My machine shop does mine for $50-$75 dependingwhat else i need done, it was definitely worth it for me to not have to mess with it lol and it looks factory like it came that way, not that it ever gets seen once built lol
And you need to notch only one side of your connecting rods too they too close to the lobe of the camshaft and some do hit the lobe of the camshaft too
Some brands of connecting rods are cleared for the cam lobs. Eagle 6.0 rids I bought are made to clear the cam lobs. I used a 1989 4 bolt main 350 block for my 383 build. The crank is an Eagle 350-383 crank/ Kith Black flat top pistons. Aluminum heads with 68 cc combustion chambers - 202 intake / 160 exhaust values Should be a good engine for pulling my 30 foot jet boat to work and back home
@@brettjohnson8009 I am pulling the 30 foot jet boat from Oregon to Alaska and back just fine with the 383 in the 1988 1 ton Chevrolet which I have used up 2 454 engines. The 383 does just fine and I used 6 inch Eagle rods - Aluminum heads with 202 - 160 values. 68 cc combustion chambers give a compression of 9.8.1 to run well on pump gas. The Holly carb is a 675 cfm. Jeg's spread bore manifold. The cam is a flat tappet regular RV cam for low RRP power. The 3 3/4 inch stroke with 6 inch rods make this SB a great pulling engine for a work truck. The 350 and 383 can't come close for torque with the 383 right away you feel the differences from a 350 and get on a steep grade to climb the 383 scoots right up just fine. Fuel milage goes to the 383 when it doesn't work as hard, so you keep your foot out of the gas pedal so much. This is a work truck for towing when all of these 383 videos someone is using a 383 for racing .
@@Lure-Benson Thats what I was thinking, torque is where its at , had a guy here that built a 350 with a bigger cam an big valve heads ,was gonna pull his camper ,thing was a turd and you could watch the gas gauge go down ,tried to tell him , but he didn't want to spend the little extra cash to stroke it ,sounds like you have a pretty good combo
@@brettjohnson8009 Long ago I had a 400 SB in a 1972 Bazer so the 400 has the same 3 3/4 inch stroke as the 383 just larger diameter pistons in the 400. Seems the 383 shows no difference from the 400 SB in torque. I learned using the 6-inch rod give a longer dwell time causing more fuel to be burnt on the down stroke. Yep, no need for some Hugh cam just feed the 383 the fuel then the longer stroke with longer 6 inch connecting rods caused more torque. On long flat roads like traveling through Wyoming the 383 is at walking speed just taking it easy with a 3500 pounds of jet boat and trailer being towed. At 55 mpr if I jam down on the gas the 383 breaks 16 inch x 75 truck tires loose. My gears are 410 and a turbo 400 .
If only gm realized this when they created the 400 gen 1 smallblock. Motown and others figured it out years later.

The 880 blocks have clearance in them. I believe it is because GM also used it for the factory 383 builds.
I hope your using ARP main Studs
Yes sir

@@Lure-Benson Just curious, how well did your engine pull the boat ?

That work should have been done before you machined the block.
True but when your kid changes his direction after its been done. Can't undo it.
Why would you not let a machine shop do this and it be done right
Because he didn't want to do it he didn't have time. And he said I did a fine job.
