OK. I said I'd print the results of my research with the Windsor engine on the Dyno 2000 software so here it is. Basically I was looking for something in the 450 to 500 hp area with about the same or slightly less torque. It's going to be hard keeping this much hp anchored without going to a pro-street setup so I saw no need to go bigger. I did find a significant difference in the amount of hp and torque with the stroker kit as well as how long it was maintained, so I believe the stroker kit is well worth the extra bucks. The decision I haven't made yet is whether or not the roller cam valve train is worth the extra bucks ($700 for cam and rollers). I've heard a lot of stories about lifters turning sideways and screwing up some good engines. Any opinions?
This is what I used for my baseline engine: 351 Windsor block bored .030, stroked to 3.85 in., Ford N351 sportsman heads, 9.50 compression ratio, 750 cfm carb., large tube headers with mufflers.
The first setup is using a Crane 443941 hydraulic cam and lifters. Intake dur. 272, lift .484, exhaust dur. 284, lift .512.
2000 rpm 157hp 411lb/ft
2500 199 418
3000 243 426
3500 295 442
4000 347 455
4500 396 462
5000 436 457
5500 465 443
6000 482 422
6500 486 393
7000 476 357
The second setup is using the Crane 449541 roller cam and lifters. Intake dur. 278, lift .520, Exhaust dur. 286 lift .542.
2000 rpm 167hp 437 lb/ft
2500 208 438
3000 252 440

6000 532 465
6500 539 435
7000 539 405
The horsepower and torque curves are pretty flat on top using the roller cam, but what about reliability?
Plenty of good ol' horsepower though!
