We have guys running b lowers and turbos on the new style Sportsman block with the 2 bolt caps and making 900 HP. These guys have there engines tuned well and have not detinated the engine. Ford called the other day and said the current Sportsman block has been given a new part number and a few changes have been made for the better. I will have to waite and see. we had to cancel the Sportsman blocks we did have on order and order more under the new number.
We have plenty of guys running the Windsor blocks up to 600HP. I would watch turning it 7000 very often without internaly balancing. We will hold the 408 engines to about 6700RPM with the factory 28 oz balance set up. We have been using these blocks for a long time and have had real good luck with them. Thanks Keith
