Is your motor together ? I personally would not run static compression that high if its gonna be a street driven machine..It limits the amount of boost you can run....I would drop it back to 9:1 static compression and be able to run a little more boost..while keeping the Bottom end Tq Respectable...I would also go with a cometic head gasket...Proper cam selection is gonna mean all the difference in the world...
what is your purpose with the engine,,Street or Strip ?....The Boost from a Blower motor is what the prize Treasure is all about...If you have a chance to look at a dyno sheet from one of these (smallest of blowers) I think you will find that the Tq Curve is what is so impressive about running a blower making boost...and why its most important to get the extra 3 or 4 Lbs of Boost from these blower set ups...
The HP increase is OK but you will appreciate the TQ the blower makes way more then the HP.
What your after with this blower is when getting it in High gear its still pulling your Nuts off at 80/100 mph
I too have a 144 B&M blower I have sitting in the shop.....also got The crank,rods and Pistons......
