<VV> Fwd: 140 Performance Upgrades

[Ray R. (aka Grymm)]

Indeed Joe you are correct...   neither webers nor a custom build by someone 
like David Clemens are in the budget right now...  I'm happy with what I've 
got but I want to build myself an early model coupe (either with the car I 
just bought or one that will follow in a year or so) and I'd like to take a 
different approach with my next build.. at least to give it a shot.

For me a big part of the appeal of my 140' Corsa's is the FACTORY 4 carb 
setup.. its just cool.  That being said I would not likely ever put anything 
else in one of my Corsa's....  sure.. mods are fine, my engine room looks 
far from stock... but the basic setup is still the cool factory four carb 
rig.... on the other hand my EM monza coupe didn't come with four carbs from 
the factory....  so it's open season on engine mods for that car!  I'd love 
to put a weber setup in that car...  I just have to decide which bank to rob 
first <ggg!>.
