408" with 6-8 lbs boost

Built many engine's,probally 40 gas burners and 75 or so Detroit and cummins and 3 cat diesels..only turbos and superchargers though were on diesels.My second car in 75 was a 70 Dodge Challenger, been Mopar or no car ever since.This is to give me something to play with while I build my 73 duster if my pain will cut me some slack. I'm just thinking that the extra load on the longer stroke with boost might not hold up well,but I could very well be wrong. I like the idea of boost because I can keep the 3.54 gear and pathetic gas mileage or go n/a strokers and 4.10 have horrible gas mileage.
