As far as Dynamic goes we didn't worry about it too much seeing that its not a pump gas engine.

We may do some testing with some other fuels later that have proved themselves in the ATV world. But for now she just had to get running. Sunday was the last racing weekend before the SHOOTOUT.

Theres more weird stuff but this should get things rolling.

John. Congrats on a very stout engine. And the performance in the car simply validates those dyno numbers. Great job. Let’s hear more details on that combination when you get a chance.

Did a little testing at the Antique Drags yesterday with the new 343ci Y block. We got to test the car and some of our new parts. All and all it was pretty successful. The motor and the car worked really good for our first day out. The motor got on the dyno Friday morning and was broke in. The rockers were changed out to the new Mummert 1.7's and after lunch we flogged 9 pulls out of her before we yanked it and went and thrashed for another day and a half to make Sundays festivities.
The first 5 pulls were used up watching the jetting and and sneaking up on the rpm. We made a jetting change and set the timing to 35 degrees and pulled her 4 more times. 535hp@ 6800 and 460ftlbs @5300.
Specs on the motor to come.
We ran our best ET of 6.53 legging it out in second and our best MPH of 103.35 in 3rd. Gearing change was the first thing that came to mind.

Like all of these projects it was an up hill battle but seeing it go was worth it.

Hi Mark,

Drag racing 2 seat T birds almost always requires the Hard top in place or soft top up whereas when autocrossing it is not required, go figure. If you have a roll bar they might feel differently. The only exception was here at the local 1/8th mile track when I showed up without the top but with a helmet and whined piteously when tech tried to send me home for the top. They said never again without the top and T birds that race are so rare that they will remember.
