Ramjet Manifold

[Iceslim0]

I was looking at prebuilt blocks ( I decided against the rebuild ) and I saw the GM 350 Ramjet and I had a few questions, and they are probably stupid ones.

Does the ramjet have any relation to the throttle body?

Is the ramjet taking place of the intake manifold or is it just sitting on top of it?

Could you supercharge something with a ramjet? (I wasn't sure if a supercharger replaces the intake manifold because I've seen ones that bolt onto the side)

That's a 1st gen small block. It won't work in your LT1. No OPTI and a few other things.

[Iceslim0]

Yeah I just realized that. All the engines that I was looking at were pre-1976.

I'm having real trouble finding a good crate for around 5000

Dude, why do you need a crate motor? Just rebuild your current one. Its a lot cheaper and you can get a lot more power out of it.

[Iceslim0]

Because if I rebuild my current motor with those parts that I told you about, it was going to run me 5200$. I already picked out a long block. It's a 383/440 for 5600$.

[Z Ya Later]

No offense, but those parts you listed weren't that great. Have you looked at the cost for a head/cam package? Stroker kit? Freshening up the block? You will spend way more money doing a motor swap than you will doing a rebuild.

[Iceslim0]

Well a 383 stroker kit runs about 1500$ right? I would have to rebuild the whole thing if I wanted to have it blown. That would cost me somewhere around 4000$. I might as well just drop the 7000 and get a whole new engine and everything it needs to get it running.

With that 383/440 block, I probably wouldn't even need to supercharge it.
If I rebuilt with a stroker and put a blower, it'd still run me somewhere around 6 or 7k. And at least with the new block, it'd still be an option to supercharge it later if I really want some heavy horses.

Not sure if that made sense, it did to me.

What makes you think you need to supercharge the motor to get good power out of it? Read...

Even the base package will give you about 445-475 hp depending on your cam choice, and that's only $1600 for some work on your heads and a new cam. Then add the $1600 for the stroker kit, another $425 for some intake work, $725 for a new valvetrain kit and another $800 or so to have the block freshened up and you're sitting at $5150. It'll be all naturally aspirated and you'll be making more power than that 383 long block you're looking at. Do more research, a motor swap is not the first option you should be thinking about.

[Iceslim0]

You are an effing genious. How much work is it to totally take apart the block and get it 'freshened up' and what exactly do you mean by that? How many hours of labor would it cost me to have all that stuff done versus the labor of dropping in a crate?

Say if I went with that maximum package, and did all the stuff you suggested, how many horses do you think I could pull out of it? And what if I did other things like headers and ignition and anything else.

You're not really going to pick up anything on the ignition. As for hp ratings, talk with Advanced Induction.

Getting the block "freshened up" is basically having a machine shop go over the block, check the bores (usually they'll bore it .030 over), re-hone the block (if that's the proper term), check the deck, etc. You'd have to take the motor out of the car and completely apart. But, if you go with a head/cam package, you'll be over half way done with this.

Labor cost would vary depending on the area, rate, etc. I have no idea what rates are outside of my area, so I don't know. But, there's no reason to take it to a shop. For the cost of the labor, you can buy the tools and do everything yourself.

[Iceslim0]

Well I get all labor done for 40$ an hour and I will get any machining I need done for free because a good friend of mine's dad is the manager of a machine shop and owes me several favors.

Aside from the block work, can I get pretty much all that stuff from advanced induction? Do they sell a stroker kit? If not where could I get one for under 2k?

If I get the 200cc package, what valvetrain would you reccomend? Is there anything else you think I should grab too?

All Advanced Induction does is head work and sell valvetrain packages. For stroker kits, look at Summit.

As for the cam choice, as I've said already, talk with Advanced Induction.

[Iceslim0]

But they sell the had packages and deliver them right? I don't have to send them my block do I?

Summit sucks for stroker kits. I found some here:

I'm guessing I want forged. There's a lot of options, wasn't sure what to go with.

Since I'm aiming for 1000hp, I'm guessing I need something with the Oliver Billet Rod 5.7-6.125 1000hp 7500rpm. I was thinking the part number SKC38327 the base price is 2669$.

[Z Ya Later]

I've pointed you in all the right directions. Its up to you to do your own footwork. If you want to overspend on your stroker kit or do a motor swap, by all means. You will be throwing away your money. I've done what I can, I'm done here.

Dude, if you want 1000 hp, you have to build your entire car. And that's going to cost you a crapload more than $5000.
