Nissan 240Sx(SR20DET)S-13 Style VS 89 Mustang 5.0

[duplox]

9500rpm is a bit more than half the redline of an indy car.. I've seen late models run low-mid 8s on a stock cobra bottom end. you can buy a '96 cobra with the aluminum 4.6 short block that'll handle 800-1000hp for around $8000. Thats car and all - throw another 5 grand into it for new injectors, a turbo, a new EFI computer, suspension upgrades, subframe bracing and you have a 700+hp machine. Now if you want to talk old cars, back in the day you could buy a 658hp 427 SOHC cammer for a little over 3 grand, over the counter, at your local ford dealership. My uncle did it, put it in a '67 fastback. Too bad the car is gone now.. that motor and car would most likely be worth $60-100k today. Of course in those days, the motor cost as much as the car!
By the way, in my cleveland, I'm running a stock block, stock crank, and stock rods... pistons are aftermarket. I've done a little modification to all of them(1/2 filled block, polished/shotpeened rods, ARP wave-loc rod bolts, deburred block, micropolished/deburred crank, main studs w/ girdle...) but considering its all nearly 40 years old, I think its pretty damn good. Sure if it had overhead cams and modern block casting techniques and other new tech, it'd be a lot stronger and make more power... but thats what we got the 4.6 for, dont we?

Oh, and its not a 5.0.. its a 5.7. And not a windsor.. cleveland baby! the winningest ford engine of all time.
