I am in Nanaimo BC. I bought and installed gm part #19210007 330hp engine, based solely on the fact that I was promised a 300+ motor. Am I wrong? This motor idles worse than my 25year old 305. As for horsepower I suppose the best thing is to dyno it and then have them explain?
I have no idea about the idle set, it was a GM dealership and mechanics who did the install are they not the experts? Apparently not, that's why I posed the question. No vacuum leaks. No tach, guessing 700-800 rpm when idle is right, 100 when is stutters.
Have a 1989 c1500, had a 305 tbi. Bought a new crate motor 350 ho base motor and was told it would give me my 300hp with a throttle body setup. When I picked up my motor I was told that the idle was not right, now 2.5 months later it still does not idle correctly. Have been told everything...
