454 or stay with a 350? 74 K5 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was contemplating putting a 454 I was about to go pick up tomorrow into my 74 K5. A friend of mine who has owned several good 4wd Toyotas thinks the big block will be too much power and be a parts breaker. He has seen it happen a lot on the rocks and I plan to do some wheeling on the rocks when it is done. I am not worried about the gas mileage or anything just wondering you guys opinion on whether the 454 with a mild build would be toooo much power. I know I know theres no such thing right? lol

I also thought about pulling the 355 out of the 75 Jimmy and using it in the K5 and using the 454 in the Jimmy.
