douellette Posted September 30, 2010 Report Posted September 30, 2010 what would be the best upper/lower intake to use on a 99-03 3400. i currently have a set from a 99 3400 van motor, is there a better choice out there or no? Quote
RobertISaar Posted September 30, 2010 Report Posted September 30, 2010 all 3400 UIMs are large-port, but it seems the latest ones(02 and later) had better castings, and didn't have the weird crease that the early ones do on the underside. Quote
douellette Posted September 30, 2010 Author Report Posted September 30, 2010 so should i try to get rid of the set i have, and find a 02+ 3400? thanks. Quote
RobertISaar Posted September 30, 2010 Report Posted September 30, 2010 the difference is VERY minimal, but if you're looking for every last drop... http://wot-tech.com/shop/articles/choosing-3100/3400-manifolds/cat_64.html that is actually a better resource. Quote
