1970 454 Big Block LS4
 

I have a 1970 LS4 454 for sale. From the research I did this is a 345HP motor out of a full size car.

The block and heads have been cleaned and pressure tested. The cylinders are .030 over right now and need to be punched another .030. The heads are unmolested and need to be gone through. The crank is .010 under on the main and rod journals and need to be taken down another .010. The intakes heat shield came off during the cleaning process and would need to be replaced.

It appears the crank is a 1974 but I cannot confirm it. Maybe someone here can let me know.

Here are the casting numbers and dates:

Block: 3963512 D.7.70
Heads: 3964290 C.4.70/C.5.70
Crank: 353039 I or L.24.4
Intake: 3955287 D.15.70

$2000

I can deliver to the MCACN show in November.

Thanks SYC

What happened to the crank? Did it get shot blasted too?

No, this motor was sitting in a basement that had a LOT of mosture in it which made the crank rust badly. When I talked to my machine shop they told me that .010 would clean it up.

I am open to offers. Otherwise it might accidently turn into a 427! https://www.yenko.net/ubbthreads/imag...ns/naughty.gif
