Weber Racing has for sale a bored and stroked 4.1 short block. It is fully blueprint CNC machined, has an all forged 3.55" stroke, 4" bore, 6" rod internally balanced rotating assembly, and is capped off with an RJC girdle.

For more info go to Weber 4.1 stroker short block

I only have this one right now. If I were to start now and build another one it would be approx. $1,000 more.

The 3.550" stroke is too costly now that all the other stroker parts are available so I am not going to make any more. I had to have 20 sets of rods made by Manley to get the cost down and it was still expensive. Then 3.625" parts became available shortly after our 3.55" stuff did and with some people whoring the stuff out, our parts started moving slower. Bottom line, no more 3.55" for now.

Sorry.
