Mild cams have low overlap, so it's better for turbo setup. You dont have to rev engine, just turn turbo srew.

Balance between cam, turbochargers and Torque converter is everything, but I think, cam can be pretty mild if compared to free breathing engines.



I don't know a lot about runner/valve size ratio, but free breathing exhaust must be good for turbos.

Unfortunately I don't have all the cam specs right now, he rattled off everything he was going to do and didn't right it down.  He was very knowledgeable about what to do though.  I do remember 114 lobe separation.  It will be 3,000 to 6,000 rpm cam.  I have a billet triple disc, 3,500 rpm stall converter to install at the same time.  He got all this info from me and said the cam he will build will work perfect.  I cannot wait.  It should have a nasty whole shot.  With the stall converter by the time the converter stalls the engine will be reaching it's power range and there should be a surge of heat in the exhaust and turbo should be spooled so it should a nice acceleration point.  As far as the injectors I thought that they were flooding under the high fuel pressure but we turned fuel presure down and it never fully went away.  Once I talked to Isky and he told me that the cam I had would not run right at high rpms I am hoping that was our problem.  The cam shows up beginning of December so don't worry it won't take long to install i'll let you guys know how it goes.

any new updates?

Not yet, I am still waiting for my cam from Isky.  I have my 3,500 rpm stall converter ready to go in.  I had Midwest Converter build on for my E4OD.  Has a billet back with triple disc clutch.  I can lock up under power now with no damage to converter.  As soon as I get my cam I will be back on the project.  Our chassis dyno is on its way.  It is getting shipped from Australia.  We are hoping for february.  Absolutely cannot wait.  My pickup will problably be hooked to the dyno for about two weeks straight.  Very excited!!

Hey everyone just wanted to update you on my project.  Decided to redo my fuel system.  My injectors we don't believe will be sufficient for what we want.  Plus they are a big restriction in the throttle body.  I am going to get a 2 inch spacer plate and weld in four injector bosses.  Then get four 1600cc injectors.  That way we can run higher fuel pressure and cut out the middle of the thottle body.  We will use the Commander 950 to fire the injectors, we will just batch fire them and they will be underneath throttle plates now.  Will just have to manufacture the fuel rails.  That's what's new now.

I hope your cam shows up soon! An early Christmas present would be nice! Keep us posted.

Well my cam showed up today but we decided to wait because our dyno is sitting in customs in California.  Will be here at the end of the month.  We decided to dyno my engine with the current cam and fuel injection to see the results of the different cam and turbo upgrade.  Figured everyone would enjoy some dyno results.  I am also curious what that enine will do naturally aspirated too.  Right now I have an Isky cam #F300 with fuel injection and is now running on E85.  Don't worry everyone I will have some dyno results soon and the turbo results.  I have also updated my throttle body.  Now have on a FAST EFI 1000cfm throttle body.  It is equipped with LS7 injectors that are modified to 95 lb injectors.  We will not have a problem jacking up the fuel pressure now either.  It also opened up the top of the throttle body so there will be no restriction from the fuel injectors like the precious one.  Can't wait to get you all some results.

Any news or updates?

Dyno showed up late friday.  I couldn't take it I pulled my engine and installed the new cam.  I also installed my new high stall converter.  I got a chance to take a peak in my engine and was amazed at how clean E85 burns.  My valves are spotless and tops of my pistons are nice and clean.  I had to order some new titanium header wrap so that should be here tomorow.  I will take pics of the completed project and post them tomorow.  Chris will be up from Kentucky on friday and saturday to train us on the dyno.  By the end of the weekend I should have some dyno sheets on my turbocharged y-block.  Cannot wait. 

When you,re using that aussie dyno, better turn it rightside up!!
