I'm putting together a 350 for the gasser. I was given a two bolt 1969 350 block, .030 over bore and ready to go. I have a good stock crank and am going to use flat top pistons with a compression height of 1.540" 5140 rods with cap screws, basically a stock bottom end. For the heads I'll reuse the Trick flow heads off of my 327, they flow mid 220 CFM on the intake and 184 on the exhaust. Speaking with a local cam grinder we decided on a cam with a ad. dur 282/282 224/[email protected] and 465/465 (1.5 ratio) lift and 110 LSA, ground 2*advanced. I know that these heads will take more lift and duration but I'm concerned with the two bolt bottom end do not want to grenade the bottom end, I know this engine is not going to be over 350 HP and 375Ftlbs, but this should make a fine street/strip motor right??? Any major changes???
