Big cam, low compression lends itself to a spread bore, because airspeed will be your saving grace down low. If you go with a TQ a later one would be best. They have bypass air in the idle circuit, something that cams with more overlap need because the spread bores primary boosters are so sensitive, too much throttle angle at idle will start up the primaries too soon. Same with the QJ. Bypass air will be your friend.
