Black2003SS Posted October 18, 2007 Report Share Posted October 18, 2007 My first piece of advice would be to ditch the granetelli MAF and go back to a stocker. Obviously, bigger injectors for under a 3.0" pulley. As far as cams go, there are alot of choices, but two come to mind right away. The lingenfelter GT2-3 cam at www.lingenfelter.com has a stock like idle, but perfect for blower applications. The second would be a thunder racing cam. This cam is a little more aggressive and lets you know its there. Both require valve spring upgrades. The thunder racing cam is a little more money with the springs, but it also makes more power. Sorry to hear about the troubles. I cant imagine what its like to have to wait for all of your parts to be shipped from the US or Australia. While you are in the motor, are you going to forge it? And also, if you have the blower off, now would be a good time to look into the 90mm J-tube upgrade and 90mm Throttle body. but get rid of that granetelli...

Black2003SS Posted October 18, 2007 Report Share Posted October 18, 2007 supersub...are you running the 42lb injectors? If so, I would think you are ok because you have a smaller displacement engine and a return fuel system. 04+ systems can not usually meet fuel demands for pullies under 3.0".

Vortec MAX Posted October 18, 2007 Report Share Posted October 18, 2007 wow! sorry to hear this, you may want to go up to a 370 or 408, the time is righthow many miles on this motor You won't be making a 408 with that block. You will need a new block. If you get a new one, it will be a 402 What were your fuel issues. Has it been pinging or just running lean?

Krambo Posted October 19, 2007 Report Share Posted October 19, 2007 Well, Just don't rush into anything. Think your choices through before diving in. Thank you for the pictures! Quote Link to comment Share on other sites More sharing options...
SSThunder Posted October 19, 2007 Report Share Posted October 19, 2007 Well, Just don't rush into anything. Think your choices through before diving in. Thank you for the pictures! Don't just built something new without thinking about long term goals. I dount I will ever build a bigger forged engine because it's not in my long term plan. I'll be happy to have a 12 sec SS. Right now I'll just be happy to have a SS lol Quote Link to comment Share on other sites More sharing options...

He's running the stock 38's and has had as small as a 2.8" or so pulley on it. With proper timing he's well over 120%. Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted October 19, 2007 Report Share Posted October 19, 2007 Yeah...I typed that before I noticed he is running a cam and larger J-tube. Quote Link to comment Share on other sites More sharing options...

I need an encyclopedia for all this techno garble. Are you saying that the 6.0 Radix kit comes with 38 lb/hr injectors, and that was not sufficient to feed his engine when he reduced his pulley diameter to a 2.8"? And since the injectors were being told to work at 120% of their ability, they did not supply enough fuel which made the AF mixture lean, causing the destruction of his engine? I am trying to learn something...sorry for all the Q's. I was planning on reducing my pulley diameter to 3.0" after I installed my Radix kit (still yet to be purchased). Will I have to have different injectors? What size pulley does the Radix kit come with? Mike Quote Link to comment Share on other sites More sharing options...
