Good air/good launch=another 3rd gen in the 12's
Well finally got there but in a very damatic way. Great air but really cold which means everyone is having traction problems.
Ran a couple of 13.30s being conservative at the line(2.1-2.0's
60fts). Stepped up the launch and ran 13.10 a personnel best.
Last shot with a good burnout and cut a 1.79 60ft and went
12.88 at 104.45 ! 20 mph headwind knocked the trap down,
should have been 106 considering the 1/8 mile ET and speed.
Run data:
60ft --- 1.79
330 --- 5.27
1/8 --- 8.20
MPH ---- 83.93
1000 --- 10.73
1/4 ---- 12.88
MPH ---- 104.45
My question is how much farther can you go and still maintain
good streetability. This car now is very tame with untouched
World S/R Torquers, .467/ 222 cam, low profile ZZ4 mainifold,
CC Qjet, and old, < 1.5 inch Edelbrock headers. Seems like to
get into the low 12's a 350 is going to have to be pretty radical
or will have to go to 383 or 400 cubes. Anyway is was a great
end to the season.......

Good times...I have the same heads but with smaller valves and was looking to do a cam change...might have to consider the one your running. Doing a little mild porting on those heads could free up .3 tenths easily if you know what your doing.
Thats a great time for your relatively mild combo....what tires are you running and how much you think your car weights?
Also noticed you are from NY, which track u go to?

Looks like your combination is working well.
Unfortunatly most further power mods like a bigger camshaft
will reduce driveability to one degree or another.
You've seen first had the benefit of cold air.
Consider building a cold air/ ram air setup.
Other "free power mods that don't affect drivability can trim the times a bit.
They all add up. a 10th her and a half a 10th there and pretty soon your running low 12's with the same basic motor.
A moderate Nitrous System will chop off about a second off the ets with good reliability and safty. An honsest 150hp gain is
a good goal. Be sure to use a dedicated system fuel pump and fuel line from tank to plate for the NOS. Don't try to piggy back it with the carb.
This route will give you the most bang for the buck without
the drivability issues.

Allgo, I run BFG drag radials 225-50-15 which are only 24" tall
but give the correct overall gearing. I think the car is pretty light
since it is an 84 with no air, no t-tops, std transmission. Since it
is a street car all weight reduction is just take out like seats,
jack, spare, front sway bar. I think it would weigh in around 3100.
I run at Lebanon Valley which is a great little track except for the
fact it sits at 700 ft elevation. Thats why I limit my running only
in the spring and late fall. Although that doesn't sound that high,
in the summer with the Hudson Valley heat and humidity the density altitude runs 2-3 tenths off.

excellent times, man. gret 60ft times. traction makes all the difference in the world. congrats on the 12 sec slip.
if your car is not lowered, i would suggest getting some hedman longtubes...they will boost power a little over the edlbrocks as they the hedmans have 1 5/8 primaries and they hang no lower than the oil pan.

You run at Lebanon, nice. I might have to meet you up there sometime next year for a grudge run... right now you would take me pretty easily, 13.0 for me to your 12.8, but come next season I should be better competition! All in fun that is....
PM me if you are interested, if not, great times, and good luck on low 12s!

My car runs 11.27 and is still a charm to drive, Of course that has alot to do with me prom tuning but none the less very,very , very streetable. Idles well @ 800 RPM, starts great all weather, still knocks down 19 mpg, comforting exhaust note ect,ect.
Those times are all motor to.

87TA, if I could do it over again I would start with a 406 shortblock which could then handle a larger cam and still maintain
decent street manners. You combo sounds like an ideal street/
strip choice.
25th, our race would be a classic Ford/ Chevy confrontation but
you would probably have the edge since my reaction time is
usually in the 1.0 second range. I am usually concentrating
on just getting the car launched since I only go to the strip two
or three times a season.
I guess my choice for the next mods would be a little pocket
porting, 1.6 rocker arms with new valve springs.....

I dont know how good my RTs would be, I run a pro tree all the time and I am not used to the full tree! My best full tree RT was a .501 and I have lots of mid .5xxs, but that was over a year ago!
Either way, I wouldnt mind a run for fun!

Here is a guy that runs a similair combo.

I vote more cam, and it seems that the Performer RPM intake is the hot ticket these days at the track and in the magazines as well.
Here is a guy that runs a similair combo.
Vinnie Coppeto
City: Fullerton, CA
Engine: 350
Transmission: 4 Speed
Year: 1969
Body_Style: Camaro
Combination:
Up to this point, all the engines I had built were for racing only. This was my first street/strip motor and my main concerns were drivability and cost .... 030 over 2 bolt block, KB 9.5 Pistons, Cast Crank, Solid Cam 230/240 @ 0.50, .498/.503 Lift @ 107D Lobe Center, Cam installed 3 Deg. Advanced, 1.5 Rollers, Out of the box world S/R Tourquer heads (2.02/1.60), Perf. RPM Intake w/Barry Grant Sports Claw 750 (now known as "Demon") Carb, HEI ign w/30 deg. all in by 2500 RPM.
Total cost including block ...... $2700.
Dyno'd @ 452 HP @ 6100 RPM. In 69 Camaro w/3.73, at 1000 Ft. altitude, 11.80's @ 117. All day long! Driven 55 miles round trip to work 5 days a week for 8 months. Driven to and from track ... "You don't need cubic money." I've been doing this a long time and it bugs me that alot of young guys are talked into spending more than they have, to go fast. Bitchen rods don't make H.P. Steel cranks are made to survive at high RPM. Make torque! The horsepower will follow, AND the engine will survive .... Great Combo - Try It!
