Hey Guys,

This winter i will be doing a full build on my 89 vette. A close friend of mine has built his own 383 stroker vette and he will be helping me do the same with mine! I have already discussed with him in length the process of it all and we have discussed parts but i wanted to get a more over all general consensus from all of you as to what you would use or would recommend for my application!

I recently sold my 04' Subaru Wrx that i fully built that got me an 11.7 in the 1/4 mile. I sold it to pick up something new that would be able to handle the abuse of drag racing every other weekend throughout the entire summer as the subaru just couldn't take that.

This winter i plan on fully building the motor and doing transmission and drive-train work. So here is my question to everyone:

I have a second car(2009 mazdaspeed3) but I plan on using the car as street drivable but with an emphasis on drag racing. I'd like to be able to drive it to and from the track.

I'll be running slicks, and don't have a problem with spraying either.
I have already purchased a 350 4 bolt main block.
Was looking at using a GM 400 crank but for drag racing applications i think i will be smarter to use forged like a scat
AFR Heads
TPIS or Headman Headers
Full 3 inch true dual exhaust cat-less(no inspections in SC)
Not sure on pistons or rods but i'm sure i will be smart again to use forged
and not sure on cam!
dana 44 rear end, not sure on what gear to use here
stall converter

My goal is to do an 11.5 in the 1/4 mile
I'm not looking to skimp here either, don't mistake me for someone who thinks he can to this for 2k or something i'm willing to spend the money necessary over the course of the winter and into the spring to do it right! I don't have 20k to just drop on it but i figured 6 - 8k would get me in the right realm. I am very mechanically inclined, been working on cars and pulling motors since i was a kid so all the labor will be done by myself and my old mechanic family friend . I also have a LARGE experience with porting and so i will be doing alot of that here as i see it helps!

Here's the slips from what the car ran stock last night!

3.75 or 3.875 stroke 195 afr comp head tpis 242 solid roller miniram intake you should get your 11.5 and be able to drive it about anywhere. COuld do it with a hydraulic roller too if thats your thing, just prefer solids for all out performance

Id use a little more gear, if you keep it a 350 go straight for the 4.09 gear, stroke the motor if you can so much easier to go fast and a lot more fun on the street.

 

3.75 or 3.875 stroke, this is determined by the length of the rods if I'm not mistaken?

And yeah i plan on doing the 383, i think it will fit my needs much better and like you said be a blast to drive on the street

 

Oh yes and i forgot to mention that i will be wanting to run E85!!

I ran this on by built wrx and had GREAT results with it. I know i will be needing a larger fuel pump, larger injectors, and a different fuel pressure regulator. If anyone has any experience with this also let me know!

 

Email (Brian) Bjankuski from this forum. He's got experience with E85 on his vette. You'll probably need to decide if you want to bump compression above the "normal" pump gas compression range. He'll be able to better advise on that.

You'll be stretching your budget. My guess is closer to 10k if your redoing a transmission and rear end.

 

Gottcha ok well i appreciate the info. I think with the help of my friend here i should be able to source parts at a good price. But if it does go to far I'll prob have to stick with pump gas. I'm unsure about weather or not i should raise compression, my friend(Brent) did mention that to me as an option but i don't know of the benefit if any yet.

I'll shoot him a message and see what he has to say! As far as the budget goes i am flexible. I'm not looking to rebuild the entire transmission, From what my friend told me he had his "strengthened" and a stall converter put in at 2800rpm for around $800 with me removing it obviously.

Thanks Greg

 

Good news!
CF member "NEAT" ran a 11.99 1/4 mile with a stock engine, tune, slicks & a 250 shot....so 11.4 might be doable with just a few more mods on top of those that Neat used.

 

Holy! thats AWESOME! was he running stock transmission and stock rear end?

 

Ask him - member profile page: http://forums.corvetteforum.com/members/20838-neat.html

 

spend the money on Dennys driveshafts if you keep the IRS.

 

Call me a rebel (and take what I say with a grain of salt as my mechanical ability is below yours) but while the 383 would be fun due to the torque on the street(and running slicks) its been done. If you were looking for somethin more unique a 355 and single t67 or bigger would certainly fit the bill. I would think that certainly be possible to run 1

 

Sorry phone cut me off. It should certainly run 11.5 on 93 octane. Dunno how important to you it is but its a combo that's a lot less common then just a 383.

 

Oh trust me i'm all about turbos and i agree with you, i do more outside the box kinda stuff. i'm not afraid to cut and weld. It's what i grew up on(i'm 23) so not long but still for the past few years i've done alot of my own tuning and fabrication with subarus running 21 to 25 psi. I just don't know about this game and adding a turbo. From the kits i see available it's pretty darn pricey. What kind of setup are you refering to? building the stock block with forged internals bored .030 - .060 over and then a turbo kit?

Here's a few pics of the car i just sold. had 371wheelhp and 344wheel tq AWD

 

First of all, please notice there is a FI/NOS section for C4's. Take a look around there to see if you can get a better idea on cost. If you're thinking about buying new stuff, I'm pretty sure it's pricey. Seems like it was $5k just for FI 4yrs ago. And, the few I saw installed on TPIs weren't exactly impressive. The cast pistons on an L98 aren't anything to write home about either. Boost is a route I decided to avoid -- but I was looking for my investment to last beyond 10k miles.

There are good (breathing) intakes to slap on an L98 and you could build it for FI. If you're doing to do both, you might as well shoot for 10's. NOS + gears is probably the best option if you want to avoid building a motor.

 

Yeah after thinking about it some more this evening i plan on just sticking with doing the original plan of doing a motor build. I really don't want to get involved in all of that. The 383 will let me reach my goal.

Let the thread continue on with info from the original post

 

383 sounds good, better intake, heads and with forged parts, and all good parts etc. should also be able to handle a 125-150shot if later desired. I'd stick with pump gas @11:1, a decent size bump stick....no baby cam.

A good d44, re-work the trans and a good converter should be part of building a total car. If staying with the stock short rear tire, and depending on other motor tweaks, I'd look at 3.45-3.73 gears. I wouldn't do denny half shafts, if it comes to needing better than the stock allum. w/good u joints, chrome molly shafts can be done quite a bit less and better IMO....

why would he build a car with drag racing in mind and use a "stock short rear tire" ? im build a street car ( cam ls1/t56... >400hp) and broke them playing around on the street with 335 kdw2 sweet tires. if you look into it, anyone with power usually breaks the half shafts. if he plans to spray the car, and spray it off the line, be prepared to replace driveshafts and wheel bearings often. its up to you. personally, i spent the money on the dennys driveshafts. apparently youve never held one in your hands, its a wicked product, came complete, bolted right in, i did not have to give any measurements, u joint sizes nothing. paid my tab and they were shipped, and shipped correctly. so far no track passes, but ive played harder on the street then when i broke the stockers, and they still look perfect.

 

He said IF he kept the stock tire size, and offered an alternative in shafts.

Anything that is going to run an 11.5 pretty much needs to be set up for drag it takes some doing to get that number and of course its never enough

 

You only got to 75mph in the 1/4 .... Did this vette have a V-6 transplant or something?

 

this was not 1/4, it's 1/8th!
