Naturally aspirated 10's on the street?

Okay, I know this is possible (points towards PINKY), but, how can it be done?

In others words can I have some specs on your car when you raced it, John? And does anyone else have a Mav/Comet that can runs 10's on the street without power adders? I hope this can be done with an 84' short block 347.

 

my friend has a 65 mustang that runs 10.30s with a 11:1 n/a 331ci on the street afr 205 heads and a big roller cam gets it done

Well it'll be pretty peppy with the 4:88 gear it's got, right now it's got a 10.5:1 compression ratio.

 

10's really ain't that hard. Just doing some research and building smart, not cheap. error on the side of overkill.

1) The biggest thing that I believe kept my car out of the 9's was headers. Running bent up 1 5/8 primaries was killing my times. Spend the money for some 1 3/4 or 1 7/8. Big power can be gained/lost with headers.
2) selecting the right gear ratio. I have had 4.88/4.56/4.11 gears in mine. The 4.56's were in it when I ran the 1/4 mile and it was taching at 7,500 rpm through the lights with a 28 inch tire and a (good) loose convertor.
3) convertor choose wisely based on combo.
4) weight its said that losing weight is cheap speed. IMO this is true to a point, then losing weight can get expensive and it can take away from street comfort. When my car was running 10.45's it weighed in at a little under 2900 pounds with me in it.
5) stroker kit I have an EAGLE 347 kit in my car. No replacement for displacement
6) heads AFR205. IMO this is wasted on a 347. If I had it to do again I would get the 185's. Now if I ever build a W stroker, the 205's will be the ticket.

Other than whats already been stated. It takes test & tune. The passes after the motor was broke in and the tranny rebuilt (couldn't handle the ponies and thats another issue) first night it ran 7.0's (1/8th mile) and I thought "well thats my hurdle" getting in the 6's. The next week I went it ran 6.90's. The next week I went with Ward Frahler and it ran 6.60's. Then the next week it went 6.50's and that is where it settled. I really never tried to go any faster. I just kept that tune for the next couple years. You would be surprised how much et you can pick up just my getting better as a driver. I really believe the last couple tenths I gained was all me, consistant burnout routine, hitting maximum shift points, figuring out launch RPM's, optimum tire pressure, keeping the car as straight as possible going down the track, staging correctly.
Lots of guys on this board that have seen the 10's in their maverick and I am sure they know what helped get them in the 10's.
There is so many places to gain et that 10's are easy

 

Well, I really am not looking for total performance I want a car that I have some bragging rights with, that I can race, let's say every other weekend, and then tow home, swap tires/wheels and drive on the street, it came with new slicks, and I just got a pair of rear sportsmans for the street. I was thinking, Slicks and supertricks for the track and Monocouqe wheels and sportsmans for the street. I don't plan to cruise woodward with it, but something smaller like the Telegraph cruise would work. Also I need a trailer, and to set up a hitch on the 72' truck, that would be cool to have at the dream cruise. Talk about nostalgia, a 72' F-100 towing a 70' Ex-super stocker Maverick. okay now I'm off topic, but in the 10.50's or lower would be fine for me. Thanks for the help too.

 

my question to you really fast guys who drive on the street is about conveterers.
what type of stall speed do you run?
are you able to cruise it with out the tranny geting to hot?
what size conveter are you using?

and some motor questions?
is any body doing it on a 302?
are you guys using light weight cranks, rods, and pistons?

 

My car runs in the 10's. It's very streetable with only 10.5 compression. And it's just a 331. I would be careful with the header selection if you're going with the 302 block. Bigger is not always better unless you have a power adder or some extremely high rpm's. I run 1 5/8" hookers. Also do your homework on the converter and gear. Call ATI or Neal Chance.

 

I absolutely agree ......and with my old set-up
13 to 1 spinning over 7 grand religiously, the bigger headers would have made a world of difference.

This is definitely not a "cookie cutter" project. Different needs for different folks......the key to any build IMO is knowing what you want and knowing how to get there by research, research and more research

 

Okay so it looks like the top 3 things I'll need is ....

1. Aluminum heads (not overkill though)

2. Headers (1 3/4 or 1 7/8)

3. custom convertor

I think that's all I need

BTW, what cams are you guys using?

Do you think iron 190 heads would cut it?

 

You shouldn't run 10's on the street, only the drag strip. But, good luck on your quest for 10's.

 

No, not street racing, just something I can race with and runs 10's on the track with and drive on the street to fool around with sometimes.

 

jmgford, which 1 of those cams do you exactly have? There's 4 or 5 on that site.

 

Love the looks of that stang got anymore pics or video?

 

I hope to be in the 10's this summer with my street car but i dont know. I do know if i had to do it again id do it different and id bet it would go faster.

 

Okay, thanks for the info, hope I'll have 'er in the 10's this summer.
