I think the next big thing for performance is long tube headers. I have heard of an extra 40hp with them on a 55K engine. I think you can only go so far until you have to deal with the fact that the exhaust manifolds are a great big cork in the system. I have found someone to make them. First set would cost more at about $2,200 and then go down with more orders. Shorties are worthless. Long tube headers with high flow cats and 2.5 - 3.0 inch exhaust would go a long way. On the 55K engines the gains from just the headers were much greater on modded engines than stock 55K engines which proves that the exhaust is holding you back.

I love the 3.7 idea but you have to be careful with cams on a s/c engine. you need to keep overlap lower on a boosted engine. I can't remember the name at the moment but on of California's oldest cam amufacturers will re-gring your cams for a very reasonable cost. For a V8 the SLR cams can be used in the 113 V8
