ill take pics of it tomorrow to show you guys whats going on with the headers.

I still say go with the turbo diesel like the Grand Natty

Eric, I used the headers from the 350 I sold you on my LT1, and they bolted up just fine. I know my headers on the front flanges have two holes, and I had to use the hole closest to the tube and the rest of them lined up just fine. To my knowledge, they don't make special headers for that application. Your 406 headers should work. If you don't have that inside hole, you may have to drill it.

In my opinion, don't go with the 8.1. Its basically a larger displacement 454 with coil per plug ignition. They are decent in stock form, but not performance engines by any means. A good friend has the 4500 with the 8.1, and it makes good low end torque but thats about it. It has about 12,000 miles on it and it already burns oil and has piston slap when cold. Also, I know someone else with a motor home that has the 8.1 (i forget the mileage) and it consumes quite a bit of oil, along with the piston slap. From what I understand, it was a common issue for these engines. Similar to the early 5.3/6.0 truck motors. I believe due to the piston skirt being too short?

ok thanks for all the info i actually ended up selling the monte

now you can put all the money into your 98! yayyy!

lol. not all but some. i have a few more items i want to sell but ill probably get an intake manifold long tubes catted y and some more suspension

sounds like a good plan to me
