earlier its not hard to build a 12 or even an 11 second car its past that point that takes some knowledge or nitrous or both..lol
