One 1957 283 hp block with caps and heads. These are the real deal 100 % guaranteed not a re stamp or a modified passenger block. No funny business this is the actual real mccoy. FYI..Just because you have a flint block does not make it a corvette block. 

I think this would be for a 1957 corvette made in spring of 57 going by the dates

No repairs or damage great cores on an extremely rare original part

I have seen many " so called" fuel injected cars with fake or wrong blocks or real cars with wrong engines. In fact more fuelies i see have incorrect blocks than not. Many are flint car blocks with an extra letter stamped after the car stamp. Many will even try to say that is correct. It is however not correct. GM used proper gang stamps and NEVER factory stamped extra letters after a suffix, there was no need to. The stamp was applied after assembly.

Odd thing is there are now 4 times the amount of fuel injected cars than were even produced. You figure out how all these cars are numbers matching makes sense if people are turning flint car blocks into corvette blocks. Well enough of my rant.

Make your original fuelly correct with these great original correct numbers and original stamped pieces.

So these are an original EL block and 539 heads in case its not clear in pics

Please note: Shipping calculator is not necessarily correct. Shipping is as it will be calculated at auction end and the actual cost to ship will be the responsibility of the buyer to pay based on their choice of transport. Pick up locally is of course  an option

Shipping to US and/or Canada is fine
