I have a 1951 Ford F3. The engine was rebuilt within 5000 miles ago. I think the bore is 3.268. I want to build either a 4.125 or 4.250 stroker. I really do not want to machine the block and prefer just to install a stroker piston with a 3.268 bore.

I will source the Eagle crank and H beam rods from CNC machine. My next order of business would be to source a 3.268 piston or have the block machined again for 3.312 pistons.

Lastly, do the eagle rods require a bore notching to fit?

Oh an could I get away with just using the 3.75 stroke crank, adding a cam, 2 carbs, and machining the heads for a good driver? I know when I build drag bugs that the stroke makes all the difference.

As it is now, I may source the stroker crank and rods from CNC motorsports for a little over $1100 with 3/8ths rod bolts on a chevy journal

What say yee for a nice running 1951 Ford F3 with Borg and Warner 5 speeds , dual Strombergs, 236 effective at 050 .355 lift, 3.73 posi.
