rev, the cam is a summit with .471 lift int./ext with 218 intake duration and 228 exaust duration at .050 lift. the lobe separation is 114 for sounds good for a street cam. i definetly agree with you on the headers, he shouldnt have listened to the summit salesman, but he's new at this game. my mistake was not telling him to get the 351 cam....for some reason it works better in a 302 because of the firing order. the heads are shaved, not sure how much the machinist took off, but they have extremely small chambers to begin with. now i know a stock 5.0 has the same valve size as a 351w with larger chamber heads (61-64cc) so it seems the valve would be so close to the top of the bore that valve shrouding wouldnt be a problem. i know also that the runners on all stock small block fords(windsors) as well as the ports are the same size. there are flow variations between early model/smog heads but look at the ports on a 289 head and a 351w head....exactly the same size. the hi-po heads also have same ports. sorry about this being so wordy, i just think this car should have a lot more power than this, 9.6 in 1/8 for this car is sad.....a bone stock 5.0 is quicker with 2.73 gears/444 lift cam/and weighing 3200lbs. thanks for your replies.
