1/4 mile ET guesses
I am guessing you're right. With the old combo I was at the top of 2nd crossing the traps, now I am at the bottom of 3rd. The best run was shifting at 5500. One run I tried running up to 6 grand in 2nd but it spuddered a little.
Does anyone else think I would benefit from less CFM? Couldn't I change the jets in my current AFB? It does smell a little rich.
Hopefully this little 318 won't be in the Dart much longer but if it is I would love to break into the 14s.
One thing I know is a mild 318 will never be a top end powerhouse....lol.
I hate to see you spend money on pieces that wont work with your upcoming engine, but at this point, I don't know if the're enough tweaks to take off 2 tenths.....
As far as the carb, I'd just play with what you have. "Green" has a point about the valve springs.....If you think it will still pull to 6k and you have a fairly low lift cam, you could probably shim the springs and get a few more rpm from them.
Other thoughts would be......
The mismatch between the intake ports on the Stealth and the stock head ports.
Opening the headers.
Front tire pressure up to 45ish....track only.
Best pump octane and bumping the timing a few degrees at a time.
If your ignition system is strong, good wires, powerful coil.....you can open the spark plug gaps .005/.010....At the track.
Taking out any easily removable weight.
Staging as shallow as possible.
Varying launch technique....meaning to try just off idle to flash the converter, and also, power braking as hard as possible. Some cars work better one way or the other.
I'm sure i'm forgetting some, but a few things to think about before spending on a cam, converter, etc.
