Or you could do something in the middle of the road cost-wise, and go 351W stroker...393/408/418/427/429/460/etc. The 408 is a a super popular option and would probably be the route I'd go since you can do a somewhat budget-minded 408 stroker build without breaking the bank. Good power, torque, reliability and as close to bolt-in as you're going to get for a non-stock option engine.
