Yes it could. I mean, you're not asking much out of a 340. 1.07 hp/ci? The last 340 +.030 we did was 9.37:1 compression with J heads that flowed 256 cfm @ .550". 6-bbl intake and a solid flat tappet cam 234/238, .523/.538, 106 LSA in at 104 ICL. It peaked at 1.174 lb-ft/ci, 1.226 hp/ci and was making 404 HP @ 5,700 rpm. It went into a 1970 T/A Challenger and has maybe 10 miles on the engine. Been locked in a metal shed for a year(?) now. Will be a heck of a barn find some day.
