In 24hrs I will put up the numbers and we'll see who wins an all expenses paid trip to Nowheresville! Heres a list of all the motor details, as I can remember them, built it last June. I put it in the car and drove about 30miles in August. Had an oil leak to fix and figured I might as well dyno while its out.
- Block is a '73 340 that is .030" over (oiling mods and lifter bores bushed)
- Eagle crank and H-Beam rods, 4" Stroke 416 cubes total
- Melling Hi-Volume pump
- Mahle -5cc pistons Calculated static compression is 11.7:1
- MRL Performace Billet Main Caps and Hughes stud girdle
- Heads are Indy 360-2 w/ 2.10" Intake and 1.65" Exhaust
Ported and polished, no idea on flow #s. Rockers are T&D 1.6 ratio
- Indy intake, port matched to heads by moi, only polished up each runner, none of the plenum area under the carb is polished (still rough cast)
- Cam is a Lunati #60434. Duration at .050" intake is 255, exhaust is 263
lift is .643 with 1.6 rockers.
- Running a Demon 850 with 86/91 Jets (for best pull)
- timing at 34deg (for best pull)
- Fuel is 50:50 mix of C12 and 94Octane
Elevation at test was 2500'
Temp was 68deg
Barometer 27.4
Humidity 24
Lets see your best guess
