Some new ideas for my Slant

For the money invested in a long rod bottom end, you could buy a few other power adders(cam, headers, etc.), and make some decent power gains. The setup you described above won't have any more power or be any faster than a stock bottom end 225 with the same intake and carb, and a head milled 0.1".

The long rod bottom end won't gain you anything noticeable with the above setup, except a lighter wallet.
