    I'm having an easier time getting old SBC components. Everybody wants an LS in their rod. Practically giving away the old stuff. And I'm real happy to take it off their hands.

      Only problem is buying readily available parts if you're traveling.
      Most everything is special order. Could wait days or weeks for parts. One reason why drag and drive or power tour events everybody prefers the LS.

    As a self titled chevy parts hoarder....I say you did an excellent job of tracking down the heritage of this 350.
    If the block, heads, crank are usable, you have a good haul. I have done this casting/code dive many times, and I find it fun when you can still locate some old school gems.

    Additionally, up until the plug-size changes ('68-'69) all SBC'also had forged steel cranks which you can verify by the wider parting line and cast iron having a more pronounced, thinner parting line. (cast cranks make the best boat anchors...)

      SB Rods not cast. They were forged. Rods that were used for making pink rods could have been used for std rods too. Don’t make assumptions. Often pink rods color would be present on used rods. Sometime not. Another case of “don’t make assumptions.” In old days fakers would paint rods pink and sell as real.

    I had a set of those "186" heads on my 74' 350 I built for my 68' Nova, traded a 71' Nova for them from a machine shop, they did a valve job and PINNED the rocker studs because they like to pull out of the heads. They worked well in stock form. In this day and age, I think the casting date is what will bring the value for those heads, performance wise you would be way better off with late 90's Vortec heads,.

    • @DeanMk1
      @DeanMk1 2 ปีที่แล้ว +5

      ...but then you can't use the intakes that came with the engine, because the intake on a Vortec head bolts in differently, like a Ford.
      What makes the "good" factory heads, like the 461/462's and the 186's valuable is that they're a slightly thicker casting compared to some others.
      This means you can port them out more and you have more material to shave off the bottom of the head.

    • @chrisbraswell8864
      @chrisbraswell8864 ปีที่แล้ว +2

      High lift cams will pull the studs out because the gap on the spring at full lift are under .030" this causes them to actually = 0 under full throttle due to the vibration. Turn engine over until full lift is achieved and check gap with feeler gauge if under .030 get some new springs that are for higher lift. If lift is over .450 stock springs will not work and will eventually destroy the head by breakin off the the stud boss.

    Great video. Just a couple of tips from an old General Motors mechanic. First, I knew it wasn't a 327 without you ever reading the numbers. 1) 327's did not use a pcv valve, (nor did 265's,283's, 302's,or 307's)they had closed/sealed valve covers. They used an internal ventilator can mounted under the intake manifold that then fed to a tube on the back of the block. They didn't start with the pcv valves until they started making 350's.Also 327's never came with 4 bolt mains. Not even the 327/375 hp engine. So even though the 375 hp/327 was the highest horsepower rated SBC. It is usually less desirable than the lesser 370hp LT1 engine (Corvette only) only because the LT1 engine was a 4 bolt main block. I was lucky enough to own a 1970 Corvette 350/370hp LT1, And a 1957 Chevy with a 1965 327/375hp Corvette engine. And trust me, both would smoke the tires for a country mile. Also Chevrolet used the 2 letter suffix code until 1969, in 1970 they went to a 3 letter suffix code ie. CTX. Hope this helps. Thanks for the video

    Liked your video there is 1 thing if you rebuild that engine when it comes to the heads please take the time to replace those Pressed in studs because of the age of the heads and also being around small block chevy they seam to have the habit of pulling out or breaking off. I saw guy he took the rockers off and stacked a bunch of flat washers and use the nut from the rockers to help pull the studs out. After that I'm not totally sure sure if you have to drill the holes out bigger or if you can just use a tap. If you do this just take your time. Or just pull the studs out and maybe the machine shop might discount the job just because you pulled them. You might just ask the machine shop before you do it. But you would think it would save a little money 💰 I hope my suggestions will be of good use and I wish you best of luck

      Ray, I bought a 350cu out of an 1969' Nova SS in 1969 that had on the Air Filter a sticker that read 350 - 300 HP. So that's what I thought I was buying. Came with a 4 bbl Rochester carb. Gave $350.00 for it. Put it in a 1963' Impala SS, 4-speed. Engine only had 2,400 miles on it when I bought it. But once I got it running it became very apparent very early on that something wasn't right. There wasn't a 396' Chevelle in my area that I couldn't outrun! So about a year later I'd decided to beef the engine up just a tad-bit more than it was, and that's when I found out that what I had was a 350 cu - 350hp engine! As soon as I saw the 4-Bolt Mains I knew that it wasn't just some regular 350cu - 300hp engine. And after running the codes on my block, heads, etc., it was then that I knew I had a 350cu-350hp engine that came out of that 1969' Nova SS. Date stamps all indicated that this was an 1968', early production 350 engine, first year that the 350 came out and was installed into the 1969' year model Chevy's. And the 1969' Nova was a very early release as well, so it all fit perfectly. That was one of the absolute BEST running 350 engines I ever had! By the time I got through building it, there was nothing in my area that could touch it. The ONLY vehicle that ever out ran me was a 1970 Highway Patrol car while on the Highway (Interstate 40 in NC), but this was before I beefed-up the engine. From 70 mph running side-by-side we hit it. He squalled his tires when it kicked into passing gear, and that was the end of that, lol. I had a 4-speed Muncie with a 373 rear-end gear. So I couldn't have down shifted into 3rd gear, because I would've probably blown the engine up. So I just stomped it to the floor. Not the best speed for me to start a race off at. And I didn't ever make that mistake again, lol. But those old Highway Patrol cars were fast as all get-out back then! And there weren't very many (if any) vehicles that could out run one of them on the highway. I later clocked my old 63' Impala SS at 145 mph, after adding some goodies to it. I never did find out just how fast it 'would' go, but I know it had more to give. As I was chicken to run it any faster than what I did that one time just to see how fast it would go. Sorry for the Book. :-)

    I found your video by accident, but you might know something I am obsessed with. It might give you ideas for your next video. I have -291 SBC cylinder heads with (currently) 2.02 intake valves. These heads came in 2 Types with different valve sizes. Lots of machine shops would buy junkyard Type I heads, change the valves, and sell them as Type II in the aftermarket. Later, stock racers preferred the Type I's because there was more "meat" between the valves to work with. I thought you could use the marks on the bottom of the heads to know whether you had an original Type I or Type II. I can send photos if you want to pursue this idea.

    The partial VIN on the pad will tell you what model that block came from, Impala, Chevelle, Nova, Camaro, from the group of number assigned to each. As long as all of the stamped number and casting numbers are legible, it can be done. I believe all SS cars came with 300hp 350's, at a minimum, and yours is likely from a Nova, although that engine was also in a fair number of Impalas. Someone with a 1969 Nova SS should be mighty proud to have that, as long as the numbers line up.

    All ten Chivy small block denomiations have their own distinct sounds due to port configuration and the firing order being 1-8-4-3-6-5-7-2. Because garbage, boat-anchor, belly-button LS's have both a different firing order and port configuration, they do not even sound remotely similar to an SBC. This is my biggest reason for my disinterest in them. Hotter? Faster? Better? Dont care. I cut my teeth tuning a 1955 265 by ear as a youngster at my Dads behest. They didnt even have an oil filter, that 1st year of production. (maybe why they are so unobtanium!!). So once I realized that 28° of dwell yielded the hottest purple-white spark to be had out of a Delco coil it was all down hill from there. With care you can fit any SBC crankshaft in to any SBC block. We began experimenting with that in about '55.

    my guess to test my sbc knowledge, you can confirm since by now surely you have stripped block down n checked for cracks in weak casting areas typically on these blocks. so here you go 1970 model large journal crank, pre 69 cranks had small journal cranks w/two bolt mains only used in 327 & 283 motors,350 had longer stroke with 3 acc. mounting holes in head for AC bracket on drivers side, pre69 only had one acc mounting hole in head as AC was mounted on pass. side. heads are 67cc chambers n they were prone to losing rocker studs at high rpm and dbl springs w/1.98 I valves giving 9:1 compression w/ flattop pistons, now 2.02's were only used in HP engines with alum.factory intake, manual trans and four bolt main caps. HEI didn't come out until 1974 .guessing your motor outta '70 camaro , '70 chevelle 2dr or 4dr, '70 el camino, '70 nova, or '70 impala 2dr or 4dr. since its not four bolt main, not SS model factory 200-265hp....so how close am I? have you continued search? mine is '69 327 dbl hump heads small journal crank, came outta my '69 4dr. impala 350tran, now its in my '70 SS el camino BW T-50
