Hi, gotta update this here.....

after changing to 1.6 Rockers (Mancini / HS bodies) this winter and putting on new calipers, i did some testing this last weekend at the first Drag event here. After some 11.7 passes (i did not expect that much difference) i got a new PB: 11.61 @ 115.1 mph, 1.67 60ft. I´m pretty happy!!!

So i think the engine want´s more cam. We´ll see what´s going on this year, if i can save enough money i´ll upgrade the cylinder heads and the cam next winter, maybe the intake, too.

And I will change from the 727 to 904, that´s for sure (already have a good core to rebuild). A custom converter will find it´s way in the car then, too.

I had a great weekend!

Michael

Hi,

i´m pretty excited, was at the drags this weekend, after some low 12 sec. passes i finally got an 11.98 @ 113.5 mph. 68 Valiant 2dr Sedan, full interior, 408 cui with Indy X-heads, Comp XR286HR cam, EDE Performer RPM, 750 Holley HP DP (AED). I recently did the trans and put in a 3500 stall converter (Turbo Action 17805st).

Now i have to repair the left front caliper, it´s sticking and i think i left some time there. Will try some 1.6 Rockers in near future. I´m positive that there´s more in it, best 60ft. time was 1.79, i think there´s also room for improvement.

Michael

p.s.: the pic is from last year....racing my swiss buddy Marc. He´s a nice guy with a cool 318 on juice, also in the eleventies.....
