Hi all,
In another post I asked a dumb question. My real question is can a 2 valve 289 C code be made into a 4 valve motor? Also is the 4 valve 289 the A code or K code? What is the difference other than more horse power?
Thanks, Walt

 

Walt, I think you mean is can a 2 venturi carburated C code engine be made into a 4 venturi carbureted engine. The answer is yes. You have to change the 2 venturi intake manifold to a 4 venturi manifold and add a 4 venturi (barrel) carburetor. The biggest difference between the C code engine and the A code is primarily the 4 barrel carburetor with a 4 barrel intake. The K code gets into the internal parts of the engine with several upgrades.

 

V=venturi now I get it. I thought that 4V was 4 valve. [sm=lol.gif] Now I'm not so confused as to make my 289 a A code. What did they do on the Ks to get more HP? Higher compression pistons and cam?
Thanks, Walt

 

K code = solid lifters, cam, intake?, head work to support the solid lifter cam., hipo manifolds

 

4 valves per cylinder is a relatively recent development for production cars...beginning in the 90s IIRC.

 

a code also upped compression i believe

 

You`re right. This is copy/pasted from "FordClassics.com":

1964 1/2 Mustang
A choice of four different engines.

170 c.i. @ 105 h.p. w/9.1:1 compression and a one barrel carburator.

260 c.i. @ 164 h.p. w/8.8:1 compression and a two barrel carburator.

289 c.i. @ 210 h.p. w/9.0:1 compression and a four barrel carburator.

289 c.i. @ 271 h.p. w/10.5:1 compression and a four barrel carburator.


1965 Mustang
A choice of four different engines.

200 c.i. @ 120 h.p. w/9.2:1 compression and a one barrel carburator.

289 c.i. @ 200 h.p. w/9.3:1 compression and two barrel carburator.

289 c.i. @ 225 h.p. w/10.0:1 compression and a four barrel carburator.

289 c.i. @ 271 h.p. w/10.5:1 compression and a four barrel carburator.


1966 Mustang
A choice of four different engines.

200 c.i. @ 120 h.p. w/9.2:1 compression and a one barrel carburator.

289 c.i. @ 200 h.p. w/9.3:1 compression and two barrel carburator.

289 c.i. @ 225 h.p. w/10.0:1 compression and a four barrel carburator.

289 c.i. @ 271 h.p. w/10.5:1 compression and a four barrel carburator.


1967 Mustang
A choice of five different engines.

200 c.i. @ 120 h.p. w/9.2:1 compression and a one barrel carburator.

289 c.i. @ 200 h.p. w/9.3:1 compression and two barrel carburator.

289 c.i. @ 225 h.p. w/9.8:1 compression and a four barrel carburator.

289 c.i. @ 271 h.p. w/10.5:1 compression and a four barrel carburator.

390 c.i. @ 320 h.p. w/10.5:1 compression and a four barrel carburator.

 

Howdy,
I thought the C code was 210 hp?
