I am looking at building a 408w. at first i thought about just buying a shortblock from a known vendor but i am the kind of person that likes to do things on their own. on my last short block i had help from my brother in law which made things a whole lot smoother. it was a 351w stroked to like 380 (old style stroker with off-set ground crank) but i think that it is time to upgrade.

i have my eye set on a 408. my brother in law says to just buy one. I was looking and pricing some parts and if i buy parts and do it myself then it will save me some cash and give me that experience of doing it. the questions i have are about "absolute must-do's" when building a 408w. most people i have talked to say that the most important thing is to notch the block to provide clearance for the rod caps/bolts.


the bore will be 4.03 with a 4 inch stroke 9.5 deck. it will have Victor jr Heads with a Victor jr intake


Is there anything else that must be done?
 
I'd buy one myself, I did it your way on my last motor, and I barely saved anything as I cannot do the machine work myself. Why not buy one from FordStrokers.com?

"machine work"--that is what i am trying to get at....

i already have a block that has the bore...but what else am i looking at?

Eagle Rotating assembly from summit 1,200 roughly...so does that mean just notch the block to clear the rod caps/bolts and put it together....??

i have priced some shortblocks...$3,xxx will get a "seasoned stock block"(what is that) with an eagle rotating assembly...

just thinking i could save some money to use elsewhere on the car.
 
I'm here:D

I had to clearance the bottom of the bores on my 408w... it was easy.
I'm not sure all rod setups require it though

Other than that, you just have to check all the 'usual' clearances before and after machining.
Basically build the motor to test fit everything before building it 'for reals'


Here is another good source for the rotating assy.

Jim can balance it for you as well, which Summit won't do.

or
Liberator 408w for $2500

just a couple other options,
