Hey guys. Ive got an excellent running 85? chevy inline 4 (TBI) that Id love to use in a project. Only problem is the TBI is UGLY and theres alot of wiring. Any thoughts on cleaning it up/hiding the TBI to give it a more correct look? Thanks!
You could put the wires inside some conduit/tubing so they look like piping I suppose. I didn't think the TBI unit was that cluttered, but I'm used to them on V8s.
The easiest is to put a carb on it. You can get a distributer from an earlier model either points of electronic or you can get a mag for them as well. Iron Duke was the generic name for a GM pushrod banger. They came in Chevies as well as Pontiacs.
It is a second generation of the Chevy II four cylinder, then Mercury Marine 4 cylinder. Basically an in line 6 minus two cylinders. They came in a lot of vehicles, but not the Vega. GM used to offer a Holley 2 bbl intake, although I think it was discontinued long ago. Good luck with your project!
What's it look like now? MoPar had electronic fuel injection on some of its '58s (recalled and converted to 2x4), maybe that could be a route to follow if you want period inspiration. -Dave
Pontiac used to carry alot of stuff for both the cast iron block and the Super Duty aluminum block. I'd check the GM Performance Parts site (or catalog) to see if they still have part #s. Definitely carb it!
I had an Iron Duke 4 banger in a S-10..it was a 85 I believe....????... I ran the shit out of it...only could get 80 - 85 out of it..I drove it 200 miles a day for a summer job...sold it for more then I bought it for...super strong little engine motor..
im no chevy guy but yeah i believe the motor you posted is a different version of the early little chevy motor often mistaken and refered to as the iron duke , found in 60s chevy 2s and novas , boats , mail jeeps , and some forklifts ! i had on in my roadster pickup out of a 64 chevy 2 , neat little engine clifford makes intakes and headers for them , even ran em in minnie sprints, as stated though i believe the newer 80s engines are a different family and nothing in common
Does your engine have a distributor? The Tech IV EFI engines I have seen had a crank triggered ignition. If you eliminate the EFI you will need to do something about the ignition. As was said, at one time there was a lot of upgrade pieces available from GM for these engines. I have no idea what's currently available. Knowing what was once available might find you something to look for. There was even a laydown conversion for sprint car use. The stock blocks are fine when used as intended. A stronger block with five cam bearings is needed for good durability and big power.
yep that is what I was thinking called an iron duke to try and rescue the car from its demise. That and the cosworth. They were actually an upgrade from the banger in the box Nova from what I have read. Al they still had a distributer in '88. At least the ones in the S-10s did.
I'm often wrong, but I'm pretty sure the early four-banger engines that were based on the straight six are not the Iron Duke. The Iron Duke was a 2.5L that came out in the late '70s in Monzas and stuff like that. Used in S-series, F-bodies, X cars, Fieros, etc. Not the same as the early '60s bangers.
it seems the cheapest way to get any performance out of modern 4 bangers is to throw a turbo on it. with mild boost id think the stock guts would hold up. i like the idea of the gpg of the 4 banger, unfortunately you really need a banger hooked up to a stick ( my personal opinion) and i cant drive a stick. im thinking maybe a slant six would be a fun engine to explore for mpg/performance.. and they seem to go for dirt cheap. chris.
Whatever it is, its an inline 4 thats in a mid 80's S10. The truck has a 5 speed and its bagged. I dont have a title... bought it as a parts truck (someones unfinished project). Id like to scavenge whatever I can off it for a 31 model A build. Its a strong runner and with a little work I think it could make a decent looking, highway friendly powertrain.
It's a 2.5 liter TechIV. Often confused with Chevrolet's 153 cu in from the 1960's. Look at Mercruiser stuff. Carb'd, cool valve cover. You can get them in the 160HP range with little work. Look here: http://www.jalopyjournal.com/forum/showthread.php?t=193315
You can make them look pretty good, and they are cheap! I have this rebuilt one taking up space in my shop, and I can't even give it away!
You're not wrong this time. The Iron Duke was designed by the Pontiac division. The 153 Chevy II engine and it's Mercruiser variants were based on the Chevy 6 architecture of the time. Not the same architecture as the Iron Duke. Bob
Mounted a carb and mechanical distributor on an OT Dodge 2.2, when the brain took a dump. Made a bracket for the head and mounted it to the cam; kinda looks like a flattie. Much easier than fixing the bag o snakes.
