Block Filler

I want to give my block the utmost strength i can give it, so i plan on filling it as much as i can and still be streetable. Ive heard several ways to do it, only two inches from the deck surface, some say only to the bottom of the water transfer ports at the front of the block ( thats what im leaning towards ), or only a little bit at the bottom. I am not worried about excess heat, the truck is getting transformed into a really really hot street truck/toy, no prolonged heat soak or towing will go on. I might need to add another oil cooler as well, Air to oil. Ive heard Hardblok is the stuff to use, is there any special way to do it other than torque down the mains, fill one side, sit level, torque down the head on it and let it sit for a day or two to cure?

Thanks in advance

Re: Block Filler

on all the street rods we put the piston at bdc and fill to the bottom of the ring's stroke. that will leave enough water in it to cool the rings and cylinder, oil should help cool the piston itself

Re: Block Filler

The coolant won't run 1 degree hotter with the block filled almost to the top. And the oil should only average a few more degrees. Maybe like 5 - 10 degrees average.

It's not a big deal.

Re: Block Filler

Could you get away with just filling the block and running main studs without a girdle for a hot street truck.

Thanks for the info golfer! Didn't you guys run the heater hose port from the rear most ports on the heads? I thought I remember reading something about that?

Re: Block Filler

we added a coolant hose to the rear of the drivers side head (near #8), and tee'd it into the inlet to the water pump.

after the block is filled, you do need to drill/chisel out passages at the front of the block, and vertically at the rear of the drivers side (inlet to oil cooler).

just make sure that the coolant being pumped into the front of the block can go UP into the heads () and then back down through the heads, and into the block at the oil cooler.

take care~
