Hey im going to start my new project on my 64 Buick Riviera. I already have a chevy 350 and i believe its a 350 tranny. I planned on converting the engine to fuel injection. I saw the ram jet 350 engine and want to set my engine like it. I dont want to buy a whole new crate engine but just work off what i have. Someone said they sale the ram jet kit to convert an engine over, but i cant find the kit, let me know if you know where i can get that from.


Next i want to soup up the engine, thinking about a bigger cam, geared timing chain, performance chip and a straight exhaust. I really want this thing to yell and get tight. Is there anything that i can possibly else to get this thing tourquey and get it yelling up the block. I want it to run hard but not kill my pockets.

I plan on taking out the engine this week and start tearing it apart and hopefully start installing it in my Riv. I also plan on putting the car on bags to thats something not really popular in my area. Also some HID's so i can see the road better, also with a digital dash, and i cant forget about a nice crisp sounding stereo system

If anymore ideas on what i should do just let me know

Not too sure about being able to put the ram jet inection on or what. Edelbrock has a nice EFI kit that is multi port that would be hella nice.

from the sounds of your plans with the project it doesnt seem like your pockets are very shallow, but, as far as cost effectiveness and definite results, have you considered nitrous? obviously need to know more about the motor to really suggest it but just an idea

i might jus have to drive up to jegs its about 1hr away from my house, but i found the edelbrock setup a little cheaper im going to work some numbers and a few things and see what i come up wit.

What is everybody doing now as far as customizing nowadays such as airbags, gills, neons, or etc. whats new on the market thats on the rise for customiztion?

check out Edelbrock;s EFI system........
I am a carb guy myself,so I run heaviliy modded carbs
but EFI is the chit

yea i checked out that edelbrock setup and i found it for a cheaper price than everyone else is asking for. Yea i like the carb but i want a more controlled system with more of an ease of mind.

i would buy an efi kit. make sure you get the whole wiring harness and all the electrical needs because wiring a car for efi is a *****.

Yea i know and it looks like the edelbrock setup comes with everything i need and looks pretty simple and easy to work with hopefully everything is color coded

do you know the compression of your engine? Id bump it to 8.5:1 put a 175-200 shot of nitrous. What are specs for your stock engine as of now? What is budget for your engine build?

as of right now i dont know, the engine is coming out of my dads truck. Isnt there a way to check the compression. Right now of what i plan on doing is already at like 3 grand. I biigger cam, geared timing chain, MSD ignition, hot plugs and wires, and a edelbrock efi setup. but suggestions will be taken i can give and take on what to do. Im not for sure on a budget i dont really want to spend more than 3 grand on the engine but like i said i can give and take on the things i planned on doing ideas are what im looking for.

Bump it UP to 8.5:1??????

That's WAY low for a NA car, and depending on the year of the 350, it could've been designed to run on leaded gas, which had octane ratings closer to 100 than our 87-93... Most of which probably ran close to 12.5-13:1 compression.

What's your main objective by switching to fuel injection? Sounds to me like all of the modifications you're doing are all naturally aspirated, and would benefit from the fueling tweakability of a good carb setup, not to mention there's so many edelbrock carb manifolds for oldschool 350's that add a good deal of horsepower by themselves, and you'd be able to find one that makes peak power in the same powerband as the cam you go with.

What kind of power are you going for? You building a torque-beast, or a high-end horsepower track car?

try www.summitracing.com i find them to be more helpful then jegs. they are up in akron so its not that much farther then jegs man

im looking for some serious torque and the horsepower to back it. Im thinking of range from 375-420 horses would be good for me. i thought about stroking the 350. Fuel injected jus seems a bit easier to work wit, easier starts but ive seen some carberated start right up, i jus havent had my luck with them. Plus wit the fuel injected i can hook up the remote start my dad says its a way to start it wit a carberator but thats in the air. It jus seems to have better cold starts with the fuel injected than carberated.

Awesome, just makin' sure you looked at everything first.

Those edelbrock kits look pretty plug-n-play for the $$. I've seen the multi-port kit on ebay before for ~$600 new, probably just people never finishing their projects.

If you want a good mix of torque/hp i'd suggest a ~270 degree cam kit, any bigger than that and the lowend really takes a hit. With the 270's, you'll still lose a little torue, but has the added benefit of better connection to the pavement from a stop, and from 3000rpms (where a 262/270 comes into it's torque peak) it'll keep bulding torque till redline, so your power increases exponentially as you accelerate, if you know what i mean? The higher you rev, not only do you obviously accelerate, but you accelerate FASTER and FASTER, it's like being blasted through a wormhole in a sci-fi movie or something.

You can go with something bigger, but your torque curve will start feeling really laggy and unnatural, and unless you've got super super short gears, you wont be able to keep it in the power curve, it's pretty easy to keep an engine between 3 and 3.5 grand between shifts, so you stay in the hot-zone.

Just make sure the f/i kit you get is either mappable, so you don't run lean in the highend with the cam, or run a little closer to a 14:1 a/f

Good luck! Those 350's are mean little *****es!

I check from time to time and haven't seen them on there. For that price I would be all over it.

Thanks for the advice homie, so you think i will be in my range of horsepower, with everything im trying to do

I think what he was trying to say is if you run nitrous, it is better to have a lower compression. You would not want to run a setup on 12.5.

get a good bottom end, maybe even a nice forged stroker crank.

go w/ a carbed setup, running bout 11.5:1 comp. Get a 15-200shot plate system w/ a nice rpm single plane manifold. Good cam w/ around 230-240 intake degress @ .050

that **** will ****in FLY
