    Thanks! Those part numbers will help a ton

    Gotcha, and I’ve seen that you can use ls springs to achieve more lift, while leaving the heads on and doing no machine work, do you think that would be the way to go?

    Should I pull the heads and do valve work to allow for more lift? Or are there cam options with only .45 lift that will still let me take advantage of the heads

    Awful gas milage.

    It’s a 70s smog short block with vortec heads, so yea shit cam lol. But no I spoke with msd and they said that aslong as I have a good coil and cdi, which I do, I can use a light if I know how and get it just as good as the atomic

    Awful gas milage.

    Exactly the setup I’ve got, I just haven’t swapped my 3.73 rear end in yet, I’m running the msd atomic, and I already have the heads, but with a lame stock cam. What kind of differences did you get from the cam?

    Electric fan conversion

    Just a look at my relays, all are 40 amps, but the two smaller ones are getting wired in parallel this afternoon to effectively make a single 80 amp for the high speed

    Electric fan conversion

    Dude is that a baking sheet! I’m trying to mock-up mounts with strips of metal stock and sheet metal but if it doesn’t work out, I’m defiantly going that route

    Electric fan conversion

    I’ve actually got a few 40 amp relays laying around, one will handle the low speed, and then 2 more will be wired in parallel to handle the high, effectively making an 80 amp relay since they share the load. And my msd efi system has trigger wires for a 2 speed fan to control it at whatever...

    Electric fan conversion

    Yeah I’m running a 110 amp alternator from some early 90s truck that still ran a vbelt, I have lots of things drawing from it and still see 13.5 volts at all times

    Electric fan conversion

    The Az heat has led to my clutch fan locking up after 10 minutes of driving every day this week, and I’m done sounding like a Mac truck and feeling all that drag in the pedal. So I’m finally pulling the trigger on a long planned electric fan conversion. Today I ripped out the stock fan and...

    REALLY? I’ve always heard it’s the way to go for full tun-ability, not the case?

    Honestly if you go fuel injection I’m starting to think I should’ve gone with a factory tbi setup, and built that out. Or the Holley sniper, you have WAY more control over those sniper units. But for simplicity you can’t beat the msd atomic

    Which do you run? And by drive do you mean 3rd gear? Because I drop it in 3rd on the highway and at 80 I run in the area of 2800 rpm, and it likes it a lot, I got a lockup kit today, hopefully that, my soon to come electric fan conversion, a shift kit, and my coming 3.73 instal will help a lot

    Help upgrading the AC on a 1985 C20 6.2L

    For inspiration I daily drive my 78 here in Phoenix, and I have no problem even in scorching heat, I rebuilt my ac with all stock parts and a 134a conversion kit and I get 40 degrees all day, some tint and insulation are used to keep it all in, but other than that I have 0 issues in the brutal...

    I have initial at 14ish, but I’ve gotta put some tape on the balancer to find total

    ALSO, I absolutely SCORED yesterday, I bought an open 3.73 axle from a 77 for 150! I popped the cover to confirm and check out the gears, and everything looks healthy, it’ll get cleaned up and put in very soon

    This is EXACTLY what I’ve been looking for, I should actually have everything I need besides the wires under the pan, so I’ll be going to a yard soon to grab those. Thanks a ton!

    No, the fi kit is basically a throttle body with an 02 sensor and temp sensor, everything else is built into the unit. Other than that it’s a carbed vortec 350

    Right now I see mid 14s, every now and then the afr dips up to 15, depends on my foot

    I’ll have to give him a call and ask a few quotations then.. and I’m running a rad cooler plus an external, so hopefully it’s not 100% cooked. And I’m in luck! It was factory cruise so the switch is still there, I’ll try to drop the pan and wire it up tomorrow morning, I’ll run a manual switch...

    Awful gas milage.

    The truck is a turbo 350 truck, but the trans was pulled from an 89 and I swapped it in. There is 0 wiring in the truck for lockup, but I pulled the pan before install and DID see the solenoid, just with 2 clipped wires... and the converter is the stock one so it should be lockup. I can just...

    So you’re saying that even though engine rpm is low, I have to compensate with lack of power with throttle, makes sense. I’ve been looking around for axles on Craigslist but they’re all junk 3.08s like mine. I’ve got a quote I like, so 3.73s are going in soon. And while I don’t have the money or...

    It is advertised to be self learning, and I can tune the target airfuel ratios, and if I bought an msd distributor setup I could do timing control with it too, but I’ll stick to my cheap cdi and timing light for now. It’s taken me a long time to get here but even back when I had a turbo 350...

    To the trucks credit, the 2.5 inch dual exhaust makes for plenty of those!
