Dan, the 345 horse 454 had the low lift hydraulic cam...I believe the same one used in the 325hp 396 motors. If this engine has the rect.port heads and 569 intake, then perhaps the cam was upgraded too. Since you said it was a running engine...does it sound like solid lifters..?? Since you mentioned the block was decked you may find that someone used the 2 bolt block and built it to LS6 specs...

What kind of vehicle is this 454 in now..???

the motor is in my friends 1970 Chevelle SS 454 LS6 car.
it does have solid lifters and cam.
we are trying to get as much info as we can as my friend will be searching for a 4 bolt main block soon and may want to take this block out and sell it. we clearly know it is not a matching motor to his car but if he pulls this motor out he wants to be honest in telling people what it is if he plans to sell it. i would really like to know were that Vin# would belong knowing it came from a ST. Louis Plant.
i also popped the valve covers off and both heads are different,one is a 3919840 D-3-8 and 3964291 F-6-9.
the only piece that matches his car is the correct low rise GM intake.the carb is a 3893229 3613 653 from a 1966 motor.
so as you can see this motor was pieced together but it does have good components to sell or trade off.
