Need help keeping up with C6 Z06 & Porsche GT3 on Road Course
Copy Tim Werner's 68 Valiant.
Mitch's 70 Challenger is purpose built for SCCA Autocross E-Street Prepared class. That is class racing in true competition; ie rules. Mitch's setup will hold you back for what you want; road course.
Tim Werner's 68 Valiant going off my memory. Hopefully AndyF will chime in with more details.

Tires/Rims
Chassis
Notes: You need to baffle the center section to axle tube connection with Seals-It axle tube baffles. AND weld gate plates with holes in bottle to baffle the side ramps inside the round center section housing. You need to run a remote axle vent tube. Up at the top of the floor board or into the trunk compartment.
If you go 5.7 Hemi can you get the motor with same ground clearance as a stock motor? Meaning level with the bottom of the K-member. Will the header for the 5.7 Hemi (TTI's) has the same or less ground clearance as thier LA small block headers.
If you go 5.7 hemi does the oil pan have equal road race baffling as the Sm block and Big Block Milodon pans? Remember when Tim Werner tested his car with the new motor he could run easy with C5 Z06's, but the Charlie's oil pan couldn't keep up oil pressure and he had to put it back on the trailer. Now he has a Milodon SB road race pan.

Motor
- 500 hp/500tq 427 cid stroker aluminum head
- see Mopar Muscle article for build details: http://www.moparmusclemagazine.com/...8_plymouth_valiant_427_engine_swap/index.html
- see Moparts build for details: http://board.moparts.org/ubbthreads/showflat.php?Cat=0&Board=Racer&Number=5406049&fpart=&PHPSESSID=
- if you choose some other motor you need an oil pan equivalent to the Milodon Road Race Pro touring pan
- Dougs header for slightly more ground clearance than TTI's
Suspension
- 1.24" Torsion bar
- bilstein shocks
- Firm Feel tubular upper control arms
- Firm Feel strut rods (but I think poly bushings. This was before people came out with spherical end strut rods)
- road race leaf springs (I believe from Firm Feel. IMHO Hotchkis will be equivalent
- AREngineering Brembo or Baer 6 piston conversion with 13" rotors and aluminum hubs. He currently runs the Baer caliper.
- I think he just runs rear drum brakes
Tires/Rims
- 275/40/17
- 17x9 mustang rims
Chassis
- 3130 lbs with a 55/45 split
- full cage
- front down bars tied to shock tower/inner fender
- subframe connectors
- 8 3/4 rear 2.94:1 ratio rear gear (I think clutch sure grip)
