My rebuild is finally leaving Arrow Racing today ....the final numbers on the dyno were 645.4 hp at 6100 rpms and 613.2 lb-ft of torque at 5000 rpms....obviously this is on a full exhaust with no cats as the engine isn't in the car....I'll have to get it on th dyno in the Spring to get some real world numbers....

Gilly,
Very impressive numbers. If you don't mind answering, what precipitated the need for the rebuild?
Thanks,

A little Gen III to Gen IV comparison on my rebuild I just got back. Same dyno and I assume it's inside with the same conditions.
I got 546 hp, so right at the expected 100 hp difference.
I got 578 tq, which surprises me compared to yours. Only 35 difference.
I was actually stunned when Todd told me the tq numbers for mine!

Not yet. Still waiting to get the car back. They are still having delays at the dealership with being short-handed, but I also backed them up about a week and a half by having to buy headers. Should get it back this week.
