Last engine made 565rwhp, 306, TW 170 heads, t-trim 16lbs boost, AFM B-451 cam.
I really liked that AFM B451 and would be my cam choice for boosted applications. You do need to get their valve springs as well for the b451 however. Made 515rwhp with a F303 prior to cam and spring change.
Stock block 306, V1 T-trim, AFM B-451 cam, TFS Twisted Wedge, Holley Systemax, A1000, Snow Meth, TKO 600, Team Z, Strange, MM, Lakewood and Moser helps me go forward fast.
