I have bit off more than I can chew. One of my friends challenged me to produce an Fbody that will run low 11s on the motor alone.

He has a turbo mustang and runs mid 11s and doesn't believe its possible for an Fbody to run very low 11s on the motor alone. We made a high dollar bet so now I have to put up or shut up.

I have the cash and I've already started buying mods.

Hooker LTs
CAI
1.6 RR
True Dual Exhaust
52mm TB
3200 stall Vigilante
Mustang 8.8 rearend conversion with 3.70 gears
ET streets
Bare LT1 block bored for a 383 application

What else would I need?

Do I have to go solid lifter or can I stay with a hydraulic cam?

Crank? Pistons?

I might use nitrous later to get into the very low 10s.

 

a nice cam and heads coupled with all that could probably get you there
depending on if you have emissions, and if you get the cam grinded to your heads flow numbers

 

how much is the bet?
you might be better off just losing the bet instead of spending all this money on mods
but then again, you wouldnt be able to say 'i run low 11's n/a'

 

I was planning on making the car a high 11 sec car anyways.

I know how to make it run high 11s. Thats not that hard with a 383 and stock ported LT1 heads and an XE cam.

But I need to run low 11s now.

The bet is more money than what a regular 383 longblock would cost.

 

If you want 11's or mod 11's either Make sure you put that other half into your suspension and Chassy. ...and I hope you have a 12 bolt already. IF your running Big *** Drags and plan on making that much HP either get the 12bolt or alteast a Triple AAA card so you can get a Tow home after your rear end brakes... This guy better have bet you 10K and have it. It's going to be very expensive.

 

build a resleevd 406 lt1. Keep compression around 11.5-1

 

Yes I realize. Thats why I converted my rear to a Mustang 8.8 rear with the stock 10 bolt tubes and Moser 33 spline axles.

 

You know, you could do it on a h/c car honeslty, just set it up right. Lower the weight, right suspension, match it up to the right size tire and have a good suspension in it to hook it all up.

Look at Steve Stumpf, Ken Anderson, Frank B, the guy with the red 95 355 Formula. All those cars arent high dollar builds, but they all know drag racing and they know how to make a car run down the track with what its got.

You can look at it to ways, you can make a little run alot, with car thats just set up right, plain and simple. Or you can dump a ton of money in to a stroker, and this and that and spin its way to 11s.

But low 11s just means getting the car set up right and sixty foot like a ****. You can do it on a good heads and cam car. If you think you need some high power monster, go look at FrankB's 11.40@115, 340rwhp, A4 95 Z28.

Haha, plumb up some N20 invisibly and purge it under the car just incase you build this thing and the first time it runs high 11s you can turn that on and make some money.

 

Are AFR heads within your range? Some ported 190cc heads would do pretty good with a 383. If money is no object you could go with AFR LT4 227cc heads or maybe even some Arao 32 valve heads. Both requiring modifying the intake. The araos need the block clearanced for the pushrods and also custom headers. Youd probably need a 396 or 409 for all that flow. Alot of work but Id think low 11's would be easily accomplished with 500-600rwhp

 

i think he said he needed to run off the MOTOR alone, which means no nitrous, no SC, no TC, no 383 if im correct...
but since he is using a TC, **** jsut freaking go throw on a Twin Turbo kit on that LT1 and a turbo cam then fore sure you will BLOW his DOORS off along with the money landing right in your hands...turbo will cost wuite a bit of money, but hey that should put you in the 10's, youll also need a goo read end and some TRACTION big time...TUB that car, then youll have some traction...
lol
randy
and let us know who wins....good luck

 

I can run a stroker. Just can't run a power adder like turbos, blower, or N2O.

AFR heads are in my price range. Would I be able to do it with the LT1s or would I have to go LT4s? If I went AFR LT4s would I have to get an LT4 intake?

 

**** man, what ISNT in your price range. If money is not an issue then you wont have trouble hitting low 10s NA.

 

You don't need AFRs...stock ported heads will be fine.

Get a decent bottom end built. All your other components are looking all right.

For Heads and Cam, talk to Advanced Induction, they seem to be having a lot of success by properly matching heads and cam together, instead of slapping something together like most people do. Have them port your heads, then have them make a custom grind cam to match your heads. Then as far as the engine all you will need is a good dyno tune.

Aside from engine, like many have said, suspension is key. Control Arms, Panhard Rod, Torque Arm are musts. Slicks and Skinnys, and weight reduction (take out bumper supports, back seat, spare and jack, if it's in your price range, do a tubular k-member and a-arms, take out AC, take out washer fluid tank, or drain it)

There are so many 383 cars running low 12s it is rediculous. If you can't make a 383 run high-mid 11s at the minimum you didn't do a good job of mathing your components together. So many people just grab whatever they find and put it together and expect it to fly, but then it doesn't. Do yourself a favor and match up everything...you can make it run what you want. Maybe not by spring, as you will need some time to dial the car in, but by the end of the year I see no reason why you couldn't reash your goal.

I would seriously consider a 396 to get your 60fts down with all that torque. Defintely match the cam to the sweetass heads you will have/need. Some bigger gears wouldnt hurt if this is a strip only car, stall seems to be good for a 396 with a mild cam.
