    I just cant keep myself away from this thread, no matter how hard i try.

    Oil tem/pressure install

    Just a thought, but if you're so worried about oil temp, I guess you're racing or towing? just a thought, but maybe install an external oil cooler with an inline temp sender? Heck, you can do what I did with my trans cooler and install hi and low temp senders wired to a double throw toggle, so...

    What adjustable rockers to buy at a reasonable cost?

    I guess you're talking to me, but i was pretty up front saying i've never run the cheep rockers. I'm sure you've googled it and have read the hundred horror stories, and i get it if you're just looking for confirmation from guys you trust. But the evidence is SO overwhelming that they're junk...

    What adjustable rockers to buy at a reasonable cost?

    I've heard good things about the PRW's as well, but not sure I'd compare them to those $230 rockers posted before. The PRW's are $300 more, and much of that will be presumably in machining, bearing quality and q.c. For that price, you're in Harlan Sharp and Mancini rockers territory and no...

    What adjustable rockers to buy at a reasonable cost?

    I hear ya, and I know I'm still not answering your question, but I have been researching rockers myself and have come across probably 100 horror stories about cheap rockers from all makes. The thing I notice about them all is, unlike most other budget parts, Chinese stroker assemblies, procomp...

    Lol, sorry, had my cheap a$$ Chinese rockers mixed up, thanks for clarifying.

    What adjustable rockers to buy at a reasonable cost?

    I dont have any experience with them. But that said, the way i look at it, there are 32 bearing assemblies between the 16 rockers, works out to about $6 per bearing, and thats if the rockers, shafts and hold downs are free. I've done a lot of skateboarding and semi-competitive cycling in my...

    What adjustable rockers to buy at a reasonable cost?

    Food for thought, I bought a nice set of mopar ductile in a package deal, probably about $100 for the rockers. I'm about to send them out to Rocker Arms Unlimited (rockerarms.com) to have them bushed and their ratio adjusted to 1.6:1. They also will banana groove the shafts and check geometry...

    Stopping the knock: Lower compression and ported heads...

    Hey Greg, I've followed your posts on FBBO and now here. Like a previous post said, you have to be reaching 1000 posts trying to help lol. There seems to be a common thread amongst the most knowledgable engine gurus here, "if only I could get the motor in front of me". Well, I think we all...

    Insulation done! Shop heater questions. Electrical gurus.

    Yeah there have been a couple on the market for some time but are *really* expensive compared to other forms of heat, expecially with propane run into his shop. Unless the prices came way down, I haven't looked at that in a few years... still, it is a viable option for sure.

    Insulation done! Shop heater questions. Electrical gurus.

    Regarding using a heat pump, depends on where in the world you live. Heat pumps are one of the most efficient forms of heat because they 'move heat' like a pump rather than 'create heat' like a fire. They are an A/C that acts in reverse. An a/c uses the freon to steal the heat from your home...

    No worries. This is what I'm good at, but the car stuff is where I need the help lol.

    Insulation done! Shop heater questions. Electrical gurus.

    True that the lower voltage heater draws more amps. But remember, you dont't buy power in amps, you buy power in watts (kilowatt-hrs really, which is just the watts x the amount of time you draw it). Remember that WATTS = VOLTS x AMPS So a 1500W, 100v heater (using 100 for simplicity) draws...

    Insulation done! Shop heater questions. Electrical gurus.

    Not true. If we're talking about electric resistance heat, they all work the same and all are 100% efficient, meaning 100% of the heat goes into the space. 240v vs 120v doesn't make a difference at all, because WATTS is power and WATTS is V times A. The only thing making it more expensive than...

    Insulation done! Shop heater questions. Electrical gurus.

    Vented heaters have a heat exchanger. So they use a flame to heat up air, that air is run across the exchanger to warm it up. That combustion air has tons of water vapor and other combustion gases in it (carbon dioxide and carbon monoxide, etc) and is run up a chimney. Typically, 80% of the...

    413 Big Block

    Seemed like the OP was looking to maintain the 413's low compression, so it seems to me this would be the ONLY time a 413 might just be a good idea. Of course, as Jim pointed out fitment is your biggest hurdle here... and the fact the thing was stored outside under a tarp. If you could just...

    Cheap insulation. Is there such a thing?

    Hey, Rob, you guys have some smart people here on the A Body board, take their advice! Evaporative cooling system, heck, as a test, you could run a garden hose up to the roof and literally connect it to enough sprinkler to cover most of the roof. It'll work. Water recovery system - take a...

    Cheap insulation. Is there such a thing?

    Great point, I only picked the PPG because it's common paint name thrown around the B Body site (where i normally hang out). Armed with your insight, I bet Rob could lower his temps quite a bit.

    Cheap insulation. Is there such a thing?

    That sounds nuts, but really works. The key is to cool the roof, prevent the roof from transfering the heat to the room (roof insulation) and then removing what gets through (exhaust fan in the hot zone).

    Cheap insulation. Is there such a thing?

    Here's where i'd start. Energy star reflective coating http://www.ppg.com/corporate/ideascapes/metalcoatings/products/coolmetal/pages/default.aspx Here's some fiberglass insulation that is designed for metal buildings. If you do it a little at a time, do the roof 1st - best bang for the buck...

    Cheap insulation. Is there such a thing?

    In the Georgia heat, I think the cheapest and most effective temp control isn't insulation and a/c. I would spray the outer surface of the metal roof with highly reflective silver or white paint and install a high CFM exhaust fan either in the roof or as up high in one of the gables as...
