New track times...still not happy

[6T9PONY]

I have a few questions....

How much does the car weigh?

What is the main purpose of the car? Mainly street and a little strip, or the other way around?

At what RPM do you shift?

What is your actual stall speed? Are you getting up to the advertised 2500 RPM before you start to spin the rear tires or do they start to spin at like 2000 RPM? I have a TCI Breakaway in my C4 and it's advertised around 2400 RPM but I don't see it. My tires will start to break loose at about 2000.

How are your launches? Are you spinning, bogging, getting wheel hop, etc.?

How well is your 351 tuned?

I don't really know enough about your car to have any ideas right now...these questions will help. Hopefully they'll help other people, also.

I probably have the same converter you have then. No..I don't see 2400 stall either...it's more like 2000
My friends said I wasn't spinning and I couldn't feel if it bogged or not. My friends, who was watching, said I didn't bog either.
It was a day/night difference over the street tires though.
My weight is around 3200(never weighed it). 82 GT's aren't very heavy.
As far as tuning, it's pretty much "out of the box". I didn't mess with timing or jetting or anything like that......yet.
This car is a street/strip car too.
JESTER, I have a 351w so no, they are not E7 heads but they are ported & polished 351w heads with 1.94/1.60 valves.

You'd be able to tell if it bogged--more so than your friend watching you from the bleachers, anyways. It didn't sputter and fall on its face for a second or two when you mashed on the throttle, did it?

You definitely need a higher stall converter. Put a tranny cooler on there if you don't have one installed already and get a 3000-3500 stall converter. It'll be kind of a pain to get used to on the street but you'll love it at the track. With your current combo I really don't think there's a whole lot more potential, though. With a stall and maybe a little tuning I can see you going 13 flat, but 12s might be a long shot.

Your heads are a bit of a bottleneck, but you're just going to need some more fuel, man. With that cam you're going to need to get a decent amount of fuel in there and that 625 is probably not quite enough.

One more thing, what is the elevation of the track where you ran?

Jester,
I am not sure I know what the carter adapter plate is referring too. Is this similar to the spacers used? I thought those were considered to be a performance add on.

As far as the T.C. I have never had a TCI, but the B&M I had did not come closs to it's advertised stall. I think if you went with a better maker of T.C.'s, you would see better gains, especially with the slicks.

Carb SPACERS help out alot, running one myself. I'm not familiar with the carter carbs, and was just concerned that it had the same bore spacing and bolt pattern that the Holleys do. Picture trying to put a dominator on a "normal" manifold, you'll need an adapter plate and that creates a HUGE bottleneck. So, I was just making sure the carter bolted right on to the intake.

now I understand

I have a carb spacer but it has an open plenum. I'm being told on a different board, that my engine is running strong after the 1/8 mile based on the track time I posted above.
What "should" my 60' be with slicks....1.7's??
I also need to figure out what my advance is in the dizzy and how much total advance I have in by 3000rpm
I'm going to tune the dizzy and accelerator pump on the Carter and than see where I'm at and go from there.
A friend of mine will be selling a weiand stealth intake and a Holley 750 soon and I'll try those then.
The converter is going to have to wait until later.

My set up went 12.93@105 with 1.74 60ft. I need to buy adjustable control arms so I can play with the pinion angle to keep the weight transferred to the rear wheels. My car would hook hard then 100ft out blow the tires off shift into second early everytime bogging the motor down. My head and intake are untouched. My cam is very small. I have 9:5:1 compression. With your combo you should be in the 12's. One thing I would change is that 625 carb.
