But what they are is one of the best designed six cylinder inline engines ever built. A main bearing between each connecting rod, seven mains in total, and cam to crank gear to gear-no timing chain, they if treated right will last and last. Pfeil, I've known many, many people who have referred to 6 cylinder Chevy engines as "Stovebolts" over several decades. I once tried to research the history and/or background of the nickname, but only found a few guys who suggested that the engines were crude, and about as fast as a stove bolt. But that never satisfied me. It would seem by your reply above that you are more educated on the term. Please enlighten me. Link to comment Share on other sites More sharing options...

I'm not a Chevy guy, but I heard 60 years ago that on the early sixes the right side sheet metal vertical pans were attached to the block with slotted machine screws of the "stove bolt" variety, hence the name. I'm happy to have Chevy guys jump in and expand on this long-held nickname. 1 Link to comment Share on other sites More sharing options...
padgett Posted December 23, 2020 Share Posted December 23, 2020 Was even better when Pontiac put the cam on top. "Stovebolt" referred to the bolts used for the valve and timing covers in 1929. The name stuck. Link to comment Share on other sites More sharing options...
Bloo Posted December 23, 2020 Share Posted December 23, 2020 (edited) It is because Chevrolet's 1929 creation was literally held together with stove bolts, on the oil pan, side covers, etc. Common use years ago applied it to any of the old "low pressure oiling" Chevrolets, the last of which were the 1953 stickshift 235 and the 1953 truck & sedan delivery 216. As it turns out that isn't quite true. The 216, which landed in 1937, was a complete redesign even though it looks about the same. It has 4 main bearings instead of three for one thing, and a bunch of other major changes. It is a bit of a stretch to call it the same engine. In more recent years I have heard people referring to the 1953 (Powerglide) through 1963 full pressure oiling engines (235s and 261s) as Stovebolts also. Really stretching it IMHO, although it is closely related to the last "low pressure oiling" engines of the early 50s. The 230-250-292 is a completely new 7 main bearing engine, using some design elements of the small block V8, and is not related to the earlier engines in any way, other than having 6 cylinders. Today is the first time I ever heard anyone call it a Stovebolt. . Edited December 23, 2020 by Bloo (see edit history) 2 1 Link to comment Share on other sites More sharing options...
Frank DuVal Posted December 23, 2020 Share Posted December 23, 2020 (edited) I recently had to set some younger enthusiasts straight on this same subject. Stovebolt does NOT apply to the lightweight Chevrolet sixes form the early sixties. The Toyota Land Cruiser 3F engine of the 80s was more of a Stove Bolt than the 194/230/250/292 Chevrolet engines.😄 If only in how the valve cover was held on and location of the distributor. Proof? Look here: https://en.wikipedia.org/wiki/Toyota_Type_A_engine#Type_B And then work up to Toyota type F engine.

Mr P, I don't know enough about Pontiacs to offer a comment on those vehicles, but I do know that the Chevrolet valve covers were fastened to 2 studs by two 5/16" 'acorn nuts,' from 1929 through 1953, and did not require any screws as you insinuated to fasten the valve covers to the head. The bolts often referred to as 'stovebolts' are the 1/4-20 slotted truss head bolts on the side covers, oil pan and timing cover. These were the same type of bolts that were used to hold ovens together. The timing cover and oil pan are barely visible 1 Link to comment Share on other sites More sharing options...

We know that those particular engines were all designated as to who was getting them and how many they were receiving. I should have been more clear in my response and I will apologize for that. Thanks John. We are in south Florida for the holidays but the unlimited energy of the grandkids are amazing! No car down here but I’ve found a temporary storage place in DelRay Beach that can temporarily store my trailer as he loves cars. Now after that find no winter National show event down here.

padgett Posted December 23, 2020 Share Posted December 23, 2020 Gee and here I thought they were all "Blue Flame Sixes". Nothing is worse than an SME out of their specialty. BTW I never heard of a Pontiac timing belt failure. Of course I also never heard of the engine going over 50k miles either. and to be completely off topic once had a 68 Firebird that had maybe 2 options. OHC-6 with a three speeds Saginaw. Looked like it had been laid on its side and used for batting practice. Think traded a Saginaw 4-speed for it. Was my DD for about a year. Link to comment Share on other sites More sharing options...
Terry Bond Posted December 23, 2020 Share Posted December 23, 2020 Well, between this thread and the one about the Gullwing Mercedes, there is no doubt the OPs provided a ton of entertainment. However - the person who first posted questions about the Chevy hasn't visited the site here since the day following posting the original questions(s) (December 16th). The Mercedes dude peaked once but never responded. Both were asked for more details and photos. Scams? Kids having some fun? Inconsiderate? Nut-cases? Don't know, but the damage they inflict is - many are becoming hesitant to try and help someone. I know I've tired of people posting photos of parts, asking what is it? then never even bothering to say "thanks" and the piece turns up on evil-bay later with some stupid price on it. Some of these requests for help and info are beginning to remind me of unwanted robo-calls! Terry 5 1 Link to comment Share on other sites More sharing options...
Walt G Posted December 23, 2020 Share Posted December 23, 2020 Thank you Terry, yes it is indeed sad that people no longer say thank you but expect ( demand?) answers to their questions, the same ones who expect you to be courteous and hold a door open for them when entering or exiting a building with out even a glance of thanks much less the effort to say so. Lot of experts out there but none have hands on experience on many of the subjects they comment on.

Pfeil Posted December 23, 2020 Share Posted December 23, 2020 (edited) Before 1937 they are stove bolts. 2ND Generation 1937-1961 after 1950 (automatic's of 235 " are full pressure) they are Blue Flame sixes. 3RD Generation are again 194", (215" machined to that cu. in. for Pontiac on the 1964 and 1965 Tempest only), 230", 250", tall deck 292". These engines as said before all have seven main bearings. Also starting in 1962 a four cylinder 153" that shares all bore spacing, con rod, pistons, valve train sans camshaft....just two cylinders of the six lopped off. Was made for the Nova and industrial applications. Although the straight 250" was last used in 1979 in the U.S. it continued being used in countries like Brazil until 1992. As said before one of the best engines Chevrolet ever built. The OHC Pontiac (1966-1969) is a based on but different animal. water pump, oil pump, and distributor are shaft drive outside the engine, and a special crankcase ventilation/ fill station built on the side of the block. A COMPLETLY different block/head. Overhead cam used finger followers like Mercedes and Nissan L-series 4 & 6's. The fiberglass impregnated timing belt was the first and John DeLorean had the patent on it. 230" from 1966 & 1967, 1968 it became 250. The Sprint engines making 207 HP in 1966 and 1968-69 230HP as a 250". All sprints engines using a GM Quadrajet 4BBL with a redline of 7,000rpm. At the drag strips properly prepped 4 speed Tempest were running mid 14's at 92MPH in the quarter mile. The engine is mounted upright just like the 3rd gen Chevrolet Edited December 24, 2020 by Pfeil (see edit history) Link to comment Share on other sites More sharing options...

In that article they mentioned that the three speed stick was ok in city driving, but once the car was on the HWY it was pretty much out of breath. Can't imagine what it would be like in a full size Chevy. So I would say no, way too underpowered only 90HP.

A full sized car transmission from 1958 era (1957 to 1961). The Torque-Drive was marked 1st and Hi. You better start out in 1st if you wanted any acceleration.😉 But it would take off in Hi if you wanted to.

I did an experiment with a 64 Biscayne 230/Powerglide a friend had with a bad block and head from running way too long with a blown head gasket between 2 and 3. I pulled the push roods out of cylinders 2 and 3 and ran it as a four cylinder. Yes, really ssslllooowww on acceleration, but would do 70 on the interstate. I still use that block as an anvil, really handy.👍 1 Link to comment Share on other sites More sharing options...

Frank DuVal Posted December 26, 2020 Share Posted December 26, 2020 Torque-Drive was a manually shifted Powerglide, so it held up well! Say what you want about slip and slide Powerglides, but they ARE STILL USED IN DRAG RACING TO THIS DAY! You can make them hold up to lottttttttts of torque! Plus they have that nostalgic whine and slightly lurch in neutral.😉 3 1 Link to comment Share on other sites More sharing options...
