Well i sold my cuda and iam in the process of buying and building another dart.I have a deposit on a 69 that has a smallblock,4 speed,dana60. Its a great deal and iam going to get it at the end of the month. Here is my delema. The car should go low 11s when its all said and done. I got a decent 440 built about 490hp. The car will probably be down the track about 20 times a season. It will be all steel so iam guessing 3500 lbs. The rear is built with good axles and should be able to handle it. My question is, will an 18 spline hemi box hold up behind it? If so for how long? Alot of my buddies said i will be repacing the trans twice a month! I really wanna run a 4 speed but i dont wanna constantly replace the trans. Any coments or suggestions? Thanks guys! Merry xmas!

Don't listen to those guys, 18 spline will have no trouble behind a lower HP 440 like yours.

Thats what i wanted to here! Also,will a b body 18 spline fit in an a body?

the trans will fit under the tunnel no problem, the issue would be where the shifter location is depending on what year b trans you have.

How about a 23 spline? There is one for sale for a good price out of an a body. I really dont know muck about 4 speeds so bare with me!

i have 18 splines in all my cars,with more weight and power.one is 870 hp and 3800 lbs.no problems yet...

I have seen an article on the web about putting a B/E trans in an A body. It's not that difficult, but you do have to rework the crossmember for shifter clearance.

Any chance you can get the A body trans and put the tailshaft and housing on the B body trans?

If it's not going to be an every weekend car I would think a stick would last a while.

Well, our team shirts say "Real Racecars have 3 Pedals" on the back so you know our vote.



18 spline is stronger than the 23 spline. Jamie Passon and Brewers Performance are both very knowledgeable about these transmissions.

So far, cross fingers, the 23 spline in our 70 RR is holding up. The 383 that was in it put out a little less than your 440 but definitely a heavier car. We have made plenty of trips to the track and run slicks when we are there. When I drained the tranny oil as part of pulling the 383 after dropping a valve in the engine the oil showed no signs of metal flakes or anything.

A body transmissions have a shorter tailshaft and housing than than B or E body transmissions. B and E body trannies have the same length, and any 70 and up 4 speed will fit either one as they are made with two shifter mount locations, forward for B body, aft for E body.

The car is already set up for the 4 speed, Run it with what it has, have fun with it, then drop in the 440 next winter if you still want to go that route.

You will definitely have more fun with the 4 speed, especially as it sounds like it will be more of a street car.

I think Lar 414 put a b/e trans in his 69 dart

If it's never gonna be a bracket car make it a 4 speed way more fun

Iam sold! 4 speed it is! Any clutch,presure plate recomondations?

did the car look anything like this

Manual is the right choice, at least for your family STW grocery getterhttp://www.youtube.com/watch?v=k7-Sf2yGRyk The nova in the other lane has been dynoed at 620 hp.

HaHaHa! thats it! Anyone know if proparts semi fenderwell headers work with stick cars?

1swingin,

Save yourself a lot of time and money and talk to Jammie Passon from Passon Performance and Brewers Performance.
They can answer all your questions pertaining to a mopar 4 speed transmission. Keep in mind those boxes have their limits and Jammie can fill you in on their limitations. He has done some really nice work with the stock cases and gears for them.

I have ran the "B" body in an "A" body 18 spline trans.

I still have the modified crossmember too.
