Lt Cobra
my good friend Mike Lane build a FFR with mild 5.0 EFI. Drove it 12 to 15,000 miles and pulled the motor. He installed a 408 that was build by a local shop for $8 to $9,000. Put 20,000 miles on the FFR and sold it. Build a Hurricane and bought a KC 428 stroked to 461 with 601 fwhp & 619 fwtq for $12,000 +. He has about 4,000 plus miles on it now. He told me a couple of weeks ago that his next Cobra would have a 408W because it was more streetable, great power and the cost was reasonable. The 461 gets the ahhs and woos at the car show. It looks like the motor that was in the old Cobras. It's fast, very fast. Gets 14-15 miles to the gallon, if that matters. Every motor drives different. Take your time, do your research and any motor you pick will be a blast in a Cobra.
I like a small block in my Cobra. It's fuel injected, good mileage, all ways in tune and fast for a small block. I can hold my own at the red light.
But it does not impress the average guy at the gas station or car show. If you want a "real" Cobra then it needs a big block. And like several of the guys have said, a good FE can be build for $5000 to $8,000.
And thanks for the job your doing for us over there.
