Got to thinking about my old K code and found this. http://www.midcomustang.com/mustanghipo.shtml

"The K-code cars are an absolute blast to drive. With a 6,500 rpm redline (7,000 if you’re feeling lucky), a close ratio 4 speed, and a 3:89 rear axle, high 14 second 1/4 mile times were possible. The car just explodes from about 3,500 rpms (when the vacuum secondaries open) to the redline and the engine/exhaust sounds incredible."

So, I am surprised that a V6 with a tune, exhaust and intake and maybe gears is very close to the K Code. The K code certainly sounded and felt much faster than the V6.

I think I may have to disagree on a couple of these comparisons . THe 327/350 that was mentioned was in a 66 chevy II and ran 0-60 in 7.2 and 15.1 1/4 mile stock. The 289 /271 hp in the mustang ran 0-60 in the low 7s and low to mid 15 s 1/4 mile stock. These cars were actually not faster than the 4.0 v6 especially the manual . The 4.0 v6 would also easily beat the 289/225 hp. Those old hp numbers are also rated in gross hp. Comparing gross hp to net hp for instance that old 289/271 hp if converted to net hp would actually be around 210 hp and the fact that the 4.0 has better gearing , 5 speed vs older 4 speed

Davesyo, you da man!

Exactly whatI was thinking. Our V6 Ponies are right where I would have wanted the power band to be to emulate Pony, not Muscle car performance of the 60's.

Hey, I know all about these things . You know, those older 0-60 and 1/4 mile times . Oh, and that 66 chevy II, that car could scream . With only a little tweaking 1/4 miles in the 13s were yours . But anyway just for comparison a stock big block 389 66 gto did 0-60 in 6.6 and right around 14.9 1/4 mile. Pretty close to what the 4.0 does .I guess we can't complain.

You other old guys know it depended a lot on the driver too. We had crapy bias ply tires, crapy gearing from the factory (2:73's) that's why I mentioned Pure Stock. I was running 14.40's with my 65 GTO and had a 70/400 in it. !3's with 4:10's andwhen I had a Ram Air 4/400 I ran 12.40's. But we're all right. A lot of the old 60's cars weren't all that fast by todays standards but it didn't take much tweaking to drop off a second, sometimes just dialing in the distributor and jetting could give serious gains. I do like the power my 4.0/V6 has.
