454 or not?

[Sparky dave]

Scored a running 454.445 block 045 penut port heads. What do you guys think? Pull the stock 350. I have the power bug and thought this was the cheaper and better way to go. The truck is a toy with the bonus of hauling the odd couch or bed. Think i just need a nudge to get it done.

I have a 454 in my 3/4 ton Burb with peanut ports. I really like it, but if I was going to go through the effort of transplanting it I would at the very least put a cam in it.

If you can score some large ovals versus your small ovals you would have a very nice, bullet proof engine for every day cruising and hauling. Gas mileage is bad obviously but I don't drive my toy vehicles enough to care about that.

Given that they are equally in good running condition...stock 350 to a stockish 454 in a toy cruiser...hands down, here's your nudge!

Don't forget the side effects, however. Springs, radiator, bracketry, and transmission.

I'd probably go to the 454, but if you are going that route, why not do some easy mods, headers, intake, and just a few things to wake it up a bit and not much cost adder. I just did this on a 402 that was stock to the truck, added headers, alum. edelbrock intake, but kept the stock quadrajet. I also added some engine chrome. Running but not road worthy yet, so interested to see how it acts.

045 are regular oval port heads, 236 are the peanut port heads

No replacement for displacement

Thanks guys just what I thought. Going to paint it up this aft. And a pic just for viewing pleasure. It's a v671 blower. From what if found out that don't make a manifold for it and it's 20% smaller than a regular 671 so unfortunately I don't think I'm going to use it. I might open a beer and dream though!

I am using the stock 6 cylinder springs on my truck and it does not sit any lower than with the 250 that came from the factory. I bought a pair of big block springs before the transplant, but the stock springs work fine, seems to handle ok as well. I do have a sway bar, but that was installed before the swap. Brackets should not be hard to come by unless you are going with a short water pump set up. TH350 will handle a mostly stock 454, but a TH400 would be a better choice.

Have the stock smallblock front springs needs lowering an inch so hopefully will air just right with the 454. Also added 100hp to the rv engine by painting it red today!

Yep! She looks faster already!
