The heads look awesome, and we can't wait to see how The Isky cam runs that was installed and degreed today, and dialed in to a 104 I.C.

We will be mocking up a head and checking for piston to valve clearance tomorrow with clay to make sure the new cam doesn't slam the valves into the pistons; fingers crossed.

How much lift do you have now? Iíll bet even on the tighter lsa youíll still have a mile.

Lift is in the low .600's on intake and exhaust with a 1.7 rocker...

We checked the Piston to Valve clearance today and it wasn't nearly as much room as before, as it had about .140 clearance on the exhaust side this time.

Yes, all will be fine....

We torqued the heads up tonight and took some measurements for the intake manifold machine work still to come.

Everything is looking good and going back together very well.

Going to clean the new 1.7:1 HS rocker arms in Mineral Spirits, dry them well, then soak them in oil and start checking for pushrod length tomorrow if we get time.

We got it all back together today....

Here are teaser picks of the intake porting work by Eric and Mark at Vortecpro.

Aside from the awesome port work, what you canít see is the 5 lbs of aluminum that had to be removed from the intake to make it fit the heads. This was a rough-finished Intake, and I know what the before and after looks like, and there was literally pounds of aluminum removed from the gasket faces to make this intake fit with true precision!

Next week, maybe Dyno testing of the new upgrades!

Nice
The heads look like they will deliver as does the intake.
Mark does top shelf work.
I'm looking forward to your new dyno numbers.
Thanks for sharing

Dyno Data Today!

Thanks again to Vortecpro for his huge effort on this project with my Dad and I.

This is going to make a very nice Street/Strip combo for us, and we canít wait to finish the car and make some runs.

Also, I meant to get a picture of all of us standing with Harold Bettes, who was there most of the day, but we were so busy making horsepower and talking engines that I forgot to do so.

Harold was there to hang out with us and to share some of his knowledge with us and answer some questions I had, as well as to watch an Olds engine pass a pretty good number.

Mark says there is still more in it with with an improved distributor and a little more fuel curve refinement, and Mark and Harold suggested longer collectors would likely add more power.

All in all, we started at 8:30 this morning, and got done at 7:15 tonight, it was a long day filled with hearing an Olds grunting out some good power, with lots of little corrections to all add up.

How much HP&TQ was left on the table because of the dated piston and ring package?
Not that the engine needs anymore!!!

I would bet we could have seen another 15 +HP with a modern piston and ring package. Also, Locking out the distributor and upgrading to a crank trigger could have added another 5-10hp more.

Adding longer header collector extensions might add another 5-10hp.

Shimming the hydraulic lifters to convert them to be ďsolidĒ might add another 10hp.


So, moving forward, we might still modify the lifters in the future, we are already going to change to a Holley dual-sync distributor when we switch to fuel injection, and we will likely play with the header extensions at the track for the fastest times when we install an exhaust system and cutouts possibly.

We may be able to add 20-30hp more to the combo, especially if we can get a good tune with E85 vs. 91 octane pump gas the engine ran the numbers on the dyno with.

We wonít be changing pistons in the foreseeable future.

But youíll most likely lose some peak power with EFI, apples to apples.

I was thinking it will be the same or better with EFI, especially with an injector plate below the throttle body to introduce fuel to the plenum instead of installing bungs and making it a true MPFI. I think EFI will shine because I can tune it for all fuel types, using the same injectors. I figured I could increase the fuel pressure to 60psi or more if needed to get the target lambda with E85 using these Green Giant injectors.

Any way you want to look at it, the power you had is enough for a low 10 sec driver in Florida @ 3700 pounds. Goal met. The nice thing about dyno testing on my dyno is the numbers mean this:

127 MPH @ 3700 pounds = 584 crankshaft HP
1320/127 = 10.39 ET

Didnít realize you were doing it that way. You might retain more hp that way vs a carb but you lose the cyl to cyl balance. 6 of one, half dozen of another I guess.
BUT your infinite timing control with EFI will give you as much of a benefit as any other feature.

Before we changed to the Ported Batten intake and hugely improved heads, there was quite a bit more cylinder to cylinder variation on the spark plug readings.

With the intake and a "wet-flow-plenum" fuel injector setup, I think we will be in good shape on the air-fuel variations of the tune, especially with fully graphed spark control for all possible map conditions.

This is getting way out of hand. Might have to call Homeland Security to keep this rocket from causing irreparable damage to the motherland!

Yep, hoping to rotate some Earth at a high rate of speed with this car!
