Kingman Posted April 18, 2011 Share Posted April 18, 2011 the downside is the ford engines would have less horsepower with the bigger cutaway it would drop the compression ratio but not by much lol The larger cutaways drop it .1-.2. And they put out the same power. Link to comment Share on other sites More sharing options...
Channel595 Posted April 25, 2011 Share Posted April 25, 2011 The valve dish in the pistons is for higher compression, not to make it a free spinning engine... as for snapping the timing belt, if you have an automatic and you snap the t belt while cruising you have a chance that there was no piston to valve contact but if you try and start the car after words your chance just got smaller. If you have a stick and snap the belt while cruising, the rear wheels are directly connected to the crank and you are still spinning the engine while bending valves, hope this helps Link to comment Share on other sites More sharing options...
Kingman Posted April 25, 2011 Share Posted April 25, 2011 Valve dish? Any time you take away material from the surface of the piston without changing anything else you gain cylinder volume, lowering the compression ratio - not raising it. Very good point about auto vs. manual. Link to comment Share on other sites More sharing options...
