Block filler

[blk00z28]

I know the biggest pro and con of doing this. Makes the block stronger, but makes it run hotter. What are everyones opinion of block filler?

I'm gonna be spinning the motor to about 6500. Also running 4-bolt mains. Going to run studs rather then bolts just about every where I can to help hold it together as well.(including the heads.)

The psi I'll be running? :dunno: I guess I can say 25psi. Maybe a little more.. Depending on how it runs, or more of what it runs with my setup.

The blocks not going to the machine shop until I get the heads done(before Feb.). So any and all ideas will be helpful.

One off topic question, what extra holes have to be drilled into vortecs for bracks?

Re: Block filler

thats a lot of rpm for stock block. block fill has never helped me in stock blocks and it wont help with rpm. I would bet you have main bearing or rod bearing problems before anything else. I wouldnt waste my time with block fill. turn 6200 and you might get it to live for a while longer.

So John, its more down to the crank wanting to walk then the block giving?

If one were to 4 bolt it, and dowel pin the main's would that help? In no way do I have the funds to buy a bowtie, and then have it machined. That is unless someone had a very cheap block they didnt need..

I'm looking for some good, proven things that have been done to the stock block to make it stronger and live while making over 600rwhp.

pinning the mains isnt going to help. 4bolting it takes care of the bottom end as much as can be done. pining only keeps the cap from walking side to side. it does nothing to help keep the crank from pushing the caps away from the block. this is an issue on the front main as it's only a 2 bolt. stock bore size will also help. 40 over will not work and 30 over is pushing it at your hp level. you want as much strength as possible.

what is safe rpm on a built motor?ex.4 bolt main ,eagle rods,etc like most of us have.
