Art, thanks for not taking offence at my question. It was asked only to learn from folks that have been doing this for a lot longer than me. Your car ran VERY well in street trim.

As far as my efforts. I'm running a Buick V6 with a 4 barrel carb. Its the race version of the Street Grand National motor. We dyno'd the motor at 473HP at 7600RPM. Its very streetable but certainly doesn't have the low end torque of a big V8. Max torque was 390ft/lbs with 11.5 compression.

Since I started this project I kept trying to figure out why most Cobra's I see don't seem to run as fast as they should. Weight vs HP. As an old drag racer you know there isn't any magic to any of this stuff. Its HP/Weight/launch that count. Needless to say combination plays a huge role also. ie making all the parts work together.

We just started trying to get the combo on my car straightened out. I believe that the best the car will ever do is probably 10.50's or so. The 60' time of 1.48 can be improved with bigger tires. Currently I'm running Mickey Thompson ET STREETs which are 26x8x15. I'm going to go to 28x10's next time we go.

Any pointers or ideas from either of you would be greatly appreciated. The car has a Tremec 5 speed with a very tall Overdrive. Because of that I switched from 3.50 gear in the Ford 9" to 4.10's. They made a tremendous difference in the overall feel of the car. The little 274" motor "loves" the deeper gears. The 28" tires will mitigate them slightly but the improved traction will get the 60' times, hopefully, down to 1.30's. Or at least that's the plan. The car also needs to be able to Road race and autocross so I use 17" wheels and tires for that. Also I can only run DOT tires hence the Et Streets and not regular slicks.

I also use the MSD 6al ignition but my MSD distributor has an operational centrifigal advance/ no vacuum as I don't think this motor has enough to make it worth while.

As far as fuel goes I run street 93 octane with 10% toulene mix which gives me a true 97-98 octane which is plenty for the compression I have. At the drags I just put about 5 gallons of 116 on top of the street gas.

Lets see what else...Shift like comes on at 7400 with the rev limiter set at 8200 which is very safe for this motor.

As I said I'd like to compare notes with you guys to try and not make mistakes that others may have the answers to. That's what I really like about this forum. There is so much talent out there to learn from.

I've included a picture of the motor so you see the "mini" motor.

OOPS: the upload didn't work so go to "View my Photo Gallery" on the left side of the page and you'll see them there.

Regards to you both,
