I have a 1998 C70 engine B5234 T3 with a spun rod bearing. I would like to replace the engine with a later year 2000 or up but I've been told the only engine I can use is the same year as I have and the same model. The manual shoes the engine B5254 T I guess as an alternate at the time of purchase. Which engine is better if I stay with the same year and, is it possible to use a later year engine instead? I'm a big block Chevy man at heart but I do love my Volvo C70 and would like to install a cam and headers and a few other things just to boost it just a little.

Thanks in advance to any help or information I can get on this My Volvo is in the garage now and it's breaking my heart every time I look at it.
