its the same way with my vettes, go twin screw if u plan on staying blower exhuast tune "stock motor" it will be fun down low and it will make the power u want, if your looking to do a good build on the truck , forged internals ect go with the paxton it will make close to 950 hp if you want it too. for an example i had an 04 cobra with a whipple which is close to the roe both twin screws anyway the car pulled like an ape until they hit top end area and fall on its face due to internal boost bypass valve letting the boost out, the centri or paxton if you will shines up top and will make more peak hp in those areas. ive been through this debate alot and ive had cars and trucks with both. both systems have a belt so there will be the phrase " takes power to make power"
