WEBMASTER'S NOTE: The following is an ongoing project
by Wes Adams to build a "Poor Man's 427", using a Ford FT 330 block
and other 'cast-off' parts. The posts were saved from the FordFE.com forums
and reposted here with Wes' permission.
As you can see we have some seats
sitting here for the heads. The outer diameter of the intake
seat is 2.253" & the exhaust seat is 1.753".
Here we're cutting out the seats on the intake side of the
head.
This is what it looks like without the seats in the head.
Here is Bill installing the intake seats in the head
WOW! Those seats look like they are made for those
heads! That
is way cool if you ask me.
After we installed the intake seats, we had to true up the
head
in the machine so the exhaust would be the same as the intakes.
In this picture we are doing the same thing to the exhaust side
of the house.
This is what it looks like with it cut out.
As you can see in this picture that we have a little ledge left.
We need that little ledge there or the exhaust seat will come
back out after we put a few hours on the engine. Remember that
we have a good size roller cam going into this engine, so we're not going to take a chance like that.
Here is Bill installing the exhaust seats.
Here are the exhaust seats in the head.
Here we're cutting out the inside of the
exhaust seat, to get as much flow as we can out
of the head! Scott is going to have a lot of bowl work to do. We're hoping to get some killer flow
numbers out of the heads but you
never know until you give it a shot!!!
Here we see the inside seat cut out. Wow, what a thin darn seat
that we have here!
Here we have the killer valves for the heads. We had the
exhaust
cut down from 1.75" down to 1.72". We wanted to make sure
we have some clearance between the intake & the exhaust valves.
Now the exhaust valves have all
been cut down to 1.72". The one on the left hasn't had a seat
put on the valve unlike the right side. Our seat angle is 45
degrees. Then we put a 30-degree backcut, then another 20-degree
backcut above that. That was some work but I think it will pay
off in the long run. Then we did some polishing of the valve.
MAN, I call that "backyard mechanics". Doesn't get any better
then this right here!!!!
Here we did a real rough cut on the
exhaust seat to see how the
valve sat. We took some valve compound and spun the valve in the
seat to see where it was hitting on the valve. We wanted to
leave Scott some room to do his work. We do plan on
moving out toward the outer part of the valve
once we get the heads back.
Once we get the intake valves back (cut down to 2.15") we will
do the same thing on them as well (just like the exhaust). I
hope you enjoyed this long issue of "The Poor Man's 427".
