Hey everyone got it fired up. Thanks for the heads John they really move some air.  I can tell from the extra fuel I had to add to my map.  The turbo is also bigger but my compression is under control now.  We are able to tune the engine much easier now at proper air fuel ratios.  Although I found that I am going to have to upgrade my fuel supply system.  At about 4,000 rpm it was going lean and I could not add enough fuel.  Chris watched the fuel pressure gauge and it falls to around 0 at WOT under boost.  I ordered a bigger fuel pump and I am going to tap a new fuel feed from the tank.  I am still using the original fuel line from the tank that is only 5/16 line.  I think I may be starving my pump.  My current Holley in-line fuel pump is rated for 500 hp with forced induction, subtract about 30-40% off of that for E85 and I  may just be at its limit also.  I ordered a Aeromotive A1000 that should support up to 1,200 hp forced induction.  I am also going to enlarge all my fuel lines for more volume.  I was tuning it a 8lb's of boost (same as with the previous heads and turbo) and the engine ramped up to 375 wheel horsepower and 495 lb/ft of torque at 3,750 rpm before it started to run out of fuel and go lean.  I am looking forward to getting up to 6,000 rpm under boost.  Once I get my new fuel system we will turn up the boost to 15 psi right away.  My engine is a lot happier now with lower compression.  Thanks again to John those heads are bad ass!!

That was a piston from a previous misshap about a year ago  John those heads are gonna be nasty they look great.  I have them bolted down and the engine back together already.  Thanks a bunch!  Might be fired up tomorow.  Here is a look at my new turbo.  I might just sleep with it under my pillow tonight it's perty sexy.  This baby is gonna hit hard.  It will be one angry y-block!!!

One to the left is the old one.  New turbo is a S366 Borg Warner which will support up to 800hp.  It breathes!!!

Robi, it looks like you need to check your deck clearance. That old piston looks like it's been gettin' intimate with the head!

A little thicker head gasket might help it.

-471 Heads should be there very soon.

Should be a beast!

What a waste . Good pop ups milled to nothing!  No, I hope that you get the engine running ok and you will break that 800 hp barrier soon .

I got my pistons back from being milled down and put back in my engine.  They look great and should make a much better combustion chamber.  My heads should be here hopefully monday.  I also ordered a Borg Warner S3008SX-66 turbo charger which will support up to 800 whp.  Should not run out of air this time.  Should have it back together by end of the week.  My old head gaskets also showed no signs of compression leakage what so ever.  They had about 1200 miles on them with 8-10 lbs of boost.  Will update on any progress.

I am not sure exactly what thickness I would need.  I would guess whatever a crushed gasket thickness would be.  Have you used any yet?  Do they require more torque and seal good?

We can deliver plates for you. Just tell us how thick you want. Our first test for those plates will be at the end of June, cause our new bottom end has had some delays. So, we have no experience yet.

Wondering if the Hollow Heads could get some copper gaskets?  John is almost done with my heads.  If you have some cut I will buy them if not there is a shop in town with a cnc machine to cut them but if you could get me some that would be great.  Have you used many of them yet and how have they held up?

here is the info on copper headgaskets.

Copper head gaskets were advertised in YBM about a year or so ago. Maybe someone here can zero in on what issue?
