These project do require some time, engineering, money and a lot of patience. Some of this has not been done before ina Cobra. Yes the SOHC engine has been put in a few but know we have all aluminum new SOHC engines that make 760 to 800HP on pump gas. It is all over kill and I would have not done the two Paxton package but our customer wants something over the top. He knows that nhe will not be able to use all the power but it is his car and we will build him what ever he wants. It will be an in line 2X4 set up since this is an eaqsy intake for us to get on the engine and one is made. If we did a cross ram style we would have had to done a sheet metal and that would have added even more money and time. The in line intake that we will us will make more power anyway. The trick will be to get the blowers mounted in the car on the front of the SOHC Cammer engine with that front cover that it has. There is going to be some engineering that will need to be done here and I know that Dave and Tom can handle it. Once it is done it can be repeated in the future.
The polished Cammer that was spoke of earlier is still in the early stages and hope that we get to start on it soon. It will require some extra work with the polishing and maybe a custom fab intake as well for the stack injection that is wanted on that engine. Maybe we can find an intake already done but not sure. I will have to get with the customer and Lance and go over the exact size we want to do and the power are looking for.
The 496C.I. SOHC we just sold had small camshafts in it and was dyno on pump gas and made 760HP by 7100 rpms and 630 ft/lbs odf torque at about 5000 rpms. It was a very smooth street engine that idled at 700 rpms and should drive great. It worked out very well. I can see with a little bigger camshaft along with a little tweeking on the heads and intake along with a little more compression or cubic inches that this would be a true 800HP pump gas engine that can be driven.
I am always a waite and see type of guy. When the parts became available we stepped up and did our own engine to see what could be done and how all of the stuff that was out there would work together. With the parts that we selected it all went pretty well. There will be a few things that we will tweak to make it a little better. We do not want to any engine that we think is going to be a problem down the road and this is why we waited a while till all of the parts were in place to do one right. So let the fun begin and we will try and take this stuff to the same level that we were told we could not do with a 427 SO FE engine just a few years ago by some of the FE know it alls. Like I have said many times before this is not your Daddy's FE engine any more.

Thanks and good luck, Keith Craft
