Looks like a good plan. Just remember to do one change at time, and three passes to validate the change. I think the 5500 8" converter would be best. Try the extensions before change headers.Charvelrhoads wrote:Thanks for all the support and Ideas. I will probably get some bigger heads, but before I do, there is a few things I can try that won't blow the budget. First thing will be to recheck and set valve lash correctly, it appears I've been doing it wrong, so we'll eliminate that possibility. Next is collector extensions. Also as 408 Nova suggested I can try some carb spacers. I also have in my possession two more TSI spragless converters, an 8" that is supposed to stall 5500, and a 10" that is rated at 4500. I can try both of these to see what they do stall at, and if the engine likes them. I also have 1 3/4 headers that fit the chassis that I can try. I was thinking about changing the intake, but after having another look at the dyno pull Chad posted, I can't believe that it would be the problem. So it's bigger heads if none of this works. Thanks again,
