454 Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

cweber · 03-10-2011, 05:22 PM

So a buddy is tearing down his mud bogger and is wanting to sell me his 454. Its stock and runs but has recently develped a knock, so he is going back to his 350. He only wants $75 bucks for the complete motor minus the carb and distributor. My question is how hard and expensive is it to get about 500-600 horse from this motor? It doesnt sound like its that difficult to get 1hp/1ci from what i have seen. Any thoughts or suggestions?

Yes, it is not too difficult to reach 500 bhp from a BBC. But, in your case, I would have the block thoroughly checked. Good luck.

How hard and how expensive it is to 500 or 600 greatly depends on what you are starting with. Getting 500 is a lot easier than 600 out of a 454. Any ideas of what is in the motor he wants to sell you and how much water and dirt has been through it?

Try to get the casting numbers off the heads and block. If you can find out if it has a cast or steal crank?

I dont think its had any water or dirt in it, but Im sure some could have made its way in. Its just a bone stock from a 70s or 80s truck. I think I may have decided against it. I havnt even put 600 miles on my 350, and have enough trouble keeping the tires stuck to the ground.

Go big block. Always go big block.

So I told the guy no and now I have a big block in my shed. The research begins!
