    Gear and tire height spreadsheet calc.

    Should I add in a slot for transfer case gearing? I'm a 2wd guy myself so I never really think of transfer cases. Could also double for those curious about gear vendors ratios too.

    thoughts on an old 2 ton truck

    Do other states not have permanent plates? In Montana if it's older than I think 11 years you can throw permanent plates on it. I think it was about 300 to get permanent plates for my truck.

    Edelbrock heads, worth it?

    No blower, the guy was selling these heads because he decided to change to a blower setup.

    Edelbrock heads, worth it?

    Thanks guys. I knew it wouldn't be an ideal combo and the drop in compression would hurt. I just wanted to make sure the other factors wouldn't be enough to make them still worth while (better flow, better chamber design). Some people really talk down the early closed chamber heads so I thought...

    (Seems Like) A Good Price for a Lift

    Damn, I want one. I always assumed it would be more too.

    Edelbrock heads, worth it?

    Yeah, I'm leaning towards the drop in compression being too much for me to spring for them atm. It's my daily driver, it does see some light work occasionally but it probably won't be pulling anything heavier than 4000 pounds for quite awhile. Overall it gets driven more like a hot rod than a...

    Edelbrock heads, worth it?

    Alright, I found a set of supposedly barely used edelbrock performer heads on craigslist for $900. Called the guy he's throwing on an 871 blower and needed lower compression, hence selling these off. Now unfortunately they are the 110 cc chambers so it would kill my compression. I currently have...

    Hi guys :)

    I have dreams of a gear vendors myself, or maybe a 4l80e. Secretly I want both for 8 forward gears and the ability to run a stupid deep rear and still cruise without a care, but that's a pricey dream. I have a fairly similar setup myself, 800 quad, edelbrock performer, long tube headers, and a...

    Hi guys :)

    Then you'll be plenty fine, just wanted to make sure you weren't expecting a highway cruiser with that combo. 4.11 would be great for work and hauling.

    Hi guys :)

    Hey, more Montana is good. I'm in Butte for school atm myself. 3700 rpm is a hell of alott for cruising. The 6k isn't intended for cruising rpms, that's more like a shift point if you're power shifting. In general any max rpm you read about is for brief periods just before you grab another...

    Lol, oops. Didn't catch that, I just copied what they wrote.

    https://greatfalls.craigslist.org/cto/d/1885-chevy-c3500/6463015855.html 58000 miles for $3200, if I had the money and space I'd be very tempted

    What did you replace factory radio with?

    That said I'm not an audio guy so I'm not the most informed on this kind of stuff.

    What did you replace factory radio with?

    I have the base model retrosound. I love it, perfect for my needs. Now all it has is aux and am/fm. I just use an aux cable and play music on my phone and it sounds good to me. The port is on the back of the radio but you can mount a port anywhere you like. Although with modern phones shedding...

    throttle spacer, air gap, or...

    Shit, I'm sorry. My info is mostly from when I researched manifolds for my 454. The bbc performer rpm has the joined plenum. I assumed the sbc manifolds would be the same way. It looks like with sbc only the air gap performer rpm has the joined plenum. The main reason I suggested the performer...

    throttle spacer, air gap, or...

    Think there is a bit of confusion over "air gap". Edelbrock kinda set the nomenclature with their air gap manifolds, they have space between the plenum and the valley to reduce heat soaking into your intake charge. I think what you're looking for is a space in the divider between sides. The...

    Leaf Spring Bushings

    Get the black ones, they are have graphite to help. Then just lube them well and you're set.

    Stepside fuel filler question

    I believe right and left are the same. The tanks are the same, regardless of bed or side. Only thing is a short bed can't fit the 20 gallon tanks, they're too long. Now my neighbor who is an old-school mechanic suggested the local Ford dealership for the filler necks. He told me they have...

    Imaginary Engine Build

    1. I don't believe rocker ratio would change rpm range in a noticeable way. Just use a good valve train because you're adding more force to everything involved. 2. I think vortec heads would work well with that cam. Iirc vortec heads flow best at mild lift numbers, pushing past .500 lift and...

    Hesitation - 400 sbc 850cfm 4-Quadrajet

    I highly doubt it's actually 850cfm. The only change they claim is a bigger needle and seat, and that wouldn't change cfm at all. Honestly I couldn't even find their supposed reman company "Topspeed". If it were me I'd verify that it's an 800 cfm casting and not a 750. Hopefully it's legit for...

    Need better fuel mileage

    Mine is an 81 c2500 with 454, th400, and 3.73 at the time. I got 11-12 with everything stock except a set of headers and the timing advanced to about 12° initial (factory spec was 4° iirc). Now I was a dumb teen so I wasn't exactly lite footed.

    Hesitation - 400 sbc 850cfm 4-Quadrajet

    X2 on accelerator pump. You can turn the linkage and look down the primaries to check for the squirt. (Running or not, long as there is fuel in the float bowl). It's really easy to put the little seal that goes over the spring on the accelerator pump on backwards (I have), that's the first...

    383 Stroker build

    Also are your heads 862? I tried to look them up but only found ls stuff. And how will you be using the truck? 11:1 is pretty high, especially if you're running iron heads. Most guys here building for the street stick to 9:1 or 9.5:1.

    383 Stroker build

    Hydraulic and solid are two different things. Hydraulic uses a small cushion of oil to control valve lash. Solid requires you setting the valve lash. Looked up your cam and it's a hydraulic. What gearing do you have? Since you're running an 8 inch lift I assume you've got pretty big tires. I...

    Bore vs. Stroke, a little math

    There are a ton of factors, my example was purely hypothetical pretending everything was equivalent except bore and stroke. Honestly what got me on this was wondering if large bore small stroke was actually as bad for torque as I've heard. I mean the 454, 460, and 440 were all over square and...
