what 454 is this?

[1967 Impala]

Could also be out of a Monte Carlo..the SS 454 had the LS5 as an option did it not?

But did they build Montes or any A-Body cars at a St. Louis plant in 1970?.

Thank you guys for the input.
My friend has decided to leave this motor in the car,he figured why waste all the money and time to take this motor out and then find an LS6 motor and components when in the end it will still be a non matching motor car just the same.
but it would be still interesting if someone can answer the original question of this thread.
...Vin# on the pad near the oil filter which reads 10S189855 which breaks down as 1=Chevrolet 0=1970 S=St.Louis plant and 189855 Vin# (to which Chevrolet model would this motor belong to?)

1-i am pretty sure that 1970 Chevelles or Monte Carlos were never built from the St.Louis Plant so there out of the picture.
2-also the Vin# is to high for a 1970 Corvette.
3-does anyone here have a 1970 454 Impala to share the Vin# so i can compare it to the above one.

Unless I am missing something and based on the VIN alone it could only be from an Impala or Caprice and either a 345 or 390 horse.

I went over to Team Impala and asked the only member of a 1970 454 Impala on that forum about this motor through an email.
He did respond telling me that it is actually a 1970 Vin# for a 1970 Impala/Caprice or Station Wagon.
he also told me that in 1970,the production for the LS5 in an Impala/Caprice or Station Wagon were only 2,459 cars,this is the combined number for 345 HP + 390 HP LS5'S.
There was no SS in 1970 for the above models.
pretty good to know that the motor is a rare one for an Impala/Caprice or Station Wagon guy.
Thanks guys for all your help,i have my question answered.

Update from above post.
there were 2 different 454'S in the St.Louis built plant for big passenger cars (Biscayne/Caprice/Impala/Station Wagon)
1-LS4 345 HP production total 14,280 units
2-LS5 390 HP production total 2,459 units
=for a total of 16,739 units

There really is not that big of a difference in the LS4 vs. LS5. The comp.ratio, heads, are the same.
The Cam and Rear Gear ratio were different.
Rear gear: LS-4 2.56 LS-5 2.73
Cam shaft: Lift: .3983 I-----.4300E LS-4
.4614 I-----.4800E LS-5
The distributors were different also,with timing being a 2 deg. difference.

thank you Dale from Chevellestuff
thank you Graig from Team Impala
now i have it figured out
