Volvo themselves sold an alloy inlet like this one for a downdraught Solex/Weber in one of their R-Sport range of tuning kits. Rarely seen though.

That wasn't quite what i was getting at - rather than buying the bits ready made, have them made so they definitely fit, more for someone else contemplating a similar conversion.
Volvo did a tuning kit for the 740 which had bigger valves, higher compression and a VX cam couple with a 4-2-1 manifold and 60mm exhaust system - can't remember if there was an uprated FPR included or not but it boosted power from IIRC 112bhp to 136bhp on the B230F engine.
Bigger gains are likely to be had on the older B18/20 Amazon engines as they're not so constricted by emissions control kit.
