Well I am wanting to upgrade my exhaust this winter, any OSO advertiser's running a sell on some aftermarket manifolds to fit a pair of 454 mag mpi's with cap. call? if so how about some info on who has the deals going on!!!! thanks, also what is the best bang for your buck on manifolds
Mark R

I would have to say best bang for the buck is Revolution Marine

hey thanks for the link, I will check it out, anyone else?

thanks for the link, I am also looking at Gill and Imco, I heard that imco runs the water through the flange instead of a hose bypass will this cause problems

I am also planning on buying new manifolds, for a 502 carb. Maybe we could get a group discount. I am also looking at buying used.

stainless or Imco new,send me a PM

H2Xmark,

I have a set of IMCO Powerflow's with the short risers for captains call, all the brackets, hoses, belts, etc. to install on a Gen V engine.

If interested lets talk.

I bought a set from Dennis Moore, they were quite a bit less than Merc manifolds and are supposed to flow better. I still don't have the engine together yet, so I can't give an opinion on the performance. They were cost effective enough that I had them shipped from Cali and still saved quite a bit.

I just did Stainless Marine exhausts. The engines really run much stronger.
I actually lost speed on top because I can't keep 'em off the rev limiters. I have some new props to test next week.
The SMs sure were'nt cheap....

And... I have a leak on one of them somewhere... I can't find it too easy. I tried while the engine was at 3000 on the hose, but no evdence...
I know I have a leak because the water dries and leaves salt behind...

Please call me i have to check the price on monday but,we have two sets of EMI with ss risers for $1400.00
a set.
