  • How much does the Chevy SB2 have in common with a pickup truck 350? Lets find out! The small block Chevy as it were found in a pickup truck made its way in modified form to NASCAR racing in the early 1970's. Today they are still the same 350 cubic inch displacement but the entire engine shares no factory parts whatsoever. How did we get here from "stock" cars? Keith Dorton has been building NASCAR engines since the 1960's and has every iteration of the evolution for us to see. From the bowtie heads to the Pontiac Brodix 867s to the legendary SB2 into the current Chevrolet Performance R07 engine used in NASCAR today!

    At the very start of the 358 cube, small block era, the 1975 Daytona 500, Bill Jenkins, DiGard, and Donnie Allison caught the perfect wave, and Donnie put the car on the pole . By then, we at Jenkins Competition were 3 and a half years into our small block Pro Stock program. In '74 somebody from DiGard contracted Jenkins to build a small block just to do that . Almost all of the NASCAR teams were concentrating on the last of their big blocks, and had done very little or nothing for the upcoming small block season . I did all the machining on the rods, and the even less finished pistons . Worked like a charm, ,,, !

    I am 64 years old. I worked on my first small block Chevy when I was probably 15. I have been a mechanic all my life ( mostly heavy truck and diesel stuff) my son and I race dirt cars and have always built our own engines, still running small block Chevy engines. It blows my mind how many of these engines have been built since it was introduced in the 1950’s. Great video as always.

    We drag raced with an SB2 headed Dart aluminum block back in 2006 in a Top Dragster. The engine was 452 CID. It made 950HP with 2, 1350 Dominators an a 1" camshaft. Back then you could buy up all the SB2 stuff dirt cheap as the NASCAR teams moved to the RO7.

      The only person I revere more is Ed Pink. Look at what he did with what he did, the Cammer 427. That was and is still amazing 3000 hp. Keith Dorton is 2nd on the list for me. Robert Yates is third. He began the journey of the C heads. The block they had a lot of factory help, I can’t imagine any 3 inch main 3.5 bore block living like that and not absorbing half the power the heads made. The Boss 9 broke 3 inch main cranks and and were only faster than the FE TP at 3 tracks but would break a crank if they ran long enough to be faster. I saw the dyno numbers and the Boss 9 made 613 hp and the FE. Tunnel Ports were all at 590-603, but on race day they were all at 605 hp, 150 lbs lighter to boot. Amazing is how he started out in the age of FEs and had a career of engineering to his FR9 and xxx to come. The Cleveland and FE had the strongest cranks of the time and he really wanted that crank baked into the C and Ds like the he original Cleveland had and the 2.74 main 2.31 rods and combustion of the two were so well balanced like the combustion of the TP FE and 2.74 main and 2.43 rods were. Few people went that deep, using combustion at the pistons to balance the crank and rod throws at their most vulnerable moment is “old school “ that computers are just now being verified. Thank you folks for doing this, reading your feed is the high point of my day! I love all brands of racing. I have built engines since high school and hanging out at Larry Phillips shop on Division Street. I just listened to him trash my long hair and he couldn’t run me off. 1975. Me, Mark Martin, and Rusty Wallace working on the same car. I would never trade it. They ragged me about my beat up Mustang until I took them for a ride, I had a 431 cu 427 FE Tunnel Port that I could strand the front wheels up in Ist and 2 nd. And at 150 it was smooth as butter. No more FE crap. I built it at home with used parts. My 1/4 times put me at. 600 with two 750s and torque you will about need a diaper for those Gs and stubbed it with a 65 Galaxie front. Here I was later watching them run with the big boys! Those were the days. I lost my license at 15 before I had one until I was 21. I was taking an LS6 Chevelle to school on a country road, C&I driving and a blank top speed while the Chevelle likely turned around when he saw the lights up ahead. He gave me my $300 and the 9 inch rear.lol.those heads are worth my house after I ported them. But half what they cost if I had left them stock for 550 hp. I wish still had them , every set of heads I seen to send for finish at a machine shop seem to get displaced. Next time I’ll wait to do the eyebrows over the intakes and laying back the short sides, lol. I will tell y’all that you do absolutely the best films of our greatest generation who took the machete through the brush to build the best technology for us to leap forward in science, Legends one and all and grabbing this knowledge and method of making a winning car before they are gone. They developed telemetry. You can’t know what to ask until you figure out what you need to know. Your race background is what you share and we all benefit from, Thank you!

    I am glad you did this video. Following NASCAR from about 68 - 69 this is great. I remember seeing picture of those big block just setting on a bench in the garage area being worked on or being installed in the car. I have never seen anything like this on these engine. I have been in machining for 45 years, with 22 of those owing my own CNC shop, but never doing engine stuff. I did make some 4340 rods for a nitro Harley Davidson drag bike. If I could have changed directions I would love to have the chance to work with Robert Yates. He was my hero in NASCAR next to Buddy Baker driving the Dodge Chargers with those 426 Hemi's.

    It took me a lot of your videos to finally realize it was Keith Dortan I met when he was building engines for the # 10 car and Derrick Cope. I think it was at a little shop by the AP. I was at Pennzoil and at that time Pennzoil owned Purolator…. I was in the Petersen Publishing suite at Daytona and probably only 1 of a few hundred people that was trilled when Earnhardt cut the tire in turn 3 on the final lap of the 500.

    Another awesome video! Really enjoyed it. I bet I know why Keith ( who looks 10 yrs younger than he really is by the way ) refused to divulge any information about "cheating".........it's because he's still in there working. If he had been long retired like many NASCAR crew chiefs, drivers, engine builders, fabbers, etc, then it would be less sensitive, therefore more appropriate to divulge such information. Hey, I could be wrong, but that's my guess. THANK YOU KEITH!!!

    I remember when sb2 came out. It was pretty revolutionary at that time. It was pretty limited to cup motors. 18 degree heads were still a big upgrade for the short track guys. I stopped caring about racing a few years later. Mid to late nineties was the height of racing in this country.

  • @chrisd078

    My neighbor has a couple SB2 engines. They run them in NHRA and are 5 time national champs with that engine program. They were offered 300k for their car and turned it down. He said their car has won him over a million in purse. I saw one spare SB2 sitting in his garage. They actually bought 4 SB2s from RCR for a total of 15K used. I believe they only have 2 still. I highly doubt anyone who owns any SB2s would part ways with a program like that. But I agree I want one too, best engine era by far! It's a 10k rev machine, sounds so awesome!

    First off I want to say that I love your videos, I’m old school, I grew up in the big block era, driving old big block Chevelles, the 396,402,427,454’s but I’d have to say the strongest small block four bolt main I ever built was from a 87 K10 Suburban lol but coming in at a close second would be the 350 from a 1970 Impala, that thing produced a lot of power but the wildest small block I’ve ever owned would be a 1968 Corvette 327 that I found from an ad in the local Car Trader paper here in North Carolina and that thing lived in two of my cars that I owned, first a 1966 Chevelle and then my 1955 BelAir backed up with a M20 Muncie 4speed transmission and a 3:73 gear, man that was a wild ride, I think it surprised a lot of people when I went pedal down, even me lol

    You can think of the SB2 & 2.2 as basically, big block heads designed to fit an SBC.
    I had a good friend working at DEI around 04-05, and we put together an SB2.2 engine for my dirt late model. Back then, you could get a set of DEI or Hendrick heads for around 3k. The block was a work of art! It had carburetor jets machined into the oil gallery to oil each lifter. Every surface was polished, and any extra metal was cut out for weight saving. We had about 10k in this engine. All used cup stuff

    Camshaft besring diameters will never get smaller. The can bearing diameter determines the height of the lobe which effects what base circle diameter will be which determines what the core diameter will be.
    Bigger bearing = bigger lobe
    Bigger lobe = better profile resolution and bigger base circle
    Bigger base circle = bigger core
    Bigger core = better stability
