Sean, all....
I have been kicking around this very thought. Here is what I came up with
1. Heads would have 63 cc chambers with 1.9 inch diameter intake, 1.6 inch
diameter exhaust.
2. Valves woul dbe stainless steel, behive springs and titanium retainers
and keepers
3. Compression ratio would be 9.5:1
4. Dual Plane high flow intake manifold (extrude honed and port matched)
5. 700 cfm vacuum secondary carb
8. Small tube headers
9. Cam:
a. seat to seat specs- intake 252 degrees, exhaust 261 degrees
b. intake centerline 106 degrees, exhaust center line 112.5 degrees
c. intake lift 0.510 inches, exhaust lift 0.510 inches
d. cam lobe center 109.3 degrees, overlap 38 degrees
e. hydraulic roller cam conversion
10. Pro MAgnum roller rockers
11. Heads modified for screw in rocker studs (or if AFR, not required, part
of deal)
12. Electric water pump
13. Ford Electronic distributor (kind available around 1978 or so) with
electronics box
14. MDS 6AL ignition system
15. Electric fuel pump with regulator and return to tank line
16. Alternator
Alternate:
1. Use EFI system from 1989 - 1993 Mustang modified to fit the car (carb
manifold modified with bungs) and Tweecer
This option is more costly but might yeild more driveability if going up and
down in altitude.
Dyno Curve
rpm Fly Hp Fly Torq
1000 41 213
1500 71 249
2000 110 288
2500 150 316
3000 186 326
3500 226 339
4000 265 346
4500 297 341
5000 324 331
5500 346 331
6000 357 313
6500 359 290
7000 352 264
Then I might do this to my 289 5 bolt block....
