best place for 340 parts?
Well, the best deals in general are summit and jegs racing web sites though you can also do well by snooping around.
Often I find myself at Mancini racing .com
Only the "ME-2" Chevy engine is cheap since everyone that follows the jumper off the bridge has one.
Seriously, only certain parts are a bit more expensive than the ME-2 engine and most other parts are just a few dollors more at worst. Sometimes, we get away with lower prices on things.
Oh, theres a good following in your area. Give a shout out.
