all the honduh kids give me such looks when i tell them im running an auto. Its unheard of in their little world. I simply reply with but I have torque and they get all and go back into their corner talking about iceman intakes and how i dont know anything about cars b/c im running an auto. LOL.

Look at just about all the bracket racers out there.. they all run autos. Granted theyre powerglides but thats still an auto.

 

for the most part youre right. Although the 413 isnt AS durable as the 727s and 904s.. it is pretty good. Turbo engines do give it a little trouble if you start upping the boost. THey especially hate high(er) boost at part throttle (if using a manual boost controller). But they can be blueprinted and beefed up using other stock parts from other ones and they become very nice!

 

blueprinting a trans engine carb whatever.. is basically tearing it apart and rebuilding it making sure everything is exactly in spec. No actual blueprints are involved i dont think.

Yes the front drum of the 413 is one of the big weak point (along with the valve body). The budget racers just stuff in an extra clutch pack into the drum. The better way to rebuild it is to either use a turbo mini trans or get the front drum out of a 3.0L 413 trans. Its bigger and holds more clutches yet fits (413 = 413... aint dodge smart!). People also tweak the VBs to make them shift better. Raise the line pressure. And put in heavier bearings.

 

tbi 413s are the weakest. Then turbo cars and tbi vans. Then Turbo vans. (I believe the spiders are stronger in the vans). Im not sure overall how the V6 ones rate... but v6s are junk anyway. I do know they have the good front drum.. which the Turbo Minis also will have.

 

but honda guys need the gears to get the revs high and keep them high so they can be in their sweet spot.
