hi guys

i have a ls2 corvette with harrop supercharger - this is a pic i found for the harrop supercharge

http://www.v8.co.nz/wp-content/uploads/2010/03/VZ-HSV-Clubsport-V8-46-eng-345x229.jpg

and i found a really cheap l92 heads so i was wondering would the supercharge fit the l92 heads? or i should do my own ls2 head which will not flow well as the l92

It will not fit. Perhaps you could call Harrop on see if you can buy just the lower manifold with the square LS3/L92 ports. Who knows how much the would charge though. Performance Inductions has heads that flow as much as LS3 heads.

What size is that blower? if I didn't have a big budget I would buy a set of used 317s and do diy porting and upgrade valves and get a big blower cam or have them ported locally if they can do it for cheap and get the cam. Just a suggestion.

I wouldn't do the heads without forging the bottom end first. You'll be approaching the hp limit of the LS2 stock bottom end.

Send your 243's out to Richard at WCCH and have him run his biggest CNC program through them.
