idk if anyone here knows this im going to search elsewhere on other forums

does anyone know what they called the 350 back in 84

It should be the TPI 350.

Crappy Hp from the factory, but it least it had a good base to start off with IMO.

Theres all kinds of aftermarket stuff for those engines so you will have no problem getting a good bit of power out of it.

Good luck hunting!

Ugh, the 84 was the crossfire injection junk. I don't think there is any hope for that one other than to ditch the whole motor and computer and start over. I hope you got it reaaaaallly cheap. :D Could have potential though.

its decent in speed

but for a corvette its not very fast

yea dave i thought about ditching all that stuff

more then likely i will one day but its the new d.d for now since it gets about 10mpg better then my truck haha

Time for a crate motor.... A stock vtech accord would rape that thing.. Freind of mine had one and it was aweful.. They run like 11's/12's in the 1/8th mile (if they run right) get a good 4-bolt main block and build a 383 stroker or just buy a crate motor.. all chevy v8's and transmissions are compatible with each other.

BTW incase you didnt know by buying a vette you have officialy joined the 'small *****' club ! hehe

sorry i couldnt help myself.

id love to ditch the crossfire

BUT im having difficulty finding proper ways to do so

crate motor yes

but everything runs off electronics so if i did carb id have to run a computer to power all the power features it has

im looking into swapping a lt1 manifold and setup onto it

ditching crossfire

Step one

Pull it off

STep two get a carb and intake

Step three do fuel system...Yahhhhhh Or just drive it as is

Id look for a real short guy driving a Chevy diesel truck and see if he wants to buy it.....Might be able to double your money...

1984 Corvette

I know a guy that has one he bought some new Dart aluminum heads and Team G intake picked up a bunch from stock. He also installed headers and Borla exhaust

Dont mess around with half baked motors. This one comes in two flavers
ZZ572/620 or ZZ572/720R deluxe. Were talking big block here. The last nubers are the HP:D

Just go to www.gmperformanceparts.com
for ten grand you can shut down almost anything on the street.

Flip it and use the money to fix the bird. That thing is going to eat you alive. You will pay a premium for everything, also known as the Corvette tax. I will predict the cross fire problems along with overheating issues. Seats on foam for my 91 C4 is 1K for 2 seats but I can outfit the entire SC for 600 hundred. A single door panel is 400 dollars.

what temp does your vette usually run at this one seems to like 186 degrees or so at a cruise

it goes down to 178 or so at a idle

as for oil pressure i see 48psi at idle and about 62-65 at a 45-50 mph cruise

oil temp seems a bit high need to check the sensor its running about 205 degrees oil temp

CEL is on at the moment but it does run really good i think it needs a tune up

04-13-2008, 10:24 PM
They typically run warm. The turn on temp for the fans is some ridiculously high number. The after market vendors offer a dif temp sensor for lower turn on. It has been over a year since I drove mine so I do not remember at what temps it was running. Does your CEL come on when you get up to highway speeds? Mine has a bad EGR flagging the CEL but it does not cause on driveability issues. My old 91 Formula had the same EGR issue causing the CEL.

I tore ours down to change the red interior to black but have had other things come up around the house.

Should have bought a mustang gt...

Cheaper to buy
Cheaper to build
Faster To begin with
Better Gas milage
Ford product
Doesent make everyone think you have a small *****

04-14-2008, 04:22 PM
Cheapest thing to do would be get a carb and intake. If you are using it as a daily driver, then the better thing to do would be a TPI350. You can pick these up pretty cheap, and while they aren't the best for power, they are a substantial improvement over the crossfire. Also, I believe the heads they used on the crossfire motors are complete garbage, and considering how cheap small block chevy heads are, a set of aluminum heads would help you out a lot.

im not a fan of mudstains

anyway the insurance for this thing is dirt cheap $350 for 6 months for me and im 20 years old

every mustang ive looked at is 1200+ for 6 months insurance

ill take the vette hands down everytime and build my sc up
