Re: Starting 1966 Factory Short Bed Build, Bagged, 383 Stroker and Muncie M20 4-Speed
This is what I did:
Trapezoid inside dimensions
((a+b)/2)x(h)x(w)
((6.5 + 2.5)/2)x(14.5)x(48.5) /12/12/12
1.83 ft3
/2
0.9ft3
3x2.75x20 /12/12/12 (rough estimate of port area)
0.1ft3
sub: 0.05ft3 (typical)
0.9-0.1-0.05 = 0.75ft3 - but actually slightly smaller because I didn't take into account the separator board in the middle.
I ran both volumes through WinISD and there isn't a massive difference between the two. It will work. At .75 the box is tuned a few Hz higher.
