I don't believe so. It's mostly LS3 or Gen4 type engines and they run off an E67 PCM.

There are plenty of builders that sell Gen 3 based engines though. SDPC put one together for me with all new factory parts at a reasonable price.

 

Exxon/Mobil= don't plan on going wild with anything, down to pretty much replacing my 150k LM7 with something with a little more oooomph..........

 

Exxon/Mobil is what we have found to deliver the best mileage until I ran a couple of tanks of Chevron. Picked up over 1 mpg and probably 2 when running the numbers is done. Check it out if they're in your area.

 

Hmm- thanks for the heads up, swath- gonna be checkin' that out......

 

OK- brushed up on my math, if all is right and starting out with Advanced induction 226cc heads with 69cc chambers and head gasket thickness of .075 and bore of 4.060 would yield 9.78:1 compression should be looking at DCR 8.32 and cranking pressure 168.22psi with IVC 55.5*. BTW- with this different gasket thickness (I understand the originals are .052) would I need different pushrods.........

 

Of course you will need different pushrods! You will have to measure when you put it together though in order to figure out what will work best.

 

Are you running an LQ9 flat top or an LQ4 dish piston?

That makes a huge difference in the compression ratio?

 

LQ4 dish. 10-4 on the push rods, guess I'll be investing in a PU length checker- any recommendations............

 

 

Now that we know what your doing we can get a more accurate picture.

IIRC an LQ4 piston has an 8cc dish.

1st, Why bore the engine .060 over??? There is no advantage to that and the engine will actually run hotter the thinner the cylinders get.

2nd, Why .075 thick gasket? This will take away from the quench area and reduce compression lower to like around 9.2:1. Typically the factory pistons stick out of the hole on these Iron blocks. Each one is a little different I typically use .006 out of the hole for rough calculations. Ideally you would want to run around a .040 quench which is why the factory uses a .052 thickness gasket.

If you want a 9.7:1 ratio I would build an LQ4 with a .020 over bore with a factory head gasket and 69cc head.

I have a comp cams pushrod length checker 7702-1
