Thank Budnicks! I know I've picked your brain in the past on some of the engine details, when trying to put this beast together. I appreciate all the input you gave on it. Obviously turned out quite well.
GPuller...I'll take a look at the first couple pulls where they started at a lower PRM and see where that torque really hit the rafters. Down low she's still pretty nutz. No idea what to run for tires on the street. Any recommendations? Also..a torque converter hitting 3500-3800 sound about right for the torque curve? Gotta order that tomorrow along with the poly lock engine mounts and transmission mounts.
Your very welcome Prop, I'm glad to assist.... What type of tire when you go to the track or pick on the rice rockets in your area ??...LOL... What type of tire are you intending to on her, are you using a racing tire or street tire or a combo tire ??... IMHFO there's not really a good combo tire, you give something up, either handling or traction or wear..... But I found Comp T/A's do "pretty damn well" for handling, if you can find your sizes & some added traction once they're warm, but they are pretty expensive & don't last too long either thou.... But like anything with any soft rubber compound tires..... Drag radials are getting much better, for handling, but they aren't the best for street driving either, anything that has a soft traction compound or soft sidewall, will help to hook it up, but will also wear very fast, regularly street driven, especially at hwy speeds, if you drive around town mostly they don't heat up/wear anywhere near as bad... food for thought... I have a "reworked" 10" 3800rpm stall A-727 {
now, with the 479ci combo I currently have} originally it was a 175k Mopar Performance Converter #P4876879AB {
similar/like the old MP-J converter, behind Hemi's, but is actually a 10.5" performance converter}, I had an old tranny guy do for me years ago now, I'm going to use with 3.73:1 gears, I had very good luck with that combo, in my other old 68 RR's combo, never had too much issues with the trans getting too hot or slippen' the trans too much, something off the shelf probably wont do, talk to a converter expert, tell them honestly what your intentions are & how you honestly will be using the car, they will usually come up with a custom reworked converter for you... Use a B&M SFI rated neutral balance Round Dual Pattern Flex Plate too {
Like $83.95}, the stock flex plate is inferior with the engine torque you have now.... I would also highly suggest you get the book "Torqueflite A-727 Transmission Handbook" author Carl Monroe HPBooks-1399, a wealth of upgrades, tips & knowledge, also if you go with a manual valve body I would highly suggest to get a rear band apply style {
I use a Turbo-Action Cheetah w/rear band apply, Forward pattern $220 or so from Mancini Racing, had great luck using them on a couple street/strip High HP/TQ cars now} it will help to save the sprag/overrunning clutch from exploding, especially down shifting, street driving & doing burnouts, you have allot of torque now & needs to be addressed in the trans & drive line areas... Have fun driver her like you stole her.....
