Just received 2 big bore Shelby blocks. These blocks start at 4.375 for a really big FE project. These big bore blocks relieve the valves for better flow on the engine. These should work real well with some of our 427 Edelbrock CNC heads with the 2.25/1.75 intake valves. Might even be able to run some 2.300 with these blocks for some real good HP numbers.

This is the first 2 blocks we have received from our 10 block purchase we made about a month ago. we have been waiting for Darton to get the sleeves to Shelby for the standard bore blocks. These large bore blocks are a 500.00 cost upgrade to the block, but not that much if you want to build the ultimate FE project engine. Thanks again
