Installed a thermostat (P.O. had taken it out, not sure why).
Installed a mechanical coolant gauge. I have been having an issue of getting hot in traffic.
Installed 2 9" fans to help with the cooling issue.
Did a test run (idled in the driveway). Got it up to temperature (160F). Thermostat opened. Slowly climbed to 170F and I turned the fans on to see how they worked. The temperature went down from 170F to 155F in seconds. So at least those work. I am going to install a temperature switch so the fans will come on automatically, but I have no idea where to install it.

These will replace my 38mm SU's.
Cool , assuming they’re 42s
did you get them from John Parker ?
Yes indeed! These will get installed after I sort out an electrical issue that is popping my 20a main fuse. I believe I've tracked it to a faulty regulator in the alternator. And yes, they are 42mm. I plan on retaining my stock fuel line, choke cables, throttle linkage, and also figuring out how to use my fuel return line as well (that one may be a bit tricky).

I also installed a couple electric fans on the radiator and a temperature switch to control them was installed in the radiator hose between the thermostat housing and the top radiator inlet. Do a search for radiator hose temperature sensor. Lots to choose from. And be sure to get the temperature switch that closes at 180 (powers the fans through a relay) and opens at 160. You can also install a bypass switch to manually turn on the fans whenever you like. Also, some picture of my install are in this "What did you do to your 510 today" at page 95.

Finished installing my modified cup holder gauge pod!

Had to modify - via file and dremel - some of the bolts/washers for clearance.

Need to move the unit forward just a smidge...like .5" or so.

L20b
- twin 38mm SU's
- domed pistons (280zx Euro spec)
- A87 open chambered head, port matched
- Mallory distributor
- 4-2-1 cast iron header
- mechanical fuel pump

Last dyno'd at 110Hp / 132Tq

Remember, my vehicle is running at altitude (~5,550 ft above sea level)

Jetted as follows:
- 190 Main Jet
- Y6 Needle Jet
- 22.5 Pilot Jet
- 2.3 Float Bowl Needle and Seat
- Jet Needle Raised on Notch

Now, I'm not sure yet what all that means. I've got an extra jet set of jets on hand, in case they need to be adjusted. I'm hoping John's expertise results in a good setup that doesn't need adjustment anytime soon.

John knows his stuff and is usually pretty good at being in the right ballpark right of the bat from what I understand, I wanted to see your jetting to compare to what he will provide me when I order for my 2.3 stroker.

as an FYI I did install my 45s on the L28 last week and it was a breeze to install , we got them on the car in minutes and they ran smoothly right away (see video) They sound awesome and are super responsive.

I havent done some fine tuning yet but should be doing that this week now that my wideband is installed and hopefully getting the car on dyno next week. I'm in Quebec so the car will not be on the road for a least another 2 months before I can give driving impressions.

I got it started, and now have a few issues to sort. Needs a tune but nice to hear it.

I wandered over to my daughters garage yesterday, to do my March fire up.

If you can imagine, the passenger side is right up against the garage wall, and yesterday, when I opened the garage door, my son-in-law had 2 kayaks jammed on the drivers side, against his trailer, but, leaving me hardly any space to open my drivers door.

I carefully squeezed in, which was a bit of a chore, snuggled into the seat, armed a few things, fuel pump on and cranked the motor...no fire....crank again..no fire......

Then, it hit me, I had taken the plug wires off last time to allow for my engine warming light to be there..

Squeeze my way back out, wires on...back in the car...whammo...engine lights.

Only one more fire up to begin the driving season for me. Will be interesting to see what Avgas is this season, the last price was 1.95 / litre, so it will be well over 2 bucks by the time I need a refill of my drum.

Replaced my mechanical oil pressure line per Keith’s recommendation, thank you. The old nylon line was very brittle.

My son and I also drove up to Sonoma Raceway to watch vintage racing.

Thanks, now I need to protect my wagon too and replace the nylon tubing.

Is that an early roadster filter assembly or a DRP reproduction ?

It’s the later roadster solid style with the holes. I trimmed it down to make it look like the earlier version.

finally got around to doing my alignment .. only took me a year to do so😎

bought turn plates and caster guage last year and yesterday spent 4 hours doing it..showing apprentice how everything is adjusted.
got 4.4 degrees caster and now fenders will need a trim / roll to pull more forward.
for now it's at that 1.8 camber and 1/8 toe in.. drove significantly better than pre alignment..
