92Regal Posted May 27, 2003 Report Posted May 27, 2003 Hey guys, newbie here. I currently own a 92 Regal with a series 1 3800 and I was wondering if the intake manifold was aluminum or cast iron. Despite searching the web, I've been unable to dig up any info. Also, in the past I owned an 88 Cutlass Supreme with a 2nd gen 2.8L. I was wondering if you guys can tell me if the intake on the 2.8 was aluminum or cast iron. Thank in advance! Quote
Panopticon Posted May 27, 2003 Report Posted May 27, 2003 yah! another regal. Im a regal noob too. aint it great Quote
Slade901 Posted May 27, 2003 Report Posted May 27, 2003 Someone should be able to answer your question. I was thinking that you might be able to verify it with a magnet. The magnet should attract better with the cast iron than aluminum. Quote
GnatGoSplat Posted May 27, 2003 Report Posted May 27, 2003 The 2.8L had an aluminum intake manifold. If I had to take a guess on the 3800 intake, my vote would go to aluminum, but I honestly have no clue. I know the plenum is aluminum, so I would think the intake is too. The magnet idea sounds like a good one! Quote

The magnet should attract better with the cast iron than aluminum. Well, I'm taking a Machine Tool course at a community college and if i remember right, cast iron is hardly magnetic. Maybe a little more than aluminum (aluminum has no magnetic properties at all). Quote

SmokesGTP Posted May 27, 2003 Report Posted May 27, 2003 Yeah its aluminum upper and lower. Cast Iron block and heads. Quote

SmokesGTP Posted May 27, 2003 Report Posted May 27, 2003 Yeah iron is definetly magnetic. Those little filings kids use to play with their magnets is iron filings. You ever seen those in those science kits for kids, my lil' bro has one. Quote
Slade901 Posted May 27, 2003 Report Posted May 27, 2003 I am sure ordinary cast iron is magnetic but you might be talking about high strength cast iron/alloyed cast iron such as "austenitic cast irons" which are non-magnetic. http://www.key-to-steel.com/Articles/Art21.htm Quote
91GranSport Posted May 30, 2003 Report Posted May 30, 2003 Early models like yours and mine had cast iron intake manifolds, but later models had a thermoplastic intake manifold.

91GranSport Posted May 30, 2003 Report Posted May 30, 2003 Sorry, you meant the intake manifold, right? Damn, I was thinking of the intake runners. Sorry dude. Quote
JS91Z34 Posted May 31, 2003 Report Posted May 31, 2003 Cast styrofoam I'm sure they'll find a way to use that. It won't surprise me Quote
GPRACER Posted May 31, 2003 Report Posted May 31, 2003 Cast styrofoam I'm sure they'll find a way to use that. It won't surprise me The vortec 4200 and the 3.5l dohc use styrofoam to mold the engine blocks, The metal is poured around the the styrofoam, the foam melts leaving the formed block. Not quite sure how, but I remember doing a couple of courses on these engines when they first were introduced, and I remember something about foam. Quote
Brian P Posted May 31, 2003 Report Posted May 31, 2003 I thought most all manifolds are created that way, look at the 3100 upper intake. Surely whatever is there to make the casting must be destroyed, the manifold is 1 piece and something has to be destroyed in order to get it out of the inside!! Quote
ismellrealbad Posted May 31, 2003 Report Posted May 31, 2003 this reminds me of a big debate 2 of my friends had. if lead is either very soft or very hard. one of my freinds said he was almost positive it was extremley hard cuz its in lead vests and huge led medicine balls...and of course the old style gun bullets (i forget what he said im geussing the kind of gun from like 1700). the other one was like well if its so hard then how come its in pencils and (something else) and i can swear on my life my science teacher said this....and no this was not a nerd debate it just happened to come up in a another subject and they both couldnt agree and i wasnt sure either.

GnatGoSplat Posted May 31, 2003 Report Posted May 31, 2003 Lead is very soft. You can even pick at it with your fingernail. It's also very dense. That's why it's used was used in vests, because it can absorb energy due to it being soft. What the hell are teachers teaching kids in school these days? Sheesh! Quote
Guest RedCutlassSL Posted May 31, 2003 Report Posted May 31, 2003 teachers don't teach shit. i'm finding that they usually don't even know what they are talking about. public educations is just terrible. I'm sending my son to private schools Quote
GPRACER Posted June 1, 2003 Report Posted June 1, 2003 isn't the "lead" in pencils actually graphite? Quote
Redfox340 Posted June 1, 2003 Report Posted June 1, 2003 isn't the "lead" in pencils actually graphite? Indeed it is... had to change it since many kids would get sick by chewing on pencils... Mmmm... pencils... aahgahaghahagahaahhgahga... - RedFox340 Quote
