Im late to the game built my first anything with a SBC this year installed and repaired a bunch but never owned one until now 350 with 327 double hump heads been a great little motor so far
Bought plenty back then also lots of 097 solid cams as well-vette covers on my wife's 55 I bought in 64-65 at Rodman Chevrolet=Fresno. Her 55 was sold there new as well. We are the 2nd owners
The 350 was introduced in 1967 and prior to 1973, had plenty of power. Sent from my SM-J700T1 using The H.A.M.B. mobile app
My long stroke 301 is a 307 small bore block and a 327 crank, power pak heads, fenderwell tri-Y headers and a muncie M21. It's a party in every gear..my favorite is still a 327 .030 over 331.. but for max power you can't beat a big 4.125+ bore with a 350 crank 377! c Sent from my iPhone using The H.A.M.B. mobile app
That sounds about right. If a hot rodder wanted get up and go in the 50s he didn't use a small block chev. A y-block was way better. Chev did improve to a good functional easy to use engine. But never a cool hot rod engine. Sent from my SM-T805Y using The H.A.M.B. mobile app
I had a 327/365 HP in a 40 Chev coupe with a 4 speed and 456 (my daily driver) back in 1965. car ran exceptionally well ( solid lifter 30-30 motor) but today I would opt for a nice 327/350 horse motor > not real fast by todays standards but a great driver/street motor.
The 327 is a great little mill, i love them and have built and run them for years. I still have 2 cores i have been saving for years. My next small block will be a 350 though, as i will be towing with my 65 c10
Smokey and duntov built the first one (307) in 1955. That 30/30 cam was special designed for it. The 307 is my favorite one to build up but it's not on the list.
Ahhh. I didnt see that. Thanks. Other than that. The small block Chevy was NOT the engine of choice in hot rods in the 50s. The 307, 327 and 350 wasnt even made in the 50s. In later street rods yes but y blocks ,olds or nailheads were more common at the time. Sent from my SM-G930F using The H.A.M.B. mobile app
That's not a 301, it's a 307. 307 and 327 both had a 3.25 inch stroke. 301 is a 4 inch bore with a 3 inch stroke so 283 crank in a 327 block. 307 is a 3.875 bore with a 3.25 inch stroke.
Yes you are correct. A true 301 is A .125 overbore 283 with a 3 inch stroke. but as you mentioned a 327 Or 350 block with the short crank It does have a bit more torque than a 301 or 302. I'm going to build a 331 pretty soon. Sent from my iPhone using The H.A.M.B. mobile app
I thought quicksilver was using the classic "Baffle them with BS" and obfuscate the truth that its actually the lowly and shunned 307 resting in the frame rails. Although "long stroke 301" is one I haven't heard yet. The description of Large journal 283 stroker is more common for the 307. I'm sure plenty 283 blocks were fitted with 327 cranks long before Chevy did it for production in 1968.
Hello, My favorite would be the 283. That motor was our first one we built. Ported and polished heads, Hedman Headers, Joe Hunt magneto, 6 Strombergs on an Edlebrock manifold, a balanced crank, finned aluminum valve covers, and an Isky Cam/Lifter Kit. When we bought the motor, the Isky Cam and Kit came with the motor. We took it apart and had the other stuff done before we reassembled it for the drags. That motor had plenty of runs at full speed for the B/Gas class. Once we got the 6 Strombergs to run correctly, it was powerful and could run all day / night. We took it on an extended run around our cruising grounds…it performed well. No overheating or problems, except for the gas mileage. Those 6 Strombergs made such a sucking sound and did a number on our measly small Moon Tank inside the cab. Then the total rebuild of that original 283 to a larger 292 cu inch dimension with new Jahns aluminum pistons, a new Howard Cam and kit, and a Reath Automotive spec’d 671 blower for the SBC. An Isky Gilmer Belt Drive and another Edlebrock Manifold filled out the new build. Now, the Strombergs were still on top of the 671 and this motor sounded so powerful, that it scared our little neighbor on our first start up in our backyard. She went running back into our house calling for our mom’s security…awww. It was a powerful build and moved our 40 Willys into the finals of the C/Gas class in 1960…until… The next motors we had were the 327 in the 65 El Camino and the 2nd 40 Ford Sedan Delivery. They all ran like a top, but that was it. The 2nd El Camino’s 350 (not HAMB friendly) ran terribly with the crappy factory restrictions and that made it difficult to tune. When it was tuned, it got a whopping 9 mpg. That was the worst motor for us. Jnaki So, for us, it was the versatility of the 283, the size, abundance of different mounts, adapters, and speed parts that made it worthwhile. But, also, our friends had the same stock 283 (and not so stock 301) motors in their Chevy sedans (55-57) and that made it easier to work on when needed. Our vote: 283 SBC for sure…
I marked 350, today's best SBC for the $$$ involved IMO, have had them all including old BBC 348 and later 427, 454 BBC. If I was going to go old time/purist route(never been my program) would choose 327, (flatheads before my time, in my youth 16 in 1964) 69/70 had a 64 Impala SS 300 hp 327, 4 speed, 4:88 or 4:56, added scatter shield, changed cam/springs, headers, intake/carb, Street slicks, pretty good 1/8 mile Street racer, did not changed a thing in rear suspension, never wheel hopped once, usually would beat any stock (no mods or tire change/improvements) muscle car of that time frame in an 1/8 deal, tons of fun and good memories,. Would launch @ 5000 rpm and shift @ 64/5/600 rpm flat to the floor power shifts, broke every piece in drive line more than once, largest PIA was when I tore up center driveshaft support bearing/mount. That little 327 stood up to alot of abuse, stock 35000 K mile engine that I added the listed changes. Back in the 60's, Modifieds were big in Milwaukee WI. raced 5/6 nights a week, guys that I know and they ran real good ( champions, top 10 caliber) would buy Corvette 327 HP long block, changed cam/springs, added magneto, hilborn injection, Magic, a competitive race engine that ran all summer, more than enough HP for the cars and tires available then.
