http://www.wbodystore.com/exha.....folds.html

Are the exhaust manifolds for a 3400 and a 3800 the same ? As in, will these fit in my 03 3400?

whats your opinion on being "worth it"
im planning on doing a full port job on my upper and lower intake manifold but wanted to do the exhaust first so i know it can breath out everything im trying to make it breath in

Exhaust manifolds are completely different on the two motors. If you are seriously interested in ported manifolds look into http://www.milzymotorsports.com/.

Honestly, the biggest bang for the buck mod you are looking at for the 3400 is a tuned PCM. It'll make it a different car for less than 250 bucks. Aside from that the cost of performance gains is ridiculous high. WhiteLightning04MC did a ton of work on his 3400 and he tends to suggest that others don't do the same.

haha don't cave yet, just check out 60degreeV6.com and research before making a decision. Yea you'll spend more money on the 3400 but you have to do it wisely, any fool can whip down some green and buy horsepower but it takes a real hot rodder to figure out how to make it.

Not to discourage anyone, but it's hard to justify extensive modification on the 3400. The aftermarket support is minimal, the gains are mediocre, and the engine itself isn't the tank that the 3800 is. One thing to consider, that's often overlooked, is gearing. If you're set on the 3400, swap in an HD diff to get the 3.29 final drive. It will require pcm programming though.

I traveled down the 3400 mod path and if I had to do it all over again, I would probably drop in the L67. The only real positive of the L36 is that I can't kill it, no matter how hard I try. LOL.
