I'm seeing the stamp as having a "KB" suffix. The picture isn't real clear for me. That would be a 396/350 hp with 4bbl carb and manual transmission from a 1969 Chevelle or El Camino per the Lime Book.

 

Awesome thank you I was wondering what car had this motor. The seller told me he bought it from someone that had it on a 69 Camaro RS.

 

Now the next question would be is it worth rebuilding this engine or stroke out my 350 that i currently have in the car ?

 

You can easily make 400+ hp by just rebuilding with the correct components. Is there a V8 currently residing in the engine bay?

 

With the changes needed to convert the BBC it would be much easier for stay SBC. A 383 400 HP is an easy build.

plus you save the added weight of the BBC and no worries about needing to change the front springs.

 

Am I the only one that sees the stamp suffix as TKB?? If so, that's a 402ci from a 1971 or 72 TRUCK.... not a '69 Camaro, and rated at approximately 300HP.

 

I'm with you, Delco115, T0219TKB

 

The bar of the T is debatable as it is not clear. If cost is a factor probably cheapest to go with a SB, but the BB has always had a certain "Cool Factor." in a Camaro.

 

TKB as well. That is out of a 1972 C20 or C30 with and AT. Originally 210HP.

 

Do you have a target budget? Either 396 or 383 can get you north of 400hp. What tranny and rear end do you currently have?

 

Stroker small block all the way.

Just price up the right pistons and heads for the big block and add in for all the accessories, mounts, pulleys you need to do the swap....The $$$ 396 big block looses fast.

LS motor swap starts to look good after that exercise.

383 is cheap when you look at the numbers.

 

A 355 will get you 400+ hp and TQ with a fairly mild cam and a set of modern heads, at least mine is per dyno sheet. 383 even more.

OP, consider cost against building your current 350 and a long block from BPE. You likely will be $ ahead on the later and have a 1 piece RMS, full hydraulic roller cam, 4 bolt main motor with modern AL heads.....and a 50k mi warranty.

Transfer your current accessories, intake, carb (600cfm min), dizzy to the crate motor

 

My 1970 402 has that block casting number, the casting date code will be on the opposite side of the block. You may want to post a pic of that. Not sure if they changed the block casting number when Chevrolet went from the 396 to 402. I think it's a TKB because they didn't use "I". It's your car so do what you want to do. If I had to do it all over again, I would not have gone down the big block road. It's heavier, everything is more expensive and you can build (or just buy!) a small block that makes just as much, if not more, power. There is the "cool" factor but that is ENTIRELY subjective.

 

Thank you all for the reply. Yes it’s TKB I thought it said KB but nope. So it’s a truck motor then. I actually post it up for sale for $500. I’m going to sell it and build up my 350 if already has work’s sportsman heads and Holley efi sniper
