If you want to build it yourself them this is how I did it. Otherwise, consider buying a crate from Ford Racing or Southern Automotive.
Here are the specifications for my engine:
Parts:
1994 351W block from Ford Racing
Ford Racing 393 stroker crank
Eagle ESP H-beam rods
KB Hypereutectic pistins for a 302 w/ 22cc dish
Melling high volume pump
Edelbrock Performer RPM heads w/ 60cc chambers
Edelbrock Performer RPM cam and lifters
Edelbrock Performer RPM Air-Gap intake manifold
BG Speed Demon 750CFM mech sec carb
Comp Cams Pro Magnum 1.6 ratio rockers
Edelbrock timing chain
Edelbrock water pump
MSD Billet distributer w/ vaccuum advance
MSD wires
Blue Thunder main stud girdle
Blue Thunder timing chain cover
Canton Racing road race
oil pan and dipstick
Powermaster one wire alternater
March alternator bracket and pulleys
Ford Racing steel billet 157 tooth flywheel
Ford Racing crankshaft damper (needed $70 march spacer
)
ARP 12 point fasteners everywhere
Machine work done:
bored .030 over
block clearenced to fit stroker crank
crank fully balanced
pistons - valve clearance
pistons balanced
complete rotating assembly balanced with damper and flywheel
crank cross drilled for better
oil flow
heads had a full reworking even though they were new
All of this cost a total of about $9500. The machine work was outsourced. The assembly was done by me. It's designed to run on pump gas and produce about 430 HP. Compression ratio is 9.85:1.
Things I would change if I did it all over:
higher volume heads so that I could use a forged piston. The 60cc heads with the stroker crank required a large dish in the piston. KB was the only one I could find without going custom. I would use a roller cam. That's good for about 10-20 hp over what I have.
