expecting too much??
One other thing. I have a vig 3600 converter in my car temporarily and I'm really not impressed with it. I had a Yank SS4k converter that hit much harder and pulled better on the top end. I know that I gave up .05 in the 60' and .15 in the quarter as well as a solid MPH when the vig went in the car. I don't know how your vig behaves, but I know that I will not miss mine when the Yank goes back in.
The 98 heads aren't the greatest either. I have a fresh set of ported heads with big valves for sale cheap if you're interested.
