Revolution Marine. -- Works Awsome! I have used them three times on small block boat projects. I usually gain between 200 and 400 rpm, and they are a heck of a lot lighter.

Very light, great warranty (havent had an issue but it's nice to know it's there), I had to get the custom full length tailpipes but if you're running a big cam they're good because the water enters the exhaust stream only a couple inches from the tip.

GLM makes an aluminum manifold that works pretty good for the price. Dennis Moore sells them for around $600. Check his ebay store. I installed a set of Revolutions on a 6.2 for a customer. It picked up about 10 HP on the prop shaft dyno. None of them give you much power increase.

bobl, was this on a stock 6.2? What is your opinion on the Revolutions (fit and quality)? Any idea on the weight savings? Sorry for all the questions but I respect your opinion from reading other threads of which you contributed. Got a 292 with twin 6.2's and contemplating an exhaust swap. Sorry for the hi-jack!

with hp you guys are talking about you will need to be carefull about water revertion, the rev marine only offer a standard cast riser that will revert water for sure. I would look into some eddie marines with hp risers, cheaper isnt always better when your fixing a motor water got into. check with diamond performance they quoted me a great price on some for a big block.
