Build

t is no secret that if all other

things are equal, more displace-

ment will generate more torque

and power. As any Mountain Mo-

tor Pro Stock racer will tell you,

there’s no substitute for cubic inches.

That premise will be on display

as we set out to build a 347ci Wind-

sor engine from our stock 302ci Ford

platform. As came to light in a test we

did in Muscle Mustang & Fast Fords

some years ago when we compared a

306ci Ford to a 347ci, we know that

the additional cubic inches were highly

beneficial for power generation. In that

classic test the 347ci engine made 44

more horsepower and 39 more pound-

feet of torque with increased benefits

throughout the usable rpm range.

Our Engine Decision

Over the years, the Ford Windsor

engine has been cut up and modi-

fied in about as many ways as engine

builders can dream up. But with all the

testing, there are certain configura-

tions that seem to be the most popular

for this classic engine. The Ford 347ci

engine is extremely popular since

it is easy to find, and our 1987-

E7TE-code engine includes the very

cool and highly efficient hydraulic-

roller camshaft design. In this case,

we upped the 302’s game with added

stroke to generate more cubic inches

and that all-important, get-you-down-

the-track additional torque. For a small

additional cost, the 347ci engine does a

great job of delivering for both street-

and race-bound vehicles.

But there’s more than just addi-

tional cubic inches to making a better

engine. Take engine owner Saul Gutier-

Automotive owner Saul Gutierrez (shown here).
