how fast are 289's

[Rev]

Tinner, the HP figures look kike this:

1.) 271 HP gross = (271*.80) = 216 net

2.) 216 net = (216*.83) = 180 RWHP for 4 speeds)

3.) 180 RWHP is actually more than some recent tests show for the 271 Hipo 4 speed early stangs.

4.) 15.6 is not unreasonanble for the magazine tests using bias ply Goodyears.
