300, 350 or 385 GM crate motor?

I'm going to be replacing the old worn-out, weak-in-the-knees 250 in my '69 this summer and I'm trying to decide which motor to get. I've done a bunch of research and it looks to me as though one of the best routes to take would be a GM crate motor in lieu of building one from scratch.

I bought the car 22 years ago, garaged it for the last 20, and now it's time to give her the horsepower she deserves, but I am also older and wiser. I'd like to make the car comfortable to drive, this makes me lean more towards the 330, but then the 18 year old hot-rodder at heart wants to shoot the moon and get the 385.

So let me hear everyone's opinions regarding which motor to use.

Thanks,

Steve

Re: 300, 350 or 385 GM crate motor?

whats your realistic budget, and do you have the skill and tools and inclination to assemble an engine if you got one as a large pile of quality parts, if it would result in a better engine?

are these engines an option

I happy to say that after 20 years, a college degree, and being smart with my money, budget is not a concern. I also grew up a farm-kid so I've been around engines my whole life.

Thanks for the info on the other motors too. I'll look into them.

You answered yer own question Steve....
Go with a 383 that's got some poop behind it. It'll fit just as well as any of the other small blocks and mount to all the same transmissions.
And you can pull tree stumps if ya ever need to.

My dad had a Fastburn 385. The motor is super streetable and has a mellow idle. The extra power is made in the aluminum fastburn heads/hyd roller cam. I would go that route for sure over the 330 if you have the extra cash.

Friend, if you settle for the 330, every time you punch that throttle you'll be unhappy. Buy the horsepower so every time you punch it, you smile...

Re: 300, 350 or 385 GM crate motor?

Thanks for all the responses.

I just have this feeling that the 385 would be too lopy, and I really want an engine that runs well for my 12 mile morning commute and won't be too much like sitting behind a jet engine. Don't get me wrong, the extra power would be a kick, I just want this car to be very drivable.

It sounds like the 385 would be a good choice though.

The 385 is not lopey or radical. Nice engine & the price is right. Another nice GM option, the ZZ383 (425 HP and mild mannered)

Have fun.

Re: 300, 350 or 385 GM crate motor?

I know this may open a whole new can of worms, but from what I keep hearing about the DZ302 (290 hp) motors in the Z's, they ran like raped-apes. Now I know they were under rated, but compare 290hp to 350 or 385, and it seems to like the 350 would be more than enough and the 385 would just be over kill for a street application.

I guess the new engine technology allows for higher horse power motors that don't fit into the old lopey, WFO motors of the 60's and 70's, but can someone explain to me what part of this equation I am missing?

Correct me if I'm wrong but the old SS Camaro's ran 275 or 300 most of the time didn't they?

I think the older, and more cautious parent is getting into the discussion now. Forgive me.
