Went racing with new eng.

[383man]

I snuck up Cecil County raceway Wednsday evening and got 2 passes on my new combo. Problem was I have an 850 DP on my 493 and it could use more. My first pass felt very lazy and was an 11.27 @ 113 as it was so lazy I lifted. Went back and took the 80's out of the primary side and put 86's in. Got one more pass 11.04 @ 121 but it stil felt lean at the top of the gears. I know it will go easy 10's when I jet the rest of the carb. Still I was happy with an 11.04 on the second pass on it and that driven the 90 mile round trip on pump gas thru a full exh system. Next time out I will be looking for 10.80's at least. Here is the basic combo"

493 (.030 over 440 with 4.15 crank)
Dished pistons for 10.6 comp with my Indy EZ heads.
Custom ground cam thats 264 & 270 @ .050 and .634 lift with my 1.6 rockers.
Indy dual plane intake and the 850 DP.

This is in my 3700 lb 63 with a 727 and a 9.5 Dynamic converter.
4.30's out back and I run 30 x 9 Hoosiers.

Its a real street car as I drive it everywhere including to the track.

Nice looking car, that's a good showing, very well done, especially for a regularly street driven car...

Well that was alright.I'd be happy with that too.Nice ride too.I'm a sucker for those older B-Bodies.

Sweet numbers, what kind of stall is 9.5 Dynamic converter? I need a converter....love that pic you mind if I post it on facebook?

11.04 on pump gas on a new build, pretty impressive. Is the 850 DP enough carb for your setup?

 

[moparpoor]

Nice ride it will rock when you put a large carb to suite its ability.Hell 11.04 out of the box is very impressive.Congrats on the new motor.

ron, wtg!!!
im betting 10's on your next pass. good weather is right around the corner.
glad to see shes running great!!

 

[383man]

Thanks for the kind replies. The 9.5 Dynamic converter will flash about 4200 and its the same one from the old combo. I would like to have a bigger carb then the 850 but for now thats all I have. I plan to jet the secondaries up a bit also before I go back as it was still holding back in the top of the gears. Please do use the pic on facebook as I dont mind at all. Ron
