Well took the wife’s car to the long track and it did very well. This is the one we have been doing all the work to. We did the new front clip and made the old 355 a 383.

The motor:

383 (stock 350 block)
Ohio crank shaft: rods & crank
Mahle pistons 10.5 to 1
Small Roller cam .512 /.534
TH350 with a summit converter “2500 stall”
491 GM Heads
650 Demon
RPM Air gap intake
3:55 Gears
Car shifts at 5000 /4200 in drive
Weight: 3060 with her in it
Full steel body with all the interior

11.89 at 112 mph

Old Motor went 12.72

Not bad for a fun little street car

Not bad at all! :clap::clap::) Your combo is very similar to mine, except probably 200 lbs lighter. I'll be running the 1/4 for the first time this weekend and would love to get into the 11s.:D My best 1/8 et is 7.80, so I have some tuning to do to make it. What jets are you running?

What ever BG puts in the 650 DP. It's lean I do know that, also timing is set at 16 in totaling out at 38 with it all in by 2200.

You should be able to hit the 11's I think if it will hook.

Her car will do this with no burn out that's the cool part :D

Sounds pretty close to my car too.
We had great air here yesterday.
Mine went 11.90 in the first round hard on the brakes and I ran out.]
Oh well.
My cam is a .520/.540 roller also in a 10.5 cr 383.
