Intake cam timing

Unfortunately, neither can Ford!

I agree with both of you.

Yes its in spec but that also doesn't make it right if the spec should be tighter. But we can kick this around until the cows come home.

I have had the opportunity to work on two of these engines for some upcoming stories we are working on for Muscle Mustangs Magazine. Both engines I degreed in the stock cams to see where they were before disassembly. Both engines the cams were off on the same intake cam several degrees. For sure no manufacturer will take the time to degree in cams exactly because it costs too much. I think that it is reasonable that they could do a better job than this however.

In addition, we ran one of the engines on the engine dyno for several days doing product evaluations on our products as well as the Whipple supercharger and the new Kenne Bell 2.8 supercharger. We also did a first version cam swap. All of the testing went well and we will be going back on to finish the testing again maybe later in the week.

I will do a follow up story when I am done with my testing. It is safe to say though that after several days and at least a hundred dyno pulls to 7500 rpms that the engine is very durable.

I think you are correct they could do a betetr job.

Varible valve timing, the "cat's ass"...

Varible valve timing would of been the "cat's ass", however with a supercharger, little is to be gained. The efficiency improvement would be nice though! Jay

If this is true would you be willing to have your motor pulled and have the top end disassembled for 25hp?

Not for 25 hp. If/when you pull the heads, seriously consider having custom cams done and installed properly. Additional head porting would be a secondary concern but worth research. Not to get into a head flow discussion, but I've heard about some very big flow numbers on GT heads from Al Pappito.

When I get my ducks in a row and purchase my GT, I'm pulling the heads and having them ported + custom comp grinds with SW headers/no cats. No other power mods needed; I can only imagine what it would sound like :thumbsup
