Thanks for the info! Can you help me with this front casting number on a sbc in a 83 el camino ML25353. Supposed to be a 350 but doesn't feel like it

Questions?how do I find out what horse power it is?

Alright: gotta block that, when I search the number, pulls up three engines with the same number. The guy we got it from says it’s a 327, but the three engines that pop up are a 350, 327, and I believe a 302. How do I figure it out?

Same block I have, was actually like, what the heck that’s what I have 😂

No that’s not as easy as that. If you’re a good engine builder you help identify these completely. This would be a much more helpful if you could tell people how to identify the production number on the front of the block. Some blocks like the 327 and a 350 had the same casting number, such as 3970010. To find the exact year and identify weather its a 327 or 350. Someone could sell you a 350 and it’s a 327

thanks, I saved the page into my favorites

Zane, this video should open my eyes to a wealth of info... Going now to search for this.
Thank you.

Thanks bud!

Thank you for posting!!!

My dad let me have his 85 squarebody chevy and the original motor was swapped out I think a 350 was put in but will use this to double check👍🇺🇲

How to... use Google 😒

thank you for posting this video, i spent way longer than i care to admit looking at pictures taken from 2" away from the block that didnt give any idea as to where the number actually was on the block. watched your video and was able to find my number in 30 seconds

Hi, my dad bought a motor, but the number is different, do you know how can I find out? Thank you for the video.

High nickle block

Not even one of them started with an 8

thank you most excellent video i know what my engine now a 96 up 350 cheers bud

Mine comes up as a 302/350 how can i tell the difference?

Was told my engine is a 350. It’s in the car so hard to see some of these spots. The front pad is Def shaved off and the back I can’t even locate an overhang like yours. Any other ideas what I should be looking for and where??

400s are simple to tell they have steam holes between the cylnders and splayed main caps

That be a 400 small block

Great info. thanks.
