318 build-up has some track time.

[jkailholz@aol.com]

Here is what I put together with some suggestions from this board.

1971 Dart , original 6 cylinder car, gone with the 6 and in with the
1976 - 318 with 50,000 miles from junkyard. Junkyard transmission with 6 cylinder convertor. I put the kill your compression 360 heads on it with 2.02 & 1.60 valves. I think they were the 915 or 587 castings. I ported and polished the heads myself. Gasket matched the intake as well. Intake is a Performer. Plan on removing alot of material to match the heads if you use a performer. An Edelbrock 750cfm carb. I didn't have anything smaller. Hooker headers with 2 1/4 dual exhaust with turbo mufflers. General Kinetics 268 hydraulic camshaft. Lift is 454 on both and I think the duration at .050 is 216 or 218. Electronic ignition with light weight springs. Stock 7 1/4 rear axle with 2.76 gears.
I know this is not the best combination of parts , but it does work pretty good for what it is. This was a budget project and I picked up parts cheap.
Here are my ET'S:
1) 16.17 at 89.15MPH- Car bogged from 1st to 2nd
2) 15.62 at 92.79MPH- Removed air cleaner
3) 15.85 at 91.78MPH- Transmission failure, No 1st,drive or reverse after the run. So I had to drive home in 2nd gear.

My next issue will be with getting the transmission straightend out and to put an 8 3/4 with 3.91 or 4.30 gears. I think the Ol' girl might have some 13's in her!

Sounds like you broke the rear band in the transmission.
The gears should really help.
Good luck with the project.

Job well done. Stuff in a bigger cam and get that rear. You be a movin good.

From one 318'er to another.....

GOOD GOING!

More gear and you'll be pushing the 13 second mark hard.
Nice looking car!

Hey nice car, ill be running a similar set up only ill have a thermoquad carb, a bigger cam and from what everyones been telling me i should go for some 302 swirl port heads. I am surprised your rearend held up... Ive always thought 7 1/4s rearends were notoriously weak. Guess not. But anyways ill let you guys know what my shit runs once its all together in a few months.

[jkailholz@aol.com]

Yeah , the 7 1/4 rearends are pretty week. THey will hold up for a while as long as you don't get too much traction. I think I'm pushing mine to the limits. I figure if I break it, that is a good reason to put in the 8 3/4. I did break a rearend in a 77 chrysler Le Baron. Stripped all the spider gears right off. I think pulling out of school every day sideways didn't help it none, hahaha!

[71dart666]

Yeah thats what im planning on doing too, my 7 1/4 is a one legger and my tires are pretty small so it feels geared pretty low so I know I wont be able to hook up that well. But a 4.11 sure grip 8 3/4 would be nice.

How much for the car?
