I wouldn't hesitate to use a cam like your thinking with 106 to 108 LSA and install it at 102 to 105 intake lobe center One of the best HP and torque producing 906 iron headed pump gas stock stroke 440 motors I built had a Reed cam with 101 LSA(installed at 99 ILC) similar duration like your thinking and .560 lift with 1.5 ratio rockers That racal had a bunch of tire spinning bottom end and it would not quit pulling hard up to 7000 RPM according to the customer
Back when I first started learning about camshafts we would use a close (104 to 108 )LSA on the automatic cars and a wider(110+) LSA on the stick shift cars, the thinking was and is the closer LSA help the bottom end, below 5000 RPM, and the wider LSA move the peak power up above 5000 RPM That still applys for me BTW, my bracket motor(505 C.I., 14.3 to 1 comp. ratio) runs on pump E85 with a 108 LSA solid roller cam installed at 106 ILC, runs good, last a long time after I got the rocker arm situation worked out on the Eddy M.

Make sure your fuel system will provide enough volume(30% more needed at least than for gasoline) for running on E85
