I can't stand it it's driving me nuts!!!

I went from literally 24 mpg to 18 mpg when I sold my heads and cam. The power loss is more then I can bare.......

I ordered a reground cam and will be doing this shortly! LOL

Now I know why all the still stock engine guys complain about MPG'SSSSSSSS

Uncle Uncle. I give......LOL

So looks like I will just throw a 6.1 cam in her advanced 4 deg. Should be good for some 13 sec passes.....

I am not in the mood to pull the heads to put spring on..... So a 6.1 cam it is.

You know the 260 cam has les lift then the stock 6.1 cam and a little more duration on the exhaust side..... Along with the 260's 113 ICL instead of a 119.5 ICL of the 6.1 cam. So advancing the 6.1 4 deg will be 8 deg at the crank. That should put me at 111.5 ICL this should build some cyl pressure ehh......

Will the PCM be able to handle the cam being advanced that much being the cam position sensor will be out of phase with the crank position sensor from the factory setting?
