That cylinder is huge :bigeyes:

 

[Freestyleriverrat]

I think the whole kit (cylinder, and head combo) is a little over 2 k w/o sleeves or pistons. Probably close to 3K all ready before you hear it fire. :boggled: Cool cylinder though.........if they would just make some billit cases :tomato:

I think the whole kit (cylinder, and head combo) is a little over 2 k w/o sleeves or pistons.

It's $1,995 with the sleeves (not installed). It'll be well over $4,000 for the complete longblock by the time you add it all up.

Thats right......I remember reading something about the sleeves not installed. Still..............this has been stated seveal times...........I would hold off until you hear or see this motor run. The porting on this cylinder will make or break its performance as will carb selection.

At what point do the transfers fail to deliver enough fuel to severely lower the effiency of the cylinder?

I have no idea.........I am mainly thinking in terms of bang for you buck as far as power is concerned.

 

[cambo au]

with all those extra cc's do the factory b pipes still work good considering they were made for 701cc motors just wondering?

 

[waxhead]

I htink they would cambo
you may need to increase the size of the stinger
to help pull some heat of the back of the piston

 

[cambo au]

so do you get a different pipe or modify the factory b ? dose the tnt have a bigger stinger?
