8.1 liter risers needed
 

I'm needing 4 risers for my 496's

they made them in at least 2 different heights, which ones do you need?

im unsure but atleast 4 inch tall or more. I have room in engine room.

I have 4 of these, They are new take offs (never ran) with some shelf marks but nice. They measure 4" up from the bottom of outlet and 8 " to the top. Mercury wants over $600.00 each. How about $600.00 for all 4.

I have 4 black ones & a set of manifolds that I would trade for a 6" riser extension kit. Randy

I need riser (extensions) I guess. I have standard height risers but I need to raise them higher they are now lower than my old positions

Doug Russell marine has them on E bay for 750.00 I was hoping to find something less expensive. I was thinking about cutting my 4 risers & welding the bases together to make my own but haven't found anyone that wants to weld them. Randy

I picked up a set of the taller 10" risers on ebay a few weeks back for $250.... Used but in very good shape.... I got some serious paint remover and after 3 attempts got the black paint off and then spent about 5 hours sanding and polishing them to a mirror shine..... I had reversion with the shorter risers and no turbulators but the taller ones with turbs in with my 228/233@ .050 cam works good!!! TBF

Sounds like the OP is in the same place I am but 2" taller won't help me. I am replacing stock manifolds that had 6" extensions to begin with & went with 496 exhaust because it is lighter & breaths better for the upped hp I am running. Randy

There is a guy on the Donzi site that had a set cut and welded with a higher rise. I will check and see how they worked out and who did them.
