So I'm planning on doing a stroker motor for my super bee over the winter.
Here are the for sure things: Stealth heads, 383 rpm intake and holley 750.
Should I go with the Muscle Motors or 440source kits? I have a line on a 1973 400 block (have to see if it's ever been bored out though).
My car has manual steering/brakes and a 4 speed with 3.55's in the rearend right now. 295/50-15's are the rear tire size. Down the line (next year) I will get an 18 spline hemi box and a dana(with probably the same gear ratio ~3.54).
I drive my car a lot and have only taken it to the strip a few times (best run of only a 14.5 w/ my low compression motor). Must have decent street manors and get at least 20 mpg (jk about the mpgs ) It has stock hp manifolds on it, but I will probably get rid of those in favor of some headers.

The prices on the two kits are comparable, obviously a lot of people talk down on the 440source stuff but it is what it is. I mounted my heads on right out of the box and had no problems with it. Muscle motors search on here shows mixed opinions.
This is my first performance engine build so any input is welcome!
thanks
