Okay, gotcha.

Went to first Test & Tune of the season, ran the Camaro with mods for the first time (for reference, ran a 17.75 completely stock, bad fuel pump; 17.35 stock w/good fuel pump, 16.85 best before mods - 17.0 was very typical).

First the excuses:
Tranny - something screwy, won't shift from 2-3 at WOT. So, ran in "Powerglide mode" - going through the traps in 2nd at 6200 RPM (power left at 5800).
Conditions - warm, headwind.
Tuning - nothing special done (remember, this is a daily driver, running on my every-day tires, etc.). Plugged air cleaner thermovac, adjusted tire pressure. Emptied trunk (3510 lbs w/driver & 3/4 tank regular unleaded).

With 1500 launch stall, shift at 6000, results were:
60' ... 2.437
330' .. 6.761
1/8 ... 10.272
MPH ... 70.33
1000 .. 13.261
1/4 ... 15.772 (sea level corrected 14.63)
MPH ... 90.10 (sea level corrected 97.06)

From the speed, obviously the power is there. From the 60', obviously the gears aren't (hooked up fine, though). Oh, well, better than CHP Mag's non-gear, non-sprayed attempts with My Generation Camaro.

In answer to an old question, no, it isn't faster than the '57, but it'd be closer if the tranny did it's thing right. With gears and traction, probably faster (of course, with gears and traction, the '57 would be faster, too).

Now, gotta get that tranny up to snuff, and try again...

 

Nice results, I'm having a similar problem though with my 1-2 shift, I've found if you let off the gas mostly then shift and push right back on the as the shift will be firmer, maybe that's something to try utnil it gets fixed.

 

You have the 2-3 shift blues too huh? If I ever figure out what my problem is I'll let you know. Last time I took the car to the track it did that and I ran a 15.9@78 or something stupid like that, basically stuck it in drive and just cruised the rest of the way down the track.

Nice run anyway.

 

many have done that. it's a problem the earlier models had with the valve body when they get hot. i'd recomend trying to use a newer valve body on it if you can find one or install a trans go kit. seems to fix that. a large cooler helps too.

 

I think there's something binding in the valve body causing this, but note in the sig I've already done the Transgo shift kit. Also, it was hardly hot - when I made my first run, it had been two hours since I had driven it (a bunch of people out there for T&T).

Letting off and shifting is fine on the street, but it still takes a couple of seconds to actually shift. Doing that on the track would kill ET & speed.

If it doesn't get to working right, gears would be out of the question - can't go through the traps in 2nd when you hit redline at 1000' or sooner.

 

Mine actually has a newer valve body, tranny guy put it in there. And my car had been sitting a while too, I doubt it was hot. Seems to be a WOT thing only, and only the 2-3. Also has a Trans-doesnt-Go-into-3rd kit in it. Maybe I need to remove that thing and try again.

Trans-Go related problem? You know now that I stand back and look at it... I think I am gonna yank that kit.

 

I was actually able to knock off about .2 by letting off the gas, that's how bad my slippage is, this is using a G-Tech by the way.

 

Should have said, it was doing it (no 2-3 shift at WOT) before the shift kit install.

Of course, I never knew of this before the mods, because the valves would float at 5200 RPMs (and the race was over by that time in 2nd). The first time it happened, I was taking my 5.0 buddy for a ride soon after the mods - when the tach hit 6300 and I was already in OD, I finally backed off - wasn't that long of an on-ramp, anyway...

 

Mid-14s sounds like an excellent start to me! Especially with those 2.93 gears of yours. Actually makes me feel not too bad about my 2.73s

I think your car is gonna be low 14s before very long, once you sort out the tranny.

I've been waiting for your post, you know.

 

Yeah, I remembered.

For reference, I also ran the '57 yesterday after taking the Camaro home. It ran a 15.52 @ 92, so the Camaro is 1/4 second & 2 mph away from it. Need to concentrate on getting a few things done on it now (racing season starts in 2 weeks).

 

I got the scary 2-3 miss too. I looked up the problem. Turns out, the 3-4 clutch pack (yeah, wierd huh) is what is causing the miss. I saw it on http://sethirdgen.org/tranny.htm. It is a common, annoying failure of these trannies. Especially when racing and on on-ramps.

 

The link didn't work. Could you expound on this problem? Is it a worn out 3-4 clutch pack, or what?

I also have a 1-2 & 2-3 wierdness that appeared after the shift kit, so I was going to pull the VB back down to see if I could figure that out. But, if there's a clutch pack problem that needs to be addressed, I'll let my tranny man handle both (I have my limitations).

 

If its a 3 & 4th clutch pack problem is there a way to maybe make the clutches & steels have a very close clearance? What I mean is If there is very little space in between it just has to grab harder.

 

Went a 14.8 with a cat back and 3.42 gears, 15.1 with out the gears.

Went 13.8 @ 107 with the following:

170k 305 shortblock

rebuilt stock heads, 1.84/1.40 valves, no porting, slightly decked, new springs.

crane compucam 2030

edlebrock 1 5/8 tes headers, into an 3inch hiflo cat, and slp 3" cat back.

edlebrock performer intake

1 inch carb spacer with a holley 670 street avenger on top (did some jetting with it)

WC t-5

3inch DS

3.42 rear

fiberglass hood(had that on the car from when i bought it)

245/50/16 bfg gforce kdw

custom cowl induction setup

Car didnt hook at all, was runnin 2.35 60' s all day long... ran several 13.9's at a slightly higher trap speed.

Gonna be slappin it on the dyno and tuning the carb, going up for one more run ont he stock heads and semi wimpy cam, gonna throw some vortecs on it, air gap manifold, and a bigger cam and see where i end up. If someone has a suggestion on a cam, lemme know, email me it- i'm trying to work out what would be the best combo...

i didn't catch the transgo part. i'm too lazy to read that part when someone has that much in their sig. i assumed you might but figured it'd be usefull info anyway. i agree with the 3-4 clutch pack problem, it's just nice if you have more pressure. increasing the pressure can help, but not cure the issue of 3-4 clutches. the older 700r4's have valve body problems in this area though which can cause the same thing.

 

Considering tranny and gears the corrected trap
speed is very good. Puts the CHP 305 project to
shame......
You have a lot of potential in the ET department
when you get the launch straightened out. We will
be watching for updates....

 

Okay, let's all chant together now...

"Higher Stall - Higher Stall - Higher Stall"

You'll really expose the weakness of the tires then.

Nice runs - for a "POS 305"... We all know Smitty can't run worth a crap, either. After all, it's ONLY a 305. (Looks like you've proven your point.)

 

305's arent that bad. hell mine runs friggin hard. And i havent even done anything with the heads! we'll see, i might pick up some vortecs or just dump it for a 350... dollar for dollar the 350 will put out more than the 305, its just so nice sometimes when you slaughter a mustang, to tell em, nope, its only a 305 lol

Steve

 

I tried one run with 2000 launch stall - chirped the tires (just a little chirp), 60' worse, whole run worse. It actually felt very good launching at 1500. I think it really needs gears more than higher stall.

For now, it'll have to stay a driver until I can drop the tranny and get it freshened up. The '57 gets the 1320 duties until then.

I realize HP/$'s, 350's come out ahead on the dyno. I maintain, though, that I couldn't have put a 350 in for the money I spent (~$2k) and have it run as well as it does - because everything I spent would have had to have been spent on a 350, plus the cost of the 350 and possible rebuild. Had I touched the shortblock, then the tables turn.

 

Yeah def, right now, i am in about 500 bucks in mods to the 305, and if i were to yank it, i doubt i would put another one in. we'll see tho, there might be a procharged 305 coming to CT sometime in the near future... depends if i wanna stay in debt or not.

Smitty have a site or atleast is there pics of the car the 305 is in. I cant seem to find any. Thanks
