HELP w/ Cuda converter selection..
« on: February 23, 2004 - 04:46:50 PM »
Well I'm finally ready to install the freshened 340 / 727 into my 71 shaker cuda.   ;D I'm wainting for my headers to come back.. sent them out to be Alum coated. Found this place Airborn coatings in CT.. inside & out for $205.00).  :-*

Anyway, I'm not sure on what stall I should be buying. Pls help... This will mostly be a SAT night special, with some runs at the local track. II'd like drivability and high 12's track runs.. Is this even possible w/ my internals?  ???The basics of the 340 are as follows..

72 340 block, std bore, forged pistons / crank. T/A heads (offset rockers) w/ mopar roller rockers.  The T/A heads have been "opened" up very nicely.. awesome flow rates, offy duel plane, topped off with a Demon 750.
Lunnati cam is mechanical 235 duration and 528 lift. HP = between 450+. Rear is a 3:91 sure grip.

I really can't afford to chirp the tires every time I put the car in drive, but I don't want the car to fall on its face when I race either. I'm thinking that 2600 stall get's me into the high 12's and drivability.. or am I way off base.

Also, anyone know what the stock stall was on the 1971 340 converters??

Thanks as always to you gurus out there. My machine guy said the ported & polished T/A heads will really make this 340 jump.. he said I should have no problem running 12's.. i dunno. Thanks! I appreciate everyone's feedback.. luv this site!  8)

IMO i think the 2600 up to a 3000 stall would suit you nicely  ;D

Always best to let the pros decide, it's there living.
Decide which brand you want and give them a call. Explain your set-up and decide together.
Tell them what you want the car to do. They'll be more than happy to help, FREE  ;)

REV did the same thing and found what she needed, she got her new vert in about a week after calling.  :)

NZ's right.  The folks working at the converter shops seemed to all be very helpful and willing to spend time figuring out the best converter for how you will be driving your car.  

However, CP could probably tell you just what you need without ever having to pick up the phone.  ;D

ps...get the correct flex plate before you get ready to install... :P

you want to be approx 2600 rpm or more with that duration , make sure you are approx 200 rpm above the minimum rpm on the rating for cam
