The IAG 950 Short Block is the ultimate "weekend racer" block. Built to withstand up to 950 BHP, this is our strongest "Street" short block offering.

Each IAG 950 short block is hand assembled using ACL or King rod and main bearings. This combination of parts makes the IAG 950 the perfect block for drag or road racing.
