    75 Firebird

    My fiance got me a 75 Firebird Espirit for my birthday. Gen 2 Firebirds have been my dream car for a long time. Now I have one! It's just a roller atm, no engine, trans, or interior. The body is straight and the only rust is the drivers side floor pan. It was an Espirit with a 350/th350. Long...

It is a 1978 k10 Chevy Bonanza that has a 2007 5.3 LM7 swapped into it. If you guys see it anywhere or on craigslist, or have any information please let me know and...

    School me on 3 speed manuals

    So I'm eyeing a c10 with a 250 and a column shifted three speed manual. I think it could be an excellent little daily driver. I can't find anything about them. How did these transmissions hold up? Can one have fun with the column shifted manual? Also I seem to recall the i6 3 speed trucks also...

    Good Highway Tires

    So I'm going to be buying tires at some point for my truck. I have never had a new set of tires so I figured I'd try and get opinions from you guys. I tried searching threads but it all seemed to be all terrain oriented or offroad stuff. I want to run 235 85 r16s, seems to be somewhat fewer...

    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...

    Bore vs. Stroke, a little math

    So this morning I got to thinking about bore vs. stroke. I'd always heard that the longer stroke gives more torque due to the leverage, made sense to me so I never thought past that. But this morning I was thinking about how at the same displacement and compression engines with different...

    Stepside bolt kits and strips

    So I'm going to need all fresh hardware for my bed. Does anyone have any experience with the brands out there? Anything to seek or avoid? I want stainless steel bolts and strips for my truck. And this is for a longbed. Thanks all

    454 bolt ons

    So I found this video on youtube. They pull a 454 from a motor home. They dyno it as it came out at 330 hp and 475 ftlb. They slap a top end kit on it and make 560 hp and 535 ftlb on 87 octane. Thought you guys might find it interesting.

    Tach signal wire

    So I have an 81 c2500 with a 454/th400. It didn't have a factory tach but there still was a plug on the tach signal. When I got my tach cluster I just kinda unhooked it figuring it wasn't doing anything and made my own signal wire. Recently I traced the factory signal wire and found it connected...

    Anyone use a DCC fan controller?

    So I've been searching around for fan controllers recently and stumbled upon this site. http://www.dccontrol.com/constant_temperature_controllers.htm From what I've read about them it's really high quality but abit hit and miss when it comes to customer service and how long it takes to get it...

    4wd 4l80e to 2wd

    So I have a buddy who'd give me a 4wd 4l80e. It hasn't run for a long time but it was alright when left. How much effort/expense would it take to convert it to a 2wd tail housing? Around here 2wd 4l80es command a 300-400 $ premium over 4wd. This is all a ways off but I got to thinking swapping...

    Cooling fan horsepower

    So in an episode of engine masters they tested some common mechanical cooling fans to see how much horsepower they actually use. They had a mild 350 that made 349 hp and 406.9 ftlb. They were winding it out to around 5500 rpm. They had a radiator and shroud, all the fans were the same diameter...

    stepside vs fleetside bumper brackets

    This summer I'll be swapping to a stepside bed. Currently the truck has a sport bumper, looking at the lmc catalog it looks like fleetside has inner and outer brackets and the stepside only has an inner set. How similar are they? Do I need to get stepside brackets or are the inner brackets from...

    Fuse box picture?

    So most of lettering and numbers have worn off my fuse box. I want to make sure everything has the proper fuse and was hoping that someone might have a picture of a fuse box with the proper fuses. I have an 81 c2500 with electric windows and locks. Also my left turn signal indicator stays on...

    14 bolt clunks on throttle release

    So my dad and I swapped my gear ratio a couple weeks ago from 3.73 to 3.21 in my 14 bolt ff. Changed out the bearings and installed the new ring and pinion, did the break in procedure then I had about a 200 mile drive back to college. I didn't notice anything on the freeway, but I was driving it...

    14 bolt ff spider gears slop

    So my spider gears have some slop, the shafts sit firm in the carrier and the gears are fine on the shafts, but I can hold one gear and the opposite has a fair bit of travel. I think this is also the source of my clunking when going forward to reverse (or vise versa). Now one of the large gears...

    Gear and tire height spreadsheet calc.

    So I made a spreadsheet that calculates displacement, compression, and piston speed and posted it under engines and performance. I then decided to make one for gearing, tire height, trans ratio, and speed and this is it. Just choose what you want to solve for, enter in your data and it'll give...

    Engine Calculator Spreadsheet

    So I decided to try and make a spreadsheet that calculates some general engine values and I came up with this. It calculates displacement, piston speed, and compression ratios. Works with any engine configuration. I believe it to be accurate but if you find an error please let me know. If you...

    How much effort to pull the cab?

    So this summer I'm hoping to do a bed swap on my truck (lwb fleetside to lwb stepside) and was kinda thinking while the bed is off might as well paint the frame to protect it while it's still good. Seems rather silly to paint half the frame so I got to thinking about pulling the cab too. So how...
