I acquired a set of Chevy 350 heads (cast # 14101083 = 87 and up 285-300HP with 64cc chambers, according to my research). To my knowledge they are stock, but have been rebuilt recently and visually look new. I have purchased a remanufactured 350 short block from Autozone (to arrive Dec. 5). I'm assuming that the cam will be stock and the block a 2 bolt main. Without modifying the heads, can someone recommend a performance (street) cam. I'm also using a Edelbrock performer intake and Holley 600 - 4 barrel with electric choke. Any other reasonable/inexpensive (after all this is the holiday season) performance suggestions will be much appreciated. This will function as my driver/cruiser while I save for something better. Thanks in advance for the info.
