Re: 4 cylinder '67 C-10
Chevette's had two engines. In the Scooter, the engine was a meager 1.4 Liter. The "upscale" Chevette's got the zoomy 1.6 Liter engine.
I bought a '76 Scooter in '82, that had a 1.6 out of a '78 (wooooooo). But, when I had the exhaust system modified with 2-inch stuff right off of the down pipe below the manifold, then fitted a baby turbo to it.....I had a lot of fun.....til I sold it to my youngest brother who still owes me money on it after he totaled it. But, there's good news: He will never owe me any more money than he owes right now. Nor will his older brother. Yeah, I'm hardcore the 2nd time you want money.

Re: 4 cylinder '67 C-10

Re: 4 cylinder '67 C-10
The 153 Chevy II engine was never called the Iron Duke. The Iron Duke was the 2.5L 151 cu in Pontiac built engine. I have an old magazine from 1977 introducing the Iron Duke . My 1982 Camaro owners manual refers to the 4 cyl engine in the Camaro as the 2.5L "Iron Duke". I do agree that the 153 is a better engine. My granddather had a old inboard boat built in 60's with a 153, and ran it all the way up until about 5 years ago with engine problems in all those years. I think some people have sorta retronamed both of the engines the 151 and 153 Iron Duke, but its not correct to my knowledge. I can't find any factory literature referring to the 153 as an Iron Duke engine.

Re: 4 cylinder '67 C-10
I believe it was called the "Iron Duke", so people would not think it was the aluminum engine that was first installed in the Vega, the "aluminum puke". My brother had a '72 Vega GT. It puked it's oil out, when one of the cylinders dropped. These motors were infamous for puking oil, due to the aluminum or alloy cylinder sleeves. Once the block was resleeved with steel, the engine did much better. By the time GM got around to fixing the engine problem, the public was put off by the Vega name. Not even installing the Cosworth engine saved the Vega.

Re: 4 cylinder '67 C-10
When I was still wrenching - 20 years ago this August - EVERY old timer in the neighborhood had a GM with a 2.5 liter iron duke. Cutlass Calias', Celebrities, Pontiac Somethings. They were in everything. There are two notable things I remember about that engine.
1. You couldn't kill it. 2. EVERY one that had air conditioning - and they all did - would crack the hard aluminum hose off the back of the compressor. The shop I worked at had 5 stalls. Back then when doing AC work R12 was $1/pound and Al Gore hadn't yet scared the world about this man-made global warming crap. To do AC work like replacing a cracked/leaking hose you simply cracked open the system and let the R12 vent in the air slowly so no oil would come out with it. One day there were only two of us working for some reason. I had 4 stalls tied up with 2.5 liter GM products in various stages of getting the AC hose replaced. Another time we couldn't get a hose delivered so I hopped in my car and drove down to Midway Chevrolet on University Ave. in St. Paul. They knew I was coming and what for. The replacement hose came in a box as thick as a pizza box and about 14 inches square. When I got there the guy pointed me to a stack of pizza boxes as tall as me and instructed me to grab one and sign here. That 2.5 liter was a great little engine but it sure shook those hard AC lines. Oh and pretending this is still on topic - I've never seen nor heard of a 4 cylinder in 67-72 GM pickups.

Re: 4 cylinder '67 C-10
Lots of the GM 4 cyls out there-just look for a 18' or so boat with the 120 or 140 Mercruiser and there they'll be. Lots of engine and parts on ebay under boat parts. They are great marine engines, just be careful of used marine engines being frozen & busted. Be sure to check the oil, most are milky.
On 2 stroke diesels, here is a pic of mine in out MCI bus conversion- right at 400 hp backed by Allison 5 speed auto. Many buses are still running the DD 2 strokers. They sound great! |

Re: 4 cylinder '67 C-10
They just introduced a "new" version of the iron duke as they use them to power the World of Outlaws cars (Toney Stewart's team was the first to use the redesigned iron dukes, funny how "tiny" 4 banger can pull the front end going down the straights and get them up to over 100mph in a few seconds!?
As for the OP, the 4 banger in the Nova was pretty rare, and if they did come in the truck I'd say it was "VERY RARE" as in a COPO only and probably only a handful ever made. Could you put one in, yeah, they bolt right in, but WHY?! |

Re: 4 cylinder '67 C-10
I have never seen one with 153 4 cylinder engine, but with the right axle ratio, I am sure it would be a great around town engine in a truck!
As far as the other 4 bangers go, the 'Shoveit' engine was a 1.6 and the Vega/Early Monza/Astre aluminum engine was a 2.3 litre engine. Sad thing with the Vega motor is if you sleeved them, they ran forever and a day, which was a lot longer than the body did on them here in the Midwest!!! The 2.5 came in several flavors, but from what I can remember, there was the RWD version with the Chevrolet bellhousing pattern and the FWD version with the small metric bellhousing. As much as I hated those rattly,noisy, underpowered engines, they usually ran forever. They usually did not make enough power to blow themselves up!!! Mike

The 6-71 and 8V71 were mainstays of the trucking industry until the mid to late 80s, sales dropped radically and Penske bought Detroit Diesel from GM. They came up with the Series 60 which is four cycle. There are very few two cycle DDs in onroad use any more, mostly buses and fire equipment-a few buses still had 6V92s as late as 2007 or so. Military and rail still buys some new two cycles as do NYC tall buildings (fire pumps) and airport ground service. Not very many. DD is owned by Daimler Benz now and they are transitioning to MBZ based new engines, but they plan to support the two cycle base until roughly 2050. The earliest supported engines will then be 114 years old. We had a 4-53 IH Travelall (a commercially done conversion bought surplus) for a long time. It slobbered oil and howled but it never broke down. We sold the truck due to extreme rust in the late eighties and the guy who bought it wanted the engine for a road grader. I still have the steering wheel, the rest went to the shredder in St. Louis. A 4-53 fits in a pickup but not by much. It also weighs a thousand pounds so be advised a front end beef-up is in order. And your neighbors will love you when you fire it up early or late..... |

Re: 4 cylinder '67 C-10
GM fours made the same mistake Ford did with their V8s-they made way too many different ones. The Iron Duke was a decent engine but heavy. The Vega needed iron liners, which it only got aftermarket. They still haven't made the obvious and correct one-half a small block. Or an LS now. With the SBC bolt pattern.
The Chevy II engine is actually in big demand for vintage circle track racers. They can't find 'em. Pontiac and International made fours that were half an existing V8 and took the same head, Chevy never did. Why not I don't know. They also don't make a gas and diesel with the same basic block. If I were GM I'd finally put the big block to rest and make a gas version of the Duramax, sharing the block and crank forging at least plus the ancilliaries. Detroit Diesel did a great thing with their engines. They were made so they could be left or right hand rotation, the inlines could have the blower and/or the exhaust on the left or the right, starter on the left or the right. Chevy (SBC, BBC, Corvair) made it so you could have reverse rotation without butchery, but there are no inlines so it's academic whether the heads could flip. This was very important in marine engines. |

Re: 4 cylinder '67 C-10
The first road tractor I owned had a Detroit in it. Nothing like having it run backwards.

Re: 4 cylinder '67 C-10
That old 153, was basically an inline 6 with 2 cyls lopped off, & yes different than the Poncho 151. The 153's also were in some of the old mail jeeps. CrazyAL
