We've teamed up with Epic Desk on a limited edition custom mousepad/work mat inspired by JAMSI Online! epicdesk.shop/products/jamsi Be sure to check it out, and pre-order while you can! Pre-orders will last through August 13th, 2023 and once that closes, they'll never be available again!

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.

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.

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!

[@quirinonavarro1857]

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!!

[@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.

[@silentbobfan32]

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

[@wilmamcdermott3065]

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.

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.

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.

If this is going to be a burnout motor i definitely wouldn't have gone with an expensive aftermarket Dart block, you wouldn't need really high horsepower, more high RPM than than anything really...a good crankshaft, rods, pistons, hardware, balancing, high flowing heads, good quality cam, lifter, pushrods, valves, springs, roller rockers, retainers and timing chain is where my money would be spent. I would be willing to sacrifice some lift to spin it faster without valve float, it's going to be abused, so i would get good quality parts but not top of the price list stuff and save all that extra money to build two, you will absolutely get much more from two engines than one with slightly higher quality much more expensive parts 😂

[@joelpierce3940]

Interesting. I did a 383 using a Gen2 Lt1, and there wasn’t much clearance needed at all. I would like to see you do a Gen2, but with HEI distributor. Reverse flow heads should make more power.

I bet you're relieved you're not clearancing for alloy rods 😎 This sort of tedious task is why 'built' engines cost so much more than the sum of their parts - remember that, folks. The "big" shops, that do a lot of stroker work, will just drop the block into a CNC mill and use pre-programed cutting, but this is an excellent example of what the 'average Joe' can do in his garage.

You need .060" between the cam lobes and rod... Incase a rod bearing goes out without hitting the cam lobe. That's how thick the rod bearing is, .060". Small base circle on the cam helps with a 383" engine.

More grinding to use OEM rods in a 383. You could go the other way and use a 4 1/16 block with a 350 crank. Probably semi custom pistons though

Sure would enjoy your outstanding channel more, if the soundtrack could exclude the annoying high-pitched mechanical noise as earphones make the experience painful. I look forward to many more informative segments. Thanks for sharing!
