nice score EZ! i luv the bigger cap over stock. unilite's are recurved so no vac cannister, gives it a cleaner lookThumbs Up

i had no issues with it in my '67 nova but this is what i've learned from others who burnt out their unilites unintentionally and/or prematurely:
never jump-start another vehicle or receive a jump-start.
never MIG weld your car with the battery cables connected.
never work on ANY electrical with the cables connected risking a short to ground.
a high output alt will add more stress on an already aged-old wiring system and all circuits.

ALL of the above could have been avoided had they installed a Voltage Stabilizer (no, not those cheapy ones) to prevent voltage spikes/surges.
also, ALWAYS use a Mallory ballast resistor. i worked on a friend's '70 Boss that had a no-start/no fire issue. turned out to be a ballast resistor that had a broken spring!






disclaimer:not all of you may agree with the above but hopefully someone will learn from my experience. peace.

So EZ      WHAT are you putting this dizzy on?   Or did you buy it to mount on the wall and drool at lol.  I bet rusty would trade a case of Dr. Pepper for it.

Ah I see,   well it has to be an L or an LZ and its definitely a 4  not a 6er because I know you dont own a Zcar.   Whatever this mystery is it had better be at the car show!

You're right I don't have a z, that mallory is specifically made for the 4 cylinder L-series timing rod and cover! I guess I could make it the opposite of how those old 198 buick v-6 engines were made... lol, anyone know what I'm talking about??? Honestly, it's nothing that hasn't been built before, but I'll call it a little more "traditional"    I just hope that I get potter paid off!!!

EZ, if u are building what i think it is then u better be using a SD22 crank, napz22 rods, AMPco dished pistons, twincam OSG head with twin MOFO turbos. Did u find the matching gear u needed for the Unilite to spin the turbo oil pump drive? U may have to machine 2 at your shop with straight cut gears but then your motor is gonna sound like a V8 with a loud gear driveApprove

Yeah, found the missing gear... it fell half-way down a keyed shaft that was able to get to by removing the oil pump... lawl!

I want a hit-and-miss l20b!!!!!!

on 1st fire up u will need to hold it at 8-10k rpm's for 5 minutes, unlike a traditional break-in period, then every 5 minutes for 20 minutes then u are done. in between those 5 minutes check the glass windows on the OSG head to be sure u see a nice blue color. if u had pre-mixed enough fuel with CH3,ch2,ch5 ( moonshine) and  C54H100O7 (veggie oil) then it will burn blue. on 1st launch u will see a reddish orange glow exiting the exhaust but the afterburners will soon turn it into a glowing blue flame after exhaust temps and back pressure stabilizes and you'll notice an occasional green flash (eco waste) from the boosters. fuel tank pressure should be no more than 163psi.also, re-check the o-rings in the fuel bilge pump.
an L20/SD22 is simple to tune but occasionally u will need to re-set the launch codes while maintaining cruise speeds on long flat roadways.
