Default Re: A 30 year journey, and a 2nd chance.

I was right, but I needed that 10 mins help for sure, and the next day it was finally under index on that first pass, and I was actually short shifting 1/2 for a reason and running out 2/3 (sometimes right up against the rev limit feature of the ECM to make sure it was consistent in it's application, mainly because the engine is still pulling hard when it comes up to that set ECM programming I can only turn on/off it cannot be changed higher or lower at this point (the ECM is locked, are only tables you can view, and flags are 0/1 (off or set on) (Class Racing in 2 days).

The timing really needed to go 3 degrees total higher I believe, but it was beyond drivable and later showed pretty good consistency (as long as it was driven consistently, and small changes netted small gains, and there was still some speed never shown (so I left it alone), & do not underestimate my Slow Ride...I'm just taking it Easy! ~</;-)~

For Now!

(This is on a rebuilt engine that never saw 5,700 RPM throughout the first almost 93K miles in any gear but 3rd 6,200 at the lights, and after balancing, etc. is running hard up to 7,300 RPM and still pulling hard. But, I will not run it without that rev limit feature on...A Holley ECU and custom harness to my sensors will allow resetting it higher...1 of this Winters projects ahead. LODRS 71 at Las Vegas in November first!)

In the end...60' 2.85, down to 2.35 (exactly 1/2 second). so, the cam choice was not just a lot better at this point in time...It was dead necessary!

Winter will see the Transaxle dropped, fully freshened (those clutches etc. are factory 1984), and the Converter loosened along with those other changes mentioned earlier.

John & Jon, sorry as I know you were getting worried for me, but I was methodically working through undoing changes, checking everything 1 by 1, leaving what was working, and deleting/reversing what wasn't, while making big Timing swings just seeing which direction the new cam liked (and we found it together in 10 mins with your help). It is why I purchased that extra test day.

It often sounds great sitting still, but under a 2,800 + lb load pulling (a low 99 HP powerplant can act very differently when you step on it), The cam once timed correctly, and an injector back into the Rich/Lean sweet spot, cleaned the plugs right up, brought the bottom end back, and the top end was quite sufficient also, and restored my power brakes to holding 3,800 RPM foot braking consistently. (Power Assist Brake Booster was even holding between starts w/ no losses of vacuum). And it never failed to start, though it cranks hard w/ that much initial and total timing, it has a 90 Amp Alt. on it and a new battery and a live LED minder gauge w/ 2 USB Phone/Tablet charging ports. So, I can see from inside the car or out, the charge state of my battery at a quick glance at any time!

Like I said earlier. I will tone down the novel now, and just pretty much cover build changes to the car from here on out, and good news results if those arrive, but I wanted to go into a lot of details on the Re-debut that I will not later. Thank's for reading. (Floods to LED Tree is a biiiig change folks!)

Older guys know what I mean for sure.

Mark YAC....I am not yet where you are my brother, but I will be by Spring! I will get you those 2 pcs this week, my old Power Brake Booster, and Old Master Cyl, as soon as I find out for sure that my intended replacement Master bolt centers are exactly the same or not. I will know by end of next week I hope.
