My 68 Fury H/T lists at 3680 lbs with a 383 - 160 more than a 68 GTX with a 440, so one of the "least bulky" C's, BUT it has A/C and a 9 on the build sheet for underbody protection, its pretty thick down there - saw someone say they got 90 lbs off their challenger by removing the all the goop from underneath, scary.
My aim is for 12's (high 11's?) and still be able to drive the 125 miles to my nearest drag strip with a 383 stroked to 450 @500hp comfortably
Have ally intake, radiator, water pump n housing, ally heads are my next purchase.
Ideas swimming in my head:
Loose as much of the front as possible and leave the back end alone until scaled, the ass-end is easy to lose weight from
Split bench in currently, will pull and weigh and evaluate, most likely to be replaced with some Japanese oem seats of some description (safer than cheap sports seats)
LiPo battery in the pass side of firewall, shorter runs for heavy cables
Re-wire with decent new txl wire and get the voltages required down everywhere I can
Replacing all the A/C with lighter options - sanden compressor mounted below alt on pass side and more ally pipe vs rubber hose, same with the heater hoses. Its a huge temp variance where I live, 37 to 115f, need a heater for local regs and A/C cause it gets bloody hot
Replacing as many engine bay brackets with ally as possible
Drilling Vee pulleys in the space at the the bottom of the V and lots of holes wherever I can (evenly for balance)
Cutting the exhaust crossover and coil mounts out of the performer intake and a few strategic holes elsewhere
Steering Rack from one of our local fords, havent done proper measurements but its not too different in width to a mustang rack, which isnt too far off whats needed for a C and way lighter than the box/drag link set up
Front Brakes, have the 2 1/2x11 drums, have the 69-71 11.75x1.25 disk brake set up, its heavier than the drum set up.... will be adapting to 11.75x1.1 disks from the same local ford above initially (cant get the original rotors here) and lighter calipers later
Wheels, tricky here, there are not alot of actual lightweight rims floating around in correct pcd and offset used here, holding out for something that looks good but isnt heavy, 15's or 17's x 8-10, whatever comes up for good value, currently only have 14's so need to go up for the disk setup
Radiator support, bumper brackets & headlight buckets re-done in ally
The inner fenders bolt off, but are structural until some frame connectors get added, then I will look at ally or fiberglass or carbon fiber, steel are 12 lbs ea
Here we are not allowed to use external fiberglass front panels on the street unless its certified by a manufacturer/certified specialist - completely custom and going to be out of my budget for some time, pretty sure my sheetmetal skills arnt as good as FMJ's and I doubt I would be happy with any ally hood, guard or bumper I could produce
If the Windscreen (windshield for you guys) ever breaks, the dash will come out and be done with F/G or C/F , before that will crawl under and have a look at what steel can be replaced with ally, prob at same time as AC
The door vent glass has a winder mechanism, that can become fixed and lexan, small cranks moved to the regular window winders
I can live with the back widows becoming fixed and possibly lexan, I have AC and rear passengers be dammed
Plus lots of the little things mentioned on this thread, drilled bolts and suchlike
