Quest for the tens. One move at a time... - 01/19/10 09:14 PM
Whats up fellas. Im sure im in the same boat as alot of yall. Very little $$ and I cant afford to make all the changes I neeed to so you make one change at a time. So you try to pick the right move when you do get some $. Like alot of street guys I want to see tens. So far my best is 11.49 @118mph with a 1.55 60ft. It's a 74 cuda with a basic 440, stock susp with 275 M/T street radials. 90/10's up front and clamped springs with snubber in rear. More info on motor. 446 with trw's, Indy Ez's stock port, Vict Int, 850 demon, Hughes solid flat 572/579 252/256 @50 cam, 3.91gears and TCI 3800 stall. Hooker Comp headers with 3' exhaust. I regret some things I've done and like some things as well. This spring I plan on making some more changes as i do every year. Just not sure whats next. Motor work, Susp upgrades, different Stall, head porting. Just cant afford to do it all yet. Am i running ok with what i got? seen guys with more run less and guys with less run faster. What would be my most benefecial move. Your
is appreciated here.

I'd be taking a long, hard look at the converter. I've never had much luck with TCI personally. Converters make or break combos and I believe a quality converter purpose built for your combo with more stall speed will pick your combo up.

I would look at head porting, before the convertor

I vote converter, first and foremost, too!
You don't have to spend a grand...if you want to keep the car streetable, call Dynamic (Frank Lupo) and order a 9.5" for your combo. I think they're around $600. Or watch for a used (from a trusted seller) 8" if more race only.

Snubber and converter in the trash.Call Kenny at PTC for a converter.A good port job.Should put it right in the 10s.

Im gonna borrow from the import guys on this one and say slap some stickers on it! Every import ive seen at a car show that had stickers on it the owner told me it ran 9s or 10s.
Cheap hp in my book!

I use to own a NHRA legal stocker that ran 11:20 at 119.MPH and change, it didn't have a adequate fuel delivery system on it to run any faster I found out after I sold it
My message is I also agree on getting a better converter. I was offered a TCI on a racer deal back then and had to have it modified by Munsinger several times before it work as well as a Turbo Action. Take the time to call several different GOOD conveter companys and tell them about your combination and see what they recommend. I will bet money that the Turbo Action will be better than most and as good as any of them
Your MPH is better than your ET and 60 ft. times, is the car spinning the tires now? If so fix that first before making any other changes

Right now your .3 slow based on the MPH, that would
suggest a chassis issue... but it could be a fuel issue
also if your running out on the top end... I would try
to find out whats wrong now

Re: Quest for the tens. One move at a time... - 01/20/10 04:11 AM
sounds like a street car.....I'll bet the converter is the one thing you can change and see big results. Is this a 10" converter...thats the biggest compromise in most street cars (mine included)?

Re: Quest for the tens. One move at a time... - 01/20/10 04:17 AM
My vote's for the converter. Get a 8" and you won't regret it.

Re: Quest for the tens. One move at a time... - 01/20/10 04:24 AM
Another converter vote here. And you DONT have to spend $1k on one. I bought a used TCT 9.5" for way less than that , and my car picked up 3 TENTHS--------on just the converter.
Call dynamic / Tct / PTC .
also what is your compression ratio?
those heads and that cam will definitely go 10's with the right combo.

We would make a good race as my best et in my 63 Sport Fury is 11.49 @ 116. I have a basic .030 over 440 (446) close to your build but I use 906 heads and the MP .557 cam. Funny as you have 2 more mph then me and a better 60 as my best is 1.57 yet I run as fast an et as you. I run a 9.5 Dynamic converter and love it in my street car. I drive it all the time as I drive it much more then I race it. Your car 60's good for mid 11's and actually should et better with 118 mph. I have to agree that a good converter may help if it is matched to your combo. I would call the converter company you use and let them match one to your combo. I use Luppo's Dynamic but there are alot of good one's out there like PTC , ATI , Turbo Action and so on as you should be able to hit 11.20's now with your mph. Good luck , Ron

not sure on the whole story--
sixpackgut may know

What's it run in the 1/8? If I were doing one thing it would be a good port job, then get a converter next year. I've had good luck with Edge Racing Converters, talk to Andre.

Im not sure bout weight. But I got a Glass hood with and alum radiator. I also removed power steering to save some weight. Im thinking bout 3500ish maybe.
Thanks for all the responses. The compr is 10.8 and the stall is a 10". My 1/8 is 7.32 @ 90mph (i think) not positive, im not at home and time slip is there. My fuel line is 3/8

you can try this I know other converter companise do this. let them know you purchased the converter thru them and its to tight, have them loosen it up a bunch thell them the specs get a price and weigh the cost of a new verse getting this one worked. then you may have enough left over to put some money into the heads or a gear swap. I suggest you run at least a 4.10 to 4.30. look on here for the parts most of the guys on here are truely honest about what they are selling. and if you need to ask about someone selling parts feel free. you will also find they guys on here are generally a very tight nit group. thats my

Finding out what it wants for a tuneup would be first in my book. If there is a very good chassis dyno and operater in the area, I would go there. Also, stuff like long collecters, cold air package, unstable timing, timing curve, cam installed centerline (maybe advance it?) and a bowl port and sharp valve job on the heads ( > $350? )to get the most out of it. If you have done the heads, great.
Try less lash, first on intake then exhaus. Watch the individual segments of the run, plus weather, to get accurate data.
Finally, the dyno will show if you need some jet changes, and if the air fuel ratio is right at all rpm ranges.

good luck asking a question like that cause you are going to get a thousand different answers. good luck on picking which one is right for you

I remember this well...I was chasing 10's along with Gary (UNLAWFL) in 2003...my big help was ATI 8" convert. and Cal Tracs with 4.10 I went from 1.58 60' to 1.45 best w/slicks. Call Cal tracs and get there 90/10 shocks ....and rancho 9way for rear ...my 2

Thanks for your
guys. The 850 demon is out of box. Timing is at 36. 3" exhaust with flowmasters super 40's turned down at axle. I have wondered bout the springs though. Im using the Indy springs that came on the heads. (supp to be good for .600 lift). Im at about 6200 rpm when crossing the stripe. I do have a set of 4.56's that i got a good deal on. Thaught bout using them but man thats low for a street car. Plus I feel they will put the rpm's too high at the line. Not sure if stock bottom end can handle that kind of R's for long. I agree that i need a chassis dyno to see what works or doesnt. Just dont know of one around here.

Converter needs to go for sure.
I had a TCI 10 inch that at the time performed OK. But looking back it had about 13 percent slip, which sucks, plain and simple.
In my car a TA tight 8 inch that flashes right under 5k was worth at least .17 over a very decent PTC that flashed at 4200. Both converters calculate to 8 percent slip.
Id bet you would pick up .2 and 2 MPH with a better converter.
As others have said there should be more in your combo, maybe 10s as it sits. 10s with a converter change and tuning.
I didnt read the whole thread, but did you have the seats reground on your heads or are they the Indy supplied valve job?

I have to go with the converter here.I run a SB in my 3420# Aspen and i have a TCS 8" that flashes at 5400.Back in the summer my ET/60' times were all over the place and i was told the converter is on it's way out.I was also told TCS was no longer in business and bought a Ultimate 8",shortly after i found TCS again alive and kicking and sent my converter back and they replaced the sprag.I wanted to try the Ultimate before anything else from everything i've heard about them.The Ultimate was waaay too tight and slowed my 60' from 1.47-1.66 and the ET went from 11.0 -11.9 so 3 passes is all i made.Put my TCS back in and my 60' was back to a new best of 1.41 and ET best of 10.76.Oh and i run with stock leafs with 1 extra leaf each side and pinion snubber as well.I'd like to try Cal Tracs but don't think i'd see any improvements and no one makes 90/10's for F-body cars.
Thats Great!
