Building a High RPM 400ci SBC to Replace Broken "Compression Obsession" - Engine Power S10, E6&7
Рет қаралды 579,025
Күн бұрынOur 360ci Small Block Chevy dyno mule is broken! So, we’re going to take the parts we can salvage, put them in a bigger 400ci Small Block and turn it 7000 RPM on the dyno! And we'll answer the question: how do cubic inches affect power??

Here's a thing about the 400 blocks. 1970-72 all had 4 bolt main caps, and could be identified on the outside with 3 freeze plugs on the side of the block, the only SBC so configured. 1973 through 1980 had 2 bolt main caps (big block style caps), and the standard SBC 2 freeze plugs on the sides. The 2 bolt 400 blocks are more desirable for a build than the earlier 4 bolt blocks, they're stronger with aftermarket splayed outer bolt 4 bolt caps.

I had one in my truck I built once. I bought a 82 I think Chevy pickup 4 by 4 and I put a box and cab on it that was a 70 pickup truck. It was a turquoise color. I looked cool when I got it done. Only took 2 days to change the cabs and boxes out. I put a 4 inch body lift out of square tubing and had 36 inch super swamper stl on it.

2 bolt 400s are supposedly stronger than the 4 bolt plus you can install splayed caps on a 2 bolt block and 400s are notorious for having out of round cyclinders, i rerung a 406 as a ladt ditch effort and even tho the bore looked nice from the dingle hone it had bad blow by so it went in the corner and replaced the engine in a tube chassis vega wagon with an old stock 283 just so we could go to the strip, we tossed 305HO heads on it with a nice big cam and a dz302 high rise intake to try n wake it up some, it would pull the wheels effortless and run low 6s in 1/8th with the 406 with camels vic jr and big cam but with the 283 let go transbrake it would chirp n go very smooth steady and slow lol and ran around 8.5 not fast but better than sitting home.

My 406 SBC with Canfield aluminum heads full roller setup with the stock 2 bolt mains block and factory cast crank 11.125:1 compression was a 600+ HP engine all day long and drove to the track, raced all weekend long and always drove it back home! It was amazingly powerful for its weight, and definitely durable with the thicker webbing of the 2 bolt block and siamese bores of the 400 it makes them pretty damn tough blocks. The larger mains of the crank is also a good benefit for strength, even being cast. The only thing that I changed to from the factory design was the 5.56 to the 5.7 rod length, and clearanced the block and rods for the big roller camshaft. This is the only issue one may have. With the larger dimensioned crankshafts of the 400 and going to the larger lobed camshaft, stock rods you may not have too many interference issues? I know aftermarket beefier rods at the big ends have a chance of contacting themselves in certain degrees. So it's vital to check this out more than once and making sure you have a minimum of .020 clearance between your rotating internal parts. The only issue I ever had while racing was pumping the oil pan dry around 3/4 the way down the ¼ mile. This was self inflicted though, using a high volume high pressure oil pump and a stock capacity pan was a bad combination. And this was with crank scrapers and all the oil return passages were cleaned up and enlarged before assembly. This though didn't make much difference. Adding a 8qt pan and Swapping back to a stock type oil pump it would still start to cavitate the pump around the end of the ¼ mile and I would watch the oil pressure dropping off around mid track, while going through the traps at almost 20lbs of pressure @ 76-7800 RPM'S. It never hurt the engine thankfully, but the problem was the oil flow for the original hydraulic lifters which wasn't really required for my application, so the engine was pumping all its oil up to the top end of the engine and it couldn't return fast enough by gravity to the pan. The answer to this dilemma was oil gallery restrictors and my nightmare was over! It was amazingly different afterwards and oil pressure was no longer any problem or cavitation wasn't a problem I mean. 😊 Otherwise they are fantastic engine's for street or strip or even a daily driver with weekend warrior thrills LMAO!
@gordocarbo 5 ай бұрын
Wonder if a windage tray may have helped you If the oil gets whipped up too much (aerated) it can wreak havoc on hyd lifters possibly cauing P to V interference . If I build to run over 6k often I always go solid to prevent it. To each their own

Yeah, that huge ac compressor, and pull a loaded dump truck and see how much it loses, and disconnect a couple of spark plugs and see how much it loses. All of which have nothing to do with maximum dyno hp tests.

I love your comment on the core plug... In the early 70's, in trade school, that was one of the catch questions on an exam. They drilled it in our heads over and over and over; There are no "Freeze/Frost" plugs on an engine, they are "Casting or Core" plugs which are necessary to remove the sand from the hollow part(s) of the casting. They were never intended or designed to prevent damage due to freezing of the coolant inside of the block. Thanks for asserting and clarifying this for the viewers.

Sillicon, not all 72s were 4 bolts, my hubby found a late 72 built in november, k date, that was a 511 number with 2 bolt mains ! Most 2 bolts numbers were 817 or 509,, thats last 3 digits of casting num. On bellhousing end of block. Most 511 blocks are 4 bolt but pull the pan to be sure, also, some 2 bolts have 3 freeze plugs, hubby has shown me !

I forgot to put in coolant before winter and did the same thing, 4 vertical cracks, 2 on each side. I just took the grinder to them, filled and covered them up with JB Weld and ran it trouble free for another 3 years before I upgraded my valve train and spun a couple bearings on the crank journal. I'll pay for shipping and give you the scrap price for that block. Lol

I feel your pain. I got called away half way through winterizing my antique 1966 StarCraft and when I got back to finish it I forgot to drain the block and manifold. I was rewarded with dripping out the drain plug in the spring to find the block pushed out between the two center cylinders and the special mercruiser aluminum manifold ruined. What’s sad is it was low hour original to the boat and ran great. I was able to replace it with a later production salvage engine.
@CivilizedWarrior 10 ай бұрын
Oof, that sucks man. Inboard engines can be a real pain to swap out too, depending on where they are in the boat. That’s why I always make a checklist on cardboard and I don’t cross anything off til I finish each job. You always end up forgetting something when you get interrupted and have to come back and try to remember where the hell you left off lol

@@CivilizedWarrior at the time I had a toddler and an infant. My son was helping me but got cold and wanted to go inside. When I got inside I got wrapped up in other things and that’s the nature of how distractions go. It’s a Mercruiser 1A power package so it wasn’t too hard to pull it I just had to pluck the stern drive then lift the engine out over the transom.

@@Jon_Flys_RC oh nice, that’s not bad. My grandfather has a 91 shamrock 26’ and his 5.7 mercruiser is in the middle of the boat covered with an engine box/tackle storage bolted over it, with like 1/2” clearance on either side. You have to unbolt the motor mounts and jack it up just to change the plugs. Anyway that thing was a pain, we had to rig up a cradle with some I beams to yank the thing out. I love fishing, but man do I hate working on boats. Lol
