Part Deux:
Now the trails that are local to Matt are mixed dirt bike stuff, and some just plain ol dirt roads, and a few good sandy washes thrown in there.
We head up the way to this makeshift old track we’ve been on actually a bunch playing around with his truck. It has some jumps and a decent whoop section. Lots of hardpack and square edged bumps. I cruise around chasing him on this track, trying to not be too aggressive but still having fun, kicking the back end out on the berms and such. Trying to loft the front over some of the lips out there, it was pretty cool aside my rear shocks being stiff and making it a bit uncomfortable. The front could care less. I did manage to get airbone on a small table top that was there in a rythm section. That I actually backsided which felt really cool in a truck! Really makes me want to take this to Elsinore or Glen Helen on their short course track!
We left from there and headed back out into the open desert and proceeded to haul a$$ down as many open roads as we could find, we found ourselves in some single track(read:single truck wide) and in the switch backs, in a trail both us had been on before so we started to honk it on, and I swear if he would’ve checked up or stabbed the brakes I may have hit him... but he didn’t and we kept up a comfortable pace that really felt good in Lucy.. the turn in response and how stable and planted this feels is crazy..
the truck just eats up these bumps and whoops like they don’t exist, it’s like you brace for something that you initially assume is going to cause a bang, and nothing.. just nothing happens.. if it’s big enough it’ll kick the back just a tiny bit.. orherwise keep your foot down.. and drive!!!
Reminded me some of a long autocross mixed with some Road course increasing radius turns that are flat out and tighten at the end.. super fun, you can back it in, and throttle out.
It was a good day guys... a dang good day..
It started to get dark and I have no lights at all and we headed back. I shot the stuff with Matt before I loaded up and left, mulled some ideas to bandaid the back for now so the next trip I can play with the bypasses some to make the most of the limited travel I do have.. otherwise the trip was a success!

Thats exactly how nate's truck is. You brace your self for ouch, but it just floats. Then you realize those are 3 foot whoops and the faster you go the smoother it got. So awesome.
Super counter intuitive!! Lol but I figured driving it like I rode my dirt bike worked pretty dang well.. that cross translated damn near exactly.. pretty happy about that because it makes me not miss dirt bikes lol..
Looks good Steve. What’s your ignition timing at?
Sounds retarded to me in the videos.

It’s 32 total and it’s 16 initial. I am gonna lock it out when I swap the distributor. Prob close to 40 total when I do that.. or whatever it’ll take
I was going to PM him the same thing, and then I saw your message and at first I thought you were teasing me from my previous post. I was going to say just because you can't hear it doesn't mean it isn't true.
But after Steve's post now I am thinking you agree, ha haHow much vacuum do you make it idle? If you don't have enough vacuum for a vacuum can then I agree, lock it at ~38 or whatever it likes, and it will be way more responsive and feel and sound stronger. If you have enough vacuum for an advance can (~10 inHg or more with the correct can), then you can run a can but it takes more work to get the curve right. You can set the base at about 20 and then ramp it up to 38 by 3K (light springs) and then set the vacuum can to add another 14 on top of that but make sure its all in at idle too(the can has to be all in by your idle vacuum or its the wrong can). Although right now it would probably run a lot better if you just advance it another 4 - 6 degrees everywhere, unless your converter is too tight for the can, then you might not get away with that or locking it out because it might ping down low.
The jump was cool in the go fast thread, you can see the suspension working good. I really liked that!
Well 16 btdc initial certainly isn’t retarded by any means. I don’t know your build specs on Lucy’s engine but have you verified the timing marks at tdc physically? Not saying you specifically, but I’ve seen guys (me) swear by their timing, only to find out later the balancer mark was not correct. Hence showing 12* btdc but actually 2 or so.
Lucy looks awesome out there btw...

I had it apart and it’s correct at tdc, i double checked it with the timing cover and painted it. The specs are a normal 9:1 357 balanced with flat tops and 5cc reliefs, crappy 882 heads with a steel gasket .015 compressed and the piston was .032 in the hole. The cam is a comp XE274h which puts me at a dismal 7:1 dcr. The intake is a performer rpm airgap and topped with a Holley 700dp modified with a third circuit.
The distributor is off something that I have no idea about but the mechicanical adv is stopped at 16 total degrees of swing.
I have a pro billet without the vac adv can but I might keep this and do what heath suggested, it needs way more timing down low. It’s kinda lazy which I expected but when it’s on the pipe whatch out.. it hates the dirt and the 5:14 does nothing but make the lack of traction worse.
No no you are right... it needs turbos, efi, links in back, bumps, bypasses and more cage.. then I will be done.. until then.. I’ll tale donations.
Haha, he said done. Lol
Tail donations?
It’s all perspective! Done as in that version done..
I don’t even know what that means
You can lock a std old HEI dist, just remove the rotor and weight, phase the rotor, then tack weld the two plates together so there is no mechanical advance, then put the rotor back on. If you use a slotted plate/tab and a couple screws to lockout the vacuum advance you can make the little magnetic pickup adjustable somewhat for rotor phasing.
To phase the rotor close just align the rotor so it is just starting to contact a plug terminal in the cap when the magnetic pickup is stuck on itself (triggered). Of course holes in the cap to check this would be even better if you have an old cap. You can make minor adjustments by adjusting the magnetic pickup collar where the advance can used to hold it.
But if your cam is only [email protected] you can probably run a vacuum can.

I’m gonna yank this out and check the bushings to see if they are any good or not and replace it before I mod it.
Yes so.. I did a thing.. the fk it was strong last night..
