Instead of using a Goodwrench 454, find a BBC with some performance parts and add a big shot of nitrous. Big blocks love big power adders.

let's not start this again. its illegal to put an older model engine in your vehicle. daily driving with a 454 will kill your wallet in gas even if its fuel injected. you will see better torque and horsepower curves with the 6.0. its not done because it actually working backwards. leave the stock motor in unless you plan on running 12's in that van.

It is not always illegal to put an older motor in a newer car. In some states you are only required the emissions that were present on the old motor.Originally Posted by cjriojas
The OP stated he wasn't worried about gas mileage. A 454 with good parts will eat a 6.0 for lunch and come back for seconds. Some of you are too caught up trying to find other trucks to race at stop lights on the street. All you know is the late model stuff. The late model big blocks weren't very impressive. But you need to get out to the dragstrip and see what is running the quick times. There might be a few newer motors running well, but for the most part the cars running the quickest times are still running big blocks. For every 10 second LS powered car, there are many more cars with BBCs running 9s or quicker.
The name of this section is "V-8 Conversions". It is for small block and big block swaps (stated right under "V-8 Conversions"). I don't think it was put here to talk people out of a small block or big block swap.

The difference between winning and losing, is having a 2nd stage.
FWIW, in states that have emissions regulations you cannot put in an engine older than the original vehicle. If GM has not put a 454 into a light duty truck in any truck the year of his TB or newer then it is illegal. True, BB power is tough to beat but it sucks to own a vehicle that you can only trailer to car shows or dragstrips. I know your love for the BB, I want one for my 93 OBS truck, buy me a Musi/Edelbrock 555 with fuel injection and I'll put it in my truck and you can come down and drive it any time you like.

Maybe the states that used to allow older motors are the states that don't have emissions inspections at all now? Possibly the rule you mentioned always applied and I didn't know, because I've never had a fast car that wasn't available with a big block from the factory at some point. I don't know where the OP is from, but maybe he lives in a state that doesn't check for emissions.
But yes, it would suck to make the truck not legal for the street because of the motor.
A 555 would be nice. The way things are now it costs about the same to build any size BBC up to somewhere around a 572. All the parts are off the shelf parts and the prices are about the same for many different displacements.
