This past weekend I made three passes at Lebanon Valley Dragway in NY. I was disappointed with the ET's. I thought my car would be much faster than it is. Best time of 14.96@97mph. My car is a 1965 K-Code coupe.

.030 over 289cid (now 306cid)
.525 solid cam
1:6 roller rockers
ported factory hi-po heads
10.5:1 forged pistons
factory cobra aluminum intake
650 Holley dbl
top loader 4-speed
3.50:1 open differential
headers w/ 2.5" full exhaust
Flowmasters (Delta flow 50's)

So here is how it went. I got off the line each time without spinning the tires. The RPM's came up really slow through first gear. Once the RPM's were up the car pulled good through the rest of the gears and felt like a strong run. I have 235/60/15 street tires so I didn't do a burnout. I said all that to say...Help! I am looking for some advise on how to find some speed out of this thing. Any help would be much appreciated. My goal is to get this car into the twelves.

Thanks

If you want your car to run 12's, you're going to need either forced induction (supercharger or turbo) or a nitrous system. To put a little perspective on it, the '65 Shelby GT-350 w/ 3.89 rear end ran a 14.7 second 1/4 mile @ 90 mph.

the first thing i'd do is...

get a posi differential and 3.73 or 4.10's

that will get you little more but not in the 12's with your combo...

small shot n2o will get you real close....

OUCH!

My 66 K-code ran 14.6 with a stock bore, stock pistons, stock cam and dealer installed tri-power from the 60's. I ran at 450ft above sea level, hot summer day, over 85.

Cast iron manifolds, stock dual point ignition, Street Firestone tires, 4 spd and a 3.90 posi. I mean the car is the way you would buy it new in 1966, and then add tri-power. Pics in my profile.

If it's a genuine K engine and car...don't spray! Be a shame to trash a K code block.

I would say you need to get the timing curve right and get a smaller carb. You are over fueling that engine. No reason for a 650 dbl on a 289. Get a 600 vac. sec and properly jet it. Then a gear. Shelby under ride traction bars would help too! I do have those on.

You should have a 14.2 car there.

Have you joined the HiPo Mustang registry and tried asking over there? MoneyMaker (Alex) over there is a pro racer, he has the fastest stock block 289 in the world.
