Boss 331

[DAVID GAGNARD]

I have the new BOSS 302 block in m racecar, it is a 331 stroker also...... Block is VERY meaty and everything on it is heavy duty and machined, a true work of art.................but,beware, they give you very little info when you buy the block and calling the Ford Motorsports Tech Line is a joke!!!!!!!!!!!!! They give you absolutley NO techincal advise on head bolts/studs, head gasket or anything else you ask them.....
And they ARE having "Some Issue's" with the 4.125 bored blocks, that's according to what the tech guy let slip..........

So what is the recommended head gaskets, studs/bolts, etc? I also believe the screw in soft plugs are sold separately from the block.

Roush Performance is about to release a new version of the CROSS BOSS engine. I have a picture of it in my gallery.

Screw-in plugs come with the block.....not only are the freeze plugs screw-in, but all the oil galley plugs are the same and all screw-in plugs have O-rings on them and correspond to the machined block for sealing........

There is NO recommended head gasket/stud kit from Ford, they refuse to tell you what to use!!!!!!!!!!!!!!!!!!

I used some 351-C head gaskets (Fel-Pro) and ARP head bolts, but I'm going with head studs now.......the block is basically a Cleveland block and you may or may not have to drill the steam holes in your heads if you'er using Windsor heads, just depends on which head you use.....most need the steam holes drilled in them!!!!!!!!!!!

Standard head gasket DO NOT cover all the water jackets, as this block had 8 extra water jacket holes in it, it takes a Cleveland head gasket to cover them, I found out the expensive way, cause once you open a sealed pack of Fel-Pro head gaskets, they are yours and Ford Tech refuses to tell you all this........................I now have two sets of unsued Fel-Pro head gaskets!!!!!!!!!!!! Thanks to the Ford Tech folks...........

Cam bearing are another thing, depends on the cam as to what cam bearing you have to order and they are not cheap......

If I had to do it all over again, I'd go with the Dart block.......it's a little more expensive (about $800.00 worth), but all your Windsor stuff will bolt on, cause it's a Windsor block...........saw one at the machine shop I use and it's every bit as good as the BOSS 302 block!!!!!!!!!!!!!!!!!!!!!!!!!!
