It depends on what class you want to run it in. Twins usually put you in the modified class depending on the organization you pull in. You can still go on the street with a 2.6 (66mm) class pickup. With that much fuel, a P&P head and a cam you will spool it alright. A Silver Bullet, S366, or 66mm S400 all fall into this category.
