BowTie Posted July 14, 2004 Report Share Posted July 14, 2004 Here is the deal 350 chevy .40 overbore 9.5-1 flat top 4 valve relief pistons stock crank plain ole basic. Crane cam .333 at the lobe, 500 at the valve with 1.5 rocker 373454 casting heads (stock chevy p/u) 76cc chamber. Nothing done to them halfway down the straight, at about 5000rpm the engine has missing/loss of power stock valve springs with spacers. Question. If you have limited time and very limited money to spend, do you put on stronger springs? Mill .30 off the heads first? What about coil bind? Stock rocker arms also. I have no access to other heads that would be legal. Any input on improvement would help me. Thanks Link to comment Share on other sites More sharing options...
