It’s so good to see your dad working with you and vice versa. For those of us who didn’t have that, it sets the standard for what kids deserve.

[@HappyHarryHardon]

My dad hated that I wasn’t interested in sports that he liked. So he never supported me in my passion for cars which meant I was alone in a one car garage putting my first engine together. With two 60watt drop lights and the door down to keep the snow out, I built that motor for myself and a little for my dad to show him that I don’t need him. If my dad couldn’t derail my love of cars nobody could. That was a hard but valuable lesson for a 13 year old with a full time job.

[@wallebo]

I never did one thing with my dad growing up. He was in prison so that definitely affected my childhood. I was a grown man when we met. Needless to say, it wasn't the same.

I have personally seen a ball bearing being reassembled using Masterfoods brand tomato sauce to hold the balls in place. Needs must when the devil drives and all that. Thankfully it was a polymer bearing intended to run in seawater, so we didn't have to find out if tomato sauce is an effective lubricant.

I built my 383 back in 97 long before kit's and crates were available. Finding the right block casting was key to avoiding alot of headaches. Engines still in my 80 Firebird after all these years and runs great, so yes I would love to see you folks do an old school 383 build. Thank you for the great content guys.

[@luckyPiston]

Same same in 97 , the Vortec head was a new thing and u could buyem from GM assembled for 400 a pair , Edelbrock started making a carbed intake so thats the route i took with my 383 , the new powdered metal rods from GM as well , no need to clear the block but the cam was another matter with shaving down the shoulders on 4 rods. That motor pulled so hard that ever since i've thought doing a 350 is pointless. Now im playing with a 383 crank in a 305 and ported swirl-port heads for my S10 , can it make 400 lbs torque and knock down 20+MPG ? should be interesting !

[@genefogarty5395]

Huh, '97 was long before kits and crates were available? PAW was offering 377, 383, 385, 388, long blocks, short blocks and rotating assemblies back in the early '80's. Their catalog was about 2 inches thick and covered everything from Chevy 235 straight sixes to Desoto Hemis, to their Godzilla 514 inch Ford 460 stroker kits. There's no less than 9 different crate and kit suppliers in the random issue of Car Craft from the '80's that I just picked out of my pile, the original RHS, racing head service was a pioneer of the crate revolution ten years or more before '97. Super Shops was another mega catalog that offered the same stuff, they just came along later in the decade, I still have all those catalogs, I wish the prices were like that today, lol.

i always use silly putty to check crank clearance. put an 1//8" layer of silly putty over the problem area, rotate the crank past the problem spot nice and slow, and then peel the putty out and check the scraped part for thickness to see the clearance. sometimes shows you something the feeler guage and line of sight cant

When I get a fresh block for a stroker, I set up a pair and check clearance and then make a grind on all the bottoms, rough cut if you will then recheck all of them. Most times it is fine but occasionally I have to touch up 1 or 2. It goes much faster than doing 1 or 2 at a time. Great video and thanks for taking the time to do it.

[@dianedonovan4073]

great video, making stroker crank fit sbc block is quite a project. one tip for checking cam lobe to con rod clearence is to use nylon tie which is usually .045 thick when rotating assembled shortblock, inserting between moving parts is easier than trying to use feeler gauges i've found. good luck with your project!

[@torreypines3074]

We still run our 383's every day here in metro Denver and they are very fast. The secret for STREET APPLICATION is 11 to 1 compression with aluminum heads and 91 oct. pump gas. This is what doesn't work here with our thin air: Big cfm heads, big cams, big carbs. We know as we have tried all those combos. Our 383's actually outrun our 400 smallblocks. My S10 383 outruns our cammed LS 6.0 S10. Its all about the combination of parts and the application.

[@craigsowers8456]

Nice job ... just a word of caution. When you finish with the clearance cuts, do go back in with a whizzy wheel and dull the perpendicular edges ... there's no "knife edges" on machined metal ... ever (unless you want stress cracks to appear). Time consuming stuff but necessary. Look forward to more on this build.

Yes, when I did engines years ago, I used a T bar first, then a torque wrench. The T bar is more sensitive than a power tool, and pretty quick.

[@notsofresh8563]

It is just for mock up to check rod clearance, probably only 20ft/lb on those nuts. Way faster with a cordless, when it is apart and together 15 times while clearancing. They for sure use a torque wrench when actually assembling.

[@StainlessTIG2]

I’ve built so many of these SBC 383 and stroker fords combinations when I was working in a machine shop. On a 9.5 deck SBF 393, 408, and 418 about 30 minutes of clearance grinding and done. So much more work when assembling a stroker SBC. I used to convince people into buying a Bow Tie or Dart block because of the extra shop hours $$$

[@genefogarty5395]

I built two 383's with Scat rotating assemblies and their stuff is top notch IMO. The attention to detail in clearancing is a PITA but a necessary evil. We contoured everything with a cartridge that we used a carbide on to avoid any problems. Both engines are still going strong years later and one even gets some nitrous now and then, the other is at just under 100k miles of camper towing. Your customers are very lucky to have such skilled and caring builders/machinists. I'm nowhere near the caliber you guys are at, but with the assistance of a machinist that I have to drive 2.5 hrs. to go to, I can build some good junk, lol.

[@bearbait2221]

I did this 1 time and the ARP rod bolts will hit the cam if it is a thumper. More grinding!! cool vid thx

That is such a pita on a 400 crank I agree. Worth cutting up an old junk rod without piston so you can do both sides of each journal at the same time.

Hello - You guys are GOLD, I was doing things like this in 1961. Thank You

[@78Mitsu]

I love watching your videos! I usually do the bulk of clearancing on the mill then clean it up with the die grinder. Personally, I like to come back with a 120/220 cartridge roll and clean up all the stress risers and smooth out the casting around the bottom of the bore and the lifter valley and a light polish on the outside faces of the crank, get as much oil returning as possible for high rpm applications. Also, I like to use raised compression height piston so the zero deck leaves 5ish so if it gets rebuilt again switch to std piston still have 5 on the decks to clean up.

[@donjohnston4215]

Was doing a long rod (5.7”)400 sbc build years ago. Was using a hydraulic roller cam and the top side of the rods were hitting the camshaft in just a couple places. Had to grind a small amount from the area on the the rod where the cap bolts would thread into. The next time I had it apart I upgraded to better pistons and rods and these rods were already designed to clear all areas on the engine. I believe they were eagle series 2 rods. That with sealed power forged pistons and eagle cast steal crank. All balanced, GMPP fast burn heads, comp cam 236, 244 @.050 550 lift 10.7-1 comp. Thing was a little screamer and was bulletproof. Outstanding combination.

[@redmesa2975]

Over the hill from you in Rifle Colorado. In high school, ‘83 or ‘84, my buddies dad built a 383 for his truck. I remember all the fuss about using a 400 crank in a 350 block.

What I have done when setting a block up for clearance, i would take a stock rod and cut the long part of the rod flesh of the big in of the rod. I would bolt the big end of the cut rod onto the crank with a bearing in it. You can install the new rod a piston to the same rod journal and this will hold the rod in place to roll the engine over to check clearance.

The compression ratio needed is directly tied to the cam timing specs. David Vizard covers this thoroughly in his books and on his KZbin channel. Higher compression helps with better gas mileage too. The piston to cylinder head clearance also needs to be set.

It’s great that you guys are trying to keep the CR in the 9 to 1 side. But; you are talking here static compression ratio; there are in the net good formulas to calculate Dynamic Compression Ratio. If you guys try it, you will find that actually, you can run your engine on a higher CR ( static) and get more power whit low octane fuel and at the same time add more reliability to your customer’s engine… saludos!!

[@stoneyswolf]

My 383 I built had the same clearance issue. My 400 the machine shop suggested I use 5.7 rods probably not a bad idea but it was even worse than the 383. Had to clearance the block not a big deal but also had to take material off the edge of the rod bolts where they swung up towards the camshaft because they were contacting the lobes. I lost count how many times I assembled that engine before I had at least.080 clearance with the cam. I built that 25 years ago still going strong.

I've built several 383's, they do make connecting rods with tighter radius on the rods big end to clear the block and camshaft. For what it's worth and cost to upgrade a stock block, just purchase a new Dart SHP with the wider pan rails and raise cam

[@richb4099]

Check the rods to the cam on 1-2 and 5-6 If I recall right. The inner rod bolt shoulder area can hit the cam lobe on those cylinders every second revolution. I used to grind the side of stock rods right at the rod bolt head. Use a strip of cardboard to check it....I built a lot of 383's back in my machine shop life. Some rods are a lot worse than others. They do make "stroker" rods that help but the block grinding issue is common. The rods you have should clear the cam but check it ! Another issue I've had was blocks with bad core shift. Rods clear one side but not the other. Cam hole pad at the front is a tip off on that one. Cam and crank centerline is off to one side.......I built 383's back in the 1980's when that engine combo became popular thanks to John Lingenfelter and magazine articles......They make real good power and torque.. and Bandimere is going away after this season....that is a shame.....I've never been there but it looked like a great place other than the high altitude !

Once you get the first cylinders done square the block in a milling machine and use a 1" end mill spaced at 4.4" to do the other cylinders

That mousepad is awesome. Edit: as I was thinking that, your ad came up for them. I just ordered 2. Thanks guys!

Old school vs modern kit 383 is a great idea! Tedious I'm sure, but probably a great video series.

Love the good natured friendly banter between father and son.
