I personally think that those valves are WAY too big for a mild street motor with a cam that small. I think that a 1.94 is a more practical size.  Alex------------------

LOL Alex
I would agree though, 2.02 are good if you are planning on turning the motor some serious RPM's and especially once you have cleaned up the chambers some. The last couple sets of heads I saw with 2.02's had the valves massively shrouded...------------------

anything under .600 is still a good everyday driver if its set up correctly. Would probably be a 12 to 14 second 1/4 mile car. That's consider a mild street car. Anything that goes faster than that as a street car would start getting into wilder motor combos.Eric IP: 24.95.100.139 |

I guess that makes my 70 Boss with 2.19's a dog??? I don't think so. Anything that is properly thought out and executed will work. I have Twisted Wedge 202's on my 95 351W Lightning with the factory dished hypereuctic pistons. The valve size alone does not dictate the street manners of any given engine, rather the package taken as a whole including transmission type, final rear gearing and intended purpose. My Boss is set-up with 4:30 Drag Pack gears and a Clay Smith .615 gross lift solid cam with a whopping 258 degrees of duration at .050, yet I have NO problems leaving the stoplight - no bog, just smooth, kick in the ass acceleration.

66351stang,The pistons we went with "trw light weight race pistons" I'll get their part number if you want, have only 2 valve reliefs and cleared the 2.02 valves with .120 clearance with the 282S Compcam. I'm not disagreeing with Alex's advice, but you can run 2.02 valves if you want with the lift you're considering as long as you go with the right pistons. Whether or not the increased Intake vale size is worth it is another matter, as the Fords need help on the exhaust side more than the intake.  SteveW IP: 205.188.195.181 |

Steve just made my point. The larger valves won't hurt anythng, but they won't make anymore power. As a matter of fact, they will make less power under 7000 RPM with a small camshaft. In MM I use a camshaft that has close to .800 gross valve lift and I only can use a 1.78 OD valve. I have many street and strip engines floating around with .600 + lift cams. All solid or roller of course. Alex------------------
