I've got less than 75 miles on it, so I'm not getting on it very hard yet. So far I'm very happy with the performance.
According to Edelbrock's hype, it should be 400 hp and 412 ft./lbs. No dyno test yet.
Stock crank (polished), rods have been peened and ARP bolts were installed in them. Main stud girdle. Pistons are forged L2456 TRW's with the dome milled off, yielding a 10.3 to 1 compression ratio, a bit over Edelbrocks 9.5 to 1 test motor. Heads are performer RPM's out of the box. I'll probably match port them before long. Of course, it's been balanced.
