Golden Ticket or Fools Gold? Decoding Small Block Chevy Casting Numbers for Budget Power

I just went through this numbers game with a sbc and we thought we had a 302 z 28 engine to find out that blocks been around in the trucks for years like you said , good video thanks for sharing bare 👍

Good job Kim. Good information here. Nice you're sharing your knowledge with people. Remember this, even the non performance can be turned into the performance versions with some machine work. Take care, Ed.

The stamped numbers on the pad in front of the pass side head will tell you what the engine is and what it came from. There are also date codes cast into the heads, block, and intake that can help narrow things down.

Its one of the first things i check...block casting and head casting!

Awesome! I always look at the date code vin number and suffix code to see what vehicle they came out of too!👍

That tab under the passenger side head. The suffix code is the best for finding out what's what.

The 010 I was told that was amount of tin in casting, nickel was weeded out in late 60s for machining purpose, great motors with good cam boss centering tho

The bread and butter 010 block...score! Yes, the metal in '69/'70, when they changed foundries and went to a higher nickel content was better. We have a '69 010 and a '71 010. In the timing chain valley is a 010 stamp (not related to the 3970010 Chevrolet part #). The 010 is the foundry stamp. The 010 is that newer foundry. We know our '71 010 is a 4 bolt because it came out of a Longhorn Truck and the trucks were 4 bolt. The '69 was from an SS350 Camaro and thinking it was probably a 4 bolt too. We have yet to drop the pans on both. Good engine you got there and a great building foundation! Cousin Mike is a great guy!

SBC forever! Mine is a two bolt main block, and I hammer on it hard and she just takes it. I have no idea what my horsepower is but it’s not a lot.

The pad on the rh front head area will tell what vehicle it came from.My experience is passenger car will be 2 bolt main C or K trucks 4 bolt main.Liked the vid.186s are 1969 1970 issued.

0010, yay I have a short video on crankshaft identification for SBC. The flex plate/clutch end of the crank has a pattern.

Watching now, love these type of videos 🏁

Awesome video brother. Thanks for sharing. Keep the content coming. Hope you have an incredible day. Much love and RESPECT brother . Stay warm

Mine is a 2 bolt 010 block. I built it back in 83. Stuck it in a 3200 lb car and beat on it spring, summer and fall for 21 years with no issues. Took it out and rebuilt it again. This time with ARP studs instead of main bolts and put it in a 2500 lb car. Been beating on it now for 5 years and it's fine. Sure, I'd rather have a 4 bolt but I work with what I have. 👍

Awesome very cool. 👍

I've always heard too that 2 bolt will handle a ton of power and the only thing a motor with more than 2 mains really helps with is durabilty if you're running high rpm muscle, or high torque towing applications. The old "AMC straight 6" had 7 bolt mains😳 and were also balanced from the factory. Those are the 2 main reasons most people speculate they were so bulletproof. Very little vibration.

That looks like a good piece I’d have been curious to see the rear crank flange they have a different shape depending on stroke I could tell you what cubic inch it is by looking at it

041 heads are same as double humps but with accessorie holes

Nice score!!
