V8's inna rear drive Volvo is the logical cure for that faithful B21,23 that gives up the fight, the dead diesel, and for adding spice to an old friend.

I discovered folks stuffing V8's in the Swedes back in the mid 90's, just when Converse in Maine was starting. A friend and I built our wives one 740 diesel with 2.8 GM V6/700R4 and the other a 375 horse 350 Chevy 700R4, both w/ stock rear, suspension, radiator and each a tractable, dependable fun car to drive.
Next in 1996 was a 86 760 X-Diesel w/ 302 Ford " Cop Motor", mild RV cam,AOD Truck, 3.73 rear, and I still have this sweet ride, not a rod but a cruiser, getting consistent 24 in town and 29 at 75mph here in flat florida. I do believe the fellow w/ the LT-1 / 6 -speed has the E-ticket though, I lust after that combo--or--the Ultimate Guy in Callie who wrote in last year w/ the 940 wagon had the LS-1 and 6-speed, telling that he had meet NOTHING on the road that could take him, and the kids ALWAYS wanted to ride to school with "Daddy". Love a "sleeper" and the VoVo8 is all of that. Best Regards, K.O.
