What do you guys with 482's run on the street. Want something in the 625 to 640 tq range on the street

Benny, I have such a motor rebuilt by KC last August (after a rather dramatic rod bearing failure on the track). New Pond Al FE block, 482 stroker steel crank, H-beam rods, blueprinted
oil pump, and 10 qt AVIAID pan. They put in a 242/248/110 roller cam, redid my Edelbrock Stage II heads, Erson roller rockers. It makes 591 hp at 5600 rpm. 604 tq. It has a 750 cfm Holley 4150HP.
Nice mild street motor (compared to some of the 482s). I think the compression is about 10.5:1. But ... these FE's are still beasts, and if you want all the HP/TQ you are talking about, you really don't have a street car. It will be an amusement park ride for sure
Suit yourself .. I would not change mine, but do take it to a track before you take it to the canyons
Just fyi, mine does not run smoothly below 2000 rpm. So driving at low speeds in parking lots, away from a stop, etc. requires a lot of clutching and reving to keep the motor spun up. It comes up on the cam at about 3000, then it had better be pointed straight! I really could not use any more HP, the tires won't stick in any gear as it is. Soft tread compound is your friend
No street tires, use Billboards, Avons, or (Nitto NT01's if you have 17" rims). Good luck!
