Hello, this is my first post on this site. I like what I see here. I would like to start by saying that I fully realize the only way to get your E.T. is to take the car to the track, which I fully intend to do. Stuff just keeps going wrong and the suspense is killing me (tranmission input shaft breakage, head gasket replacement, carb rebuild, and on and on). I have an estimated E.T. for this car, but what I was wondering if anyone knows any members of this board with a car similar to mine, and what kind of E.T.'s they run. The car is in my signature, but here are the details again:

1984 Camaro, 3/4 tube chassis with 10 pnt roll cage, all steel body and hood, all glass windows, 5 gallon fuel cell, 467 BBC with 12.5:1 CR, pocket ported GM iron 049 cylinder heads, 2.19/1.88 valves, single plane Weiand intake, 1050 Dominator carb, 1 7/8 Hookers, 0.595/0.595" lift 249/249 degress duration camshaft @ 0.050" lift, solid lift cam. Powerglide transmission with transbrake, 4200 stall, 9 inch Ford with 4.11 gears, 4 link rear suspension with double adjustable Strange coilover shocks, 31.50x14x15 rear slicks.

I also realize the 4.11's may be a little tall for this set up, and some 4.56's would definately be an improvement. I would guess this is about a 10.50 1/4 mile car. Any like E.T's, ideas, or suggestions? Thanks for any input guys and nice site!!!!!

Ya, probably somewhere in the mid 10's is about right.

i see ur form easley.sc i live rgt down the road in anderson. id like to look at u car sometime

AlkyIROC

I had a solid cam with .638 lift that ran into the 10's. Although that cam has moderate lift, duration is very small. Something closer to 260 @ .050 would be better.

Without knowing the race weight, a rough guess is only a rough guess. Seeing as it's all steel and glass, it's probably very heavy even with a back half. It's possible it will only run low 11's.

With the tall tire, 4.11 is a street gear. 4.56 minimum reqd. Really depends where the shift point is.

Camshaft looks like a 11-219-4. Power only peaks at 6500. Not a bad street cam but not the best choice for your combination. What fuel do you intend to use?

ezstriper

yes, and get rid of those 1 7/8 headers too small...

Stephen, thanks for the reply. The Black Pearl appears to be one mean ride. You are correct on the cam, it is a Comp 11-219-4. Right now the engine has a stock GM crank and rods, so I was trying to keep the RPM a shade below 7,000. Future plans (who knows when) include 4340 forged crank and H-beams, a longer cam to crank it up into the 7500 - 7800 RPM range, and probably a 5.13 gear. Maybe when I win Pinks All Out or the lottery!!!
I also run 110 in her. I'm not serious about the competition part (yet), so this is just something to have some fun in right now. What max RPM do you turn the 540?


Let me get her back together, I'm replacing head gaskets right now. The info bar said your from Toccoa. I grew up in Canon GA, near Royston and Carnesville, about 30 minutes from Toccoa.

I shift around 7000 and go through the traps around 7200.

he`s good, I went from the 1 7/8 hookers to ed quay 2 1/8`s...no change....that is on a 500 inch 14.1 motor too.

johnfwz28

yeah you're right MW66nova. everyone says thats really slow for the setup that i have.the problem was that it was our first time at the track with any car, let alone a back-halved race car. we(my son and i) had far too much air in the slicks,car was under tuned, and we just didn't know what we were doing. my son drove it. he got scared on the launch and lifted,but he quickly floored it again and ran a 7.65. the car is capable of quicker times i'm sure in the hands of a much more experienced driver. a friend of mine is going to the track with us next time. he will give us pointers. i know we will better times then.

what track u go to?

mw66nova

iTrader: (13)

sounds like you guys dove in above your heads...start slow and work your way up...

johnfwz28

we took the car to Commerce ga track.

not really. it's just a 383 stroked engine

i go there alot going next weekend

johnfwz28

i went there on a t&t nite, the tech guys gave me a hard time. i think i will go to the smaller track next time. you know Eatonton or Phenix city ala.

u want them to be hard on u for ur son safety. they dont pick on ppl if the stuff is safe.

johnfwz28

that's true. i can appreciate them doing their job, but they didn't have to be such ****** about it. i guess i shouldn't complain, they did let us run. i guess i didn't know that your seat harness has an expiration date, or your helmet has to have a certain letter on it, or the straps that hold your radiator in must be metal not plastic and so on.

hey by the way, where is Toccoa Ga.? is that far from Gwinnett county? i don't know if you saw my other posts, but i'm the guy asking about runner bolts. got any lying around?

mw66nova

iTrader: (13)

eh...i'd stay away from Eatonton...that track is SCARY...talk about door handle to door handle racing....

johnfwz28

i've been there a couple of times, but only as a spectator. we have never taken our car there. and you're right the cars are pretty close together.

mw66nova

iTrader: (13)

and they don't prep the track, and just allow the rubber to build up and ball up. it's nasty. we beat the main bearings out of a motor in my dad's racecar there a few years back due to nasty wheel hop/spin.

johnfwz28

so mw66nova do you only run at Commerce? if not where else do you go?

johnfwz28

hey stephen, this may seem like a stupid ? but what exactly is "the traps" that you go through at 7200 rpm's. (sorry, i'm new to racing at the track)

i go to Silver Dollar Raceway most times, but i've been all over the place. South Georgia Motorsports Park, Commerce, shoot, i've been to Maryland International Raceway with my own junk...but i've been to almost every major racetrack on the east coast, and midwest working with other cars.

-Moroso Motorsports Park in West Palm Beach
-Bradenton Raceway, Bradenton Florida
-US 41, Albany Georgia
-Memphis
-Bristol
-Phenix City
-Savannah Dragway
-Macon National Dragway, Twiggs County GA
-Virginia Motorsports Park
-Cecil County Dragway, Rising Sun MD
-Atco Raceway Park, Atco NJ
-Pittsburg Raceway, Pittsburg PA
-Norwalk Racway Park, Norwalk OH
-Morocco IN
-Great Lakes Drag-A-Way, WI
-Corodova International Racway, Cordova IL
-multiple places in Ontario
-many more places. i've been to all the premere tracks on the east coast, and ALOT of the not-so-premere places...so, i avoid Headhunter's in Eatonton at all costs, lol!

66 feet in front of the finish line is a timing light. When you cross the finish line, you trip the 1/4 mile timing light. The time it takes you to travel that last 66 feet is the MPH traps. Your 1/4 mile MPH is a calculation. A time slip MPH will never be as accurate as something like an in car accelerometer. Cars like mine don't accelerate very much in that last 66 feet so the MPH is almost constant for that short distance.

okay. here's a different question. do i have to go back to "new post" every time in order to see your replies while we're talking back and forth? or should i just wait right here on this thread?
----------
okay, thanks for explaining that. i really didn't know that.

johnfwz28

stephen, how many passes do you make using the same plugs? what octain gas do you use in your racecar? i'm using 114

Why dont you guy's let him get his car to the track before he starts to rebuild it. I'm sure he can improve but you won't know that by benchracing. I also think he has bugs to work out before he needs cam or headers. Part of the fun is sorting your car out .
