I picked these up over the weekend. My 3.4 should be a very happy motor this spring. Has a 260H already in it, a 57 mm TB and some porting done, this should give me that little something extra when passing. I'll have the exhaust stripped and new ceramic put on inside and out and powdercoat the intake chrysler red like my valve covers. Then to have the car dyno'ed so Ryan can do fine tuning if necessary. Plan to make my first trip to Frazee this summer.

Nice find, keep us posted on your changes.

Welcome to the club.

A word of advice: get solid copper or aluminum gaskets for the header to y-pipe connections. Paper or composite gaskets will get eaten up in no time.

Do you have a part number by chance?

Here are the gaskets that I used: http://www.summitracing.com...sum-620125/overview/

As you can see, they're 2.5" ID header collector gaskets. The Trueleo guys use header collector flanges for the header to Y-pipe connections. That said, your headers appear to be a little different from mine. The size and shape of the Y-pipe is different. You may want to measure the ID of the flanges to be sure.

In any case, several brands and types of header collector gaskets can be found at Summit Racing. And once again, the solid copper or aluminum gaskets are your best bet.

Appreciate the link and information Blacktree, definately following your advice on gaskets.
