DART SHP BLOCK...
I know, it's NOT LEGAL...right ? car is a 1971 LT-1 Corvette convertible, Ontario Orange, black gut. Just for more info, the SHP block does not offer an advantage as far as cubes go(as oppoesd to a production 400 block)-but it is stronger, has improved oiling, splayed caps, and is made of iron. Just checking.

Re: DART SHP BLOCK...
2.00 ENGINE
2.01 Engine block must appear to be a correct* original block and it must be an original vintage OEM or vintage OEM replacement of the same engine family and exterior size and must be made from the same material as the correct* original block. Also, a new OEM replacement block is allowed only if it duplicates a legal vintage block in design, material, appearance, bore size and performance. No aftermarket blocks are allowed. Replacement OEM blocks that have raised decks, raised cam or bigger bores are not allowed. Block casting number does not have to be correct*. NO AFTERMARKET BLOCKS ALLOWED.

Unofficial 11.67 @ 117.69 1.74 60'
If your not breaking or running slower your not trying.

Re: DART SHP BLOCK...
So, if I want to run a 400 block, does it have to have only 2 freeze plugs instead of the more common 3 ? When the engine is in the car, it's hard to see the plugs so is it a case of "out of sight, it's allright" ?
