Boss Block and Stock Heads

SSGT Mustang · 02-23-2018, 01:16 PM

How many more ways can Ford screw up a good thing? They made a great block with great materials and bulked it up in the right places but decided to shorten the bores for all the wrong reasons and there's something else that they screwed up.

They put scalloped water jackets on the outside of the deck so now you can't use a production heads on the block. The lip of the water jackets are uncovered with the stock head. That was never a problem with the R302 block. There were round holes drilled on that block. If you needed to you could just plug them.

I don't care who from Ford Racing comes on here and spews some reason for this stupid design. They just gave away business to Dart that did their homework and probably looked at heads and asked racers what their blocks should have and should not have.

At any rate, has anybody managed to make the Boss Block work with production 302 heads? I would be grateful to learn how since I now have a $2000 block that is worthless for stock and super stock.

Thanks. I've been a Ford man for 40 years and they just seem to go out of their way to make it almost impossible for drag racers to compete. They've been doing this forever. I don't know why I still bother. I mean why do they bother offering up a great new block only to limit its use. There is NO reason to do what they did with this block other than make it easier to do their stroker crate motors. To do what they did to the water jackets is special kind of stupid. I've have G-Blocks, R-Blocks, production blocks that never had a cooling problem. I have R-452 block from a winning nascar team that has round holes for the water jackets. What does Ford do? Create a new block and screw it up with stupid design "ideas."

I'm just baffled by it.

That's good to hear but I put the heads on the block and there's water jacket openings as clear as day with an E7. It's not much but its there. I cant see how it would not leak since there's no head surface to seal the gasket to the block.

Since Ford made this great idea you would think they would make some kind of expansion plug for the holes. I may make my own punch and die but Ford should have already done that.

Ok just relax i had the same thing happen to me. Filled it up on the dyno poured out i looked like idiot. Had a machine shop put cast iron rod pressed in the block to fill those holes. Cost me $600 i think but all has been good, this is a stocker with e7te heads been this way for years now lots of runs on it. In the catalog there is fine print about this didn't see this till after the fact. Have pictures on an old phone can send you. Will be a couple of weeks till i get home, racing in Arizona right now.
