Didn;t see the 90% street part, sorry. :roll: There is an eye roll back to you. Then, if thats the case, i wouldn;t build a 582. I would build a 509, or a 532 with a 4.6 inch bore, if you want more cubes, which you won;t need. In which case, I would use a big custom high lift hydraulic roller cam, with good lifters, and the right springs. Crane lifters, will rev 7000. I know how most guys think, have been around this stuff a long time. I know he says 90% street, but, he wouldn;t be thinking 582 and solid roller, if he didn;t want big power. I know a mild 582, would give a huge kick in the shorts, but, I think he might be disapointed with the top end. It wouldn;t really matter anyhow, because in that car, it will never hook. Even a 509 makes crazy power for a street car.
Case in point, I know of numerous guys who have bought 502 and 572 Gm core engines, and, were totaly disapointed. Decently snappy on the bottom, but then are dead before 6000. So, it blows the tires off, then falls on its face because there is nothing left. I have revamped at least 5 502's, and one 572 after 1 summer for that very reason. One guy with a 572 in a chevelle got smoked by one of my customers, in his super budget 496, and was mad. They got to talkin, and I fixed it up. 770hp from 620, and it was no less streetable. The 502's get turned into 509's, and make 730 and 660 on the tq. Thats basicaly 225hp, from a cam, and porting the heads.
