marketed by dennis yes.. manufactured, no... i've looked at most of em out there... SM, imco, emi, gil, glm... i still have iron mercs... BUT for the price... you can't go wrong plus you will save some weight. (spell that 100 lbs).. as for actual HP / torque gains... well i don't know... no one has shown me any hard numbers... now a boating mag DID do a test... straight swap at the ramp on the same day.. stock motor... picked up something like 2 mph... for what that is worth

If funds permit.. i may pick up a pair to play with this spring.. i have a few ideas to help em out a bit more... they do seperate the runners more than the stock merc iron manifolds do but i feel i can improve on this...

but as i said.. for the price... compared to the other aftermarkets... can't go wrong... just to get rid of the iron stuff

ok someone blow some holes in this LOL

OR dump out some actual dyno comparisons for the sbc... i am ALL ears on that one! :)

Root - still skeptical

The GLM's that I bought are cast iron, so I won't gain any weight advantage. I just heard they brought them out in aluminum too.
