Sounds like my F150 with 5.4 engine - you have to remove a bunch of pieces even to see the top of the engine - and the plugs are coil over which I believe your 'vette may be as well. Think about it this way - you're paying for (an) experience (yuk, barf, hak-hak).

If it's the ol' standard 350 with HEI, they saw a man with money - he has a 'vette and is loaded !!
