Please note

Listing in classifieds is for Paid Members. If you can't see the link to click to post an ad it is probably because you are not a paid member. There are no commercial ads allowed except by site sponsors. All for sale or trade ads need to have a price. No listing for offers only, but you can list something with a price. Ebay is allowed as long as there is a "buy it now". Potential buyers can inquire about the item being sold. If the sellers description has an error or not accurate you should PM the seller and or notify a moderator. No negative comments in the classified sections. We all have opinions, but we don’t need to bash people for placing an ad that doesn't agree with our idea of value etc. Members should be able to place an ad without worrying about being bashed. Members listing items or vehicles are expected to stand behind their sale or risk losing classified privileges and possible access to the forums. We want this site to be a place to be able to trust the person we are buying from. The seller & buyer are solely responsible for the terms and conditions of the transaction.

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

Kurt
