We have used the Moroso block filler in all of our drag racing engines with good luck (Moroso part #35570).

If this is a GM block, you might as well not waste your time putting it together if you're going to run 30lbs of boost.

Use a better block or reduce the boose! Hard bloc is in my 2 motors but, it's not that critical on mine! WT:)devil

Jim I do not think you need block filler unless you are running mega HP and or Boost and a Dart block is already stronger than a stock block! WT:)devil

Hey guys, just reading through the thread, and wondering. What's the advantage of filling the block? Strength only?


PS> Is this used for drag racing only?

Darrell.
Darrell, Filling a stock block keeps the block from destorting under hard load and high RPM! Just my .02 WT:)devil

block filler

I have a merlin block, half filled. Recently punched a rod out, through the pan. Only issue with the block is a little more clearence under the cam rail. Little grinding to clean up, hone the cylinder and good to go. Money well spent.

tom i hope you learned your lesson on the last gm block;)tell billy to buy a good damn block so there is no problems:|errif not okay milkshake time again:p
its not my motor, i just put it down on paper and i'm helping with the build,ordering parts;) the block he's got is a highnickel 4bolt and sonic tested great, its never been rebuilt/bored(we took it to 60 over) and the mains are still super tight with the block.not to concerned about it, lots of guys doin it already for yrs. he'll be able to run up to 32-34lbs, but the boat will be ran on pump gas and 14-16lbs of boost 95% of the time.
