This is my most popular Small Block Ford 347 Stroker Engine Combination

Discounted to $7000 Shipped


If you are trying to buy the most power with reliable parts for the least money, this is what I have come up with.
The cast steel/iron crank is strong enough for the street.
I'd recommend stepping up to forged steel if you plan to drag race on slicks or run a
lot of nitrous oxide.
It has forged pistons so you can run upto a 200Hp shot of N2O
The rods are Scat's 4340 steel with cap screw bolts. They can handle 7000rpm, cheaper 5140 rods can not.
To keep the cost down I use import aluminum heads, but if you have the money the AFRs will make a big difference.

How much power?
Torque is what is important and is easily calculated based on experience with particlar heads.
The import heads will deliver at best about 1.2lbs/ft per cubic inch, the AFRs about 1.3.
Therefore 347 X 1.2 = 416Tq 347 X 1.3 = 451Tq


Horsepower is a function of RPM. Have more camshaft duration means keeping the valves open longer.
This moves the efficency up the RPM scale causing the idle to become rougher loosing vacuum and low speed torque.
Have better heads allows you to use less duration to make the same horsepower as not so great heads, but keep more torque down low.


A 10:1 compression ratio 347 using 230/236 duration at @ .50" lift with Avenger 190cc heads will only make 325Hp 420Tq and the bigger 210cc version 370 and 430Tq
while the AFR 185 will deliver 450Hp with 460Tq.
The 210cc heads will make 450Hp, but need more duration to rev to 6000rpm and over.
