As far as actually installing them, it's not that hard. Nowhere as easy as a pushrod cam. The 4v specific cam tool seems like it would be a nice help.
So are the following specs incorrect??if you want cheap gains for a N/A 4v put some 03/04 mach 1 cams in it. A hell of alot cheaper than a set of aftermarkets and it will get you around 18-20 rwhp gain. A set of used aftermarket one will compliment your other mods decently with a good tune.
I don't remember where I ran across these, but if you have different numbers let me know.96-98 Cobra Cam Specs:
Intake: Primary Lobe 196 duration (at .050)/ 390 lift
Secondary Lobe 206 duration (at .050)/ 390 lift
Exhaust: 196 duration / 390 lift (at .050)
Mach 1, 03/04 Cobra, Aviator, Marauder, 93-98 Mark VIII, Navigator.
Intake: 184 deg @ .050"/0.394" lift
Exhaust: 196 deg @ .050 / .394" lift
Which specs are you talking about? You mean putting the smaller duration intake cams in? Nope, its not wrong. That car has the B heads on it and could benefit from less intake duration due to the 2 seperate ports that have a total of 222 cc's of runner volume. Thats alot of volume for only 281 ci especially if the IMRC plates have been deleted.Thats more intake runner than most people put on their stroked 302's! Granted you will loose a little top end power but gain low and midrange which will make it a better street car, if he likes more top end then retard the cam timing a couple degrees. Now if he would like to keep his stock cams and get more power out of them, then his stock cams will make more power out of a tumble port or a C series head due to the single intake runner and only 177 cc intake runner volume. Another interesting thing between those 3 heads is that the 99-up heads flow a little more than the 96-98 heads with a smaller runner, which means alot more velocity and could play a role in why those heads respond to the early cobra intake cams better than the B heads do and vice versa. Or maybe even advance his stock cams some.So are the following specs incorrect??
