Building the perfect 351W

here's my "recipe"

Early 70's 351W from a ranchero, why? I got the whole thing for $300.00.
The engine was already bored .30 over, so after sonic testing the block we bored it .60 over. Next came the scat crank to make it a 393 + with the bore. The rods were reused after reconditioning (shot peened, magnaflux) The pistons are badger hyperutectic with hasting rings and recessed with a cup to give about 9.7 compression ratio. The cam is a xtreme energy xe262h with roller rockers. I used magnum push rods and edelbrock rpm aluminum heads #60229.
The timing set is a roller also. The intake is an edelbrock rpm with an edelbrock 600cfm carb. Fuel pump and water pump are also edelbrock with a different base on the fuel pump to have the lines clear the block. It has a ford electronic ignition with mallory box. I have about $3000.00 in the engine. I didn't get it dynoed but figure it should put out around 400 hp and torque. I bought most of the parts from Lesco Automotive Industries and had the machine work done locally. I'll let everyone know how it runs next summer when I get it installed in my 68 bronco.

Sounds pretty cool... I wonder for all of you out there who have stroked their 351W, if they've had any problems passing emission tests. I ask, because here we have to have our vehicles tested anually and I would hate to spend all that money to find I couldn't pass testing.

It all comes down to your camshaft, intake and head combination. There are plenty of stroker motors that will pass with flying colors. It really depends on the top of the motor, the bottom end has little bearing on its emissions.

Since you guys are talking about the roller cam engines, I thought I'd throw this question out. I have a 94 roller 5.8, and I plan on doing a 408 stoker in the next couple years. What I've had a hard time determining is if I want to keep as much torque down low as possible, but still develop as much power as I can, whats the best roller cam to get? I ask, cause I'm not real good with cam specs yet. Are any of the FRPP roller cams good for a low end torque monster (B303? E303?)? Should I build the stroker and keep the stock 94 roller cam? Any ideas appreciated!

I think the stock will make that thing fall on its face at 3000 RPM. The thing about a stroker motor is you can put a big cam in them and the long stroke makes up for it. I would use something in the E-303 or the F303 range on a 408 inch motor. You will still have awesome low end torque and lots of midrange horsepower.

Thanks, I kinda suspected that the stock cam would limit my top end, but I wanted to confirm that. I'm glad to hear that the E or F bumpsticks would be good choices. I don't mind having to go non-OEM for a the right cam, but those Ford cams are really affordable compared to the aftermarket vendors. Like I said, my main focus is maximizing low rpm torque, but at the same time I'd still like some mid-range fun power ;D
