Happy 50th Buddy!!!

See, I know a certain 'someone', that pulled consistent 12.2's/12.3's in the quarter... with a cam much milder than this one. I 'spect Phleb will have plenty of fun with it

Yes. The LSA was widened to 112 (and that chart is based on 1.6 rockers). Should make for a pretty snarly 350

For what its worth...

That'll be quite enough guy's. Play nice or don't play.

De-greased the slimy bugger... BRAAP donated the only structurally straight parts car on the property, a '75 (thanks!). Dropped in the S52 and gearbox, and bolted up the trans mount. Fits well, mostly... Heater lines look workable... Oil pan is going to clear... With the front of the motor sitting on the steering rack, I rigged up an adjustable mag-base and laser pointer. Spun the output shaft by hand and adjusted the base until the circle became small enough to be useful... Prognoses?... The laser intersects the pinion flange about 1 5/8" too low, and the digital level says the diff and engine are within one-tenth of a degree of each other. Not only does the front of the motor need to come down, so does the nose of the diff.

Rule #7...

Creating (and using) grip, longitudinally and laterally, will stress the chassis more than a specific engine will.

You're contradicting yourself. Your last post is an act of defense after I asked to put it back on track. Last warning.

Lets get back to the technical side of this discussion, please.

Congrats Yeah, that post got deleted. I'll add that note to the sticky...

It a standard model V4+. It would require the plug-in adapter to work with the RB. I PM'd you the email address of the fellow that owns it.

Oooooohhhhhhh... shiny bits..... Time for my happy nap.

Yes, open loop. V4X is a newer release, odd as it sounds. It will run a 6 or 8 in a 'wasted' configuration, but it specifically target's the 4cyl market.

That ended with V4. V500 has two switchable mapping systems, built in. I might know where there is a well cared for V4+ system for sale, and the 'cards' are still available. Want me to check on it?

Wolf3D can fill that bill. Technically, Wolf datalogs. However, I'm not crazy about it. A bit clunky in my opinion. To Wolf's credit, it's *always* logging... you capture data 30 seconds before you hit "record".

Websites? It seems like most every consumer product produced & advertised has become a bad circus act.

You're killing me

With the drivetrain sitting in the '77, it was clear the tranny needed to sit as high as possible. For giggles, I stuffed a stock Datsun mount under the trans, and found it to be a near perfect fit. Only needing to trim some of the flange off the front side, re-weld the flange at the cut, drill two holes for the fasteners, and a little massaging of the surrounding bolt hole area with a press (to provide enough flat area for the bottom washers to rest against). Took longer to clean and paint than to modify... This location puts the tranny about as high as practical, with the height of the output shaft about 1/8" lower than stock, and the motor longitudinally within an 1/8" of of the pictures above. If the rest of the swap was this easy, I'd have it done in a couple of weeks

Here's a silly example... A. Assume no tire slip. B. Assume same size, non-vented brake rotors front and rear. And they weigh 50lbs each C. Assume no brake pads (keeping it simple for this example) Run the car at a dragstrip, with the front rotors removed, but the rears installed. Run the car again with the front rotors installed, but the rears removed. What do you get? The same exact timeslip. Put the same car on a static dyno, same two scenarios, and the HP numbers will show the exactly same regardless of where the rotors are mounted, just like the dragstrip confirmed. Just like the real world. Put the same car on an inertia dyno, same two scenarios, and the HP numbers will show higher with the rotors on the front, and lower when they are installed on the back. Funny, since the car ran the same 1/4 mile time. The point is, inertia dyno's can be deceptive, especially to those young men that think installing a lighter wheel produces more power because the inertia dyno said so. They gained acceleration, not power. They reduced inertial losses, not drivetrain losses.

MAG is plainly correct. Put your car on a static dyno and measure power at a specific RPM. No driveshaft material will change that number. The inertia of a wheels, brake rotors, driveshaft, flywheel, etc, etc, will influence acceleration, but not power. They are not part of a drivetrain loss calculation. Friction is.

It doesn't matter right now. You're car will run fine on any fueling order. Later, when you put the car on a dyno, you can bump those numbers up or down and select the sequence for best power. It will normally be a modest gain... too small to feel in most cases. If the sequence was grossly out, you'll likely see a slight improvement in idle quality, as well.

Now that one I knew... just forgot

I learn something new every day

To my knowledge, all S30 VIN's begin with HS30 or HLS30 (L = left hand drive).
