is this carb any good... im looking to buy a blazer and im not sure if i want to get a fuel injected model. or get something cheaper with a carb.. i have used edelbrock and quadrajet and when hillcliming they bog out... i do alot of trail riding.. im skeptical about these holleys.. but i dont know how good a tbi chevy will hold up to lots of trail riding.. any one who has a truck avenger tell me what you think..

plus anyone who has a tbi chevy, how do these hold up to offroading..
