After working with current Mustangs, I dont want a Camaro to get a OHC/DOHC. Ive had enough of it. Its more expensive and time consuming to do mods. Not to mention aftermarket is slower. Thats the main attraction I have with LS engines, besides the superior power numbers.
Most old school wrench jockeys can do a cam swap on a LS anywhere, but with SOHC or DOHC most of them guys dont even want to help even with a case of beer. With Mustangs the only option you have is third party port work or hope Ford comes out with a better design soon. With LS engines or most OHV engines; you have a hand full of aftermarket companies producing head.
OHC is great if the car is going to stay stock or get nothing more than bolt-ons and supercharger. But I miss having a car that can be brand new and still be tinkered on and even your friend have fun helping. Maybe I am biased and have been scarred by Mustangs.
