Low Mileage Hydraulic roller 360 LA and $1000.00- what would you mod?

Cam is usually a good start. I'd keep the LSA above 108 and the lift around .500 or below. Port and polish, with some springs goes a long way for heads. Aluminum dual plane intake will help keep it streetable and it'll lighten up the motor quite a bit. Oh and a 700 dollar cold air intake filter goes with out saying.
