Thread: How much is to much?

Tweet

For the purpose of stabilizing the bottom of the cylinders, how much block fill can i get away with in the water jackets of a 351W and still have decent cooling for the street????

depends how much extra you plan on doing to the cooling system.... i've gone about half way up and had no problems............ but i also put a lot into the cooling system..... i know block fill is a cheap way to stabalize the block.... but have you considered 4 bolt mains and a girdle? it cost a bit more..... but it definately helps

i run them 1/2 way up alot of the heat is about 1 inch down from the deck. but they seam to heat soak 1/2 filled but it will help the block tie in the bottom of the bores and oil pan rail from flex were more bolts in the bottom of the block just make for a weaker block .short fill and girdle with good grade studs you should be good for some HP i do not know on ford decks but i have plug the deck up with soild iron pipe plugs and drill them out smaller to the size of the holes in the head gasket then i deck the block this help s alot to

Thanks Pat. This is for a Windsor. Just came up with an Enderle front cover, now it's time to start planning a cooling system to go with it.....

I will run splayed mains, but the bottom of the block still tends to move around a bit.... Just wanting to tie the cylinders and webbing together a bit tighter.....
