i just bought a rebuilt 350 from my stepdad (only 400$prettty good deal).030 ova, big cam, comp cam roller rockers, i want to stick with tbi but i need help with which throttle body,injectors,intake that i would need to buy and where to purchase them. Any help is much needed thanx. The engine wont be able to go in to the summer need to save for those much needed parts. For now its in the garage.

anybody

 

If I wanted to stick with TBI and I had a 350 I'd get the first single plane intake on my EFI page, use the stock TBI with 350 injectors. this has been covered a lot lately which is why you probably got no response.

maybe you should do a search, this question is asked a million times a day...

you should use the 65# injectors, you can use the stock TBI unit. you'll want to change manifolds or port yours out... either way... also remember to use a 350 knock sensor and esc module...

burntblues what kind of hp u pushing? at flywheel

 

To tell you the truth, I don't know how much HP I have, I haven't dino'd the car yet, but I figure that it's probably running at about 310 with the setup I have now... I'm going to try putting on some headers and maybe a carb setup this summer, I should be able to squeeze out a lot more that way. I have to see what this is running at first. I just finished breaking in the motor, and you do notice a massive difference between the 305 and 350.

if you need help, Email me,

Burnblues that sounds like the setup I am going to try next month. What cam are you running and how well does it work with the caprice chip? Thanks!

Just so everybody knows, he's got the old double hump heads old school but high performance. The problem is that he doesn't know what grind the cam is and that's my hang up on helping him with the TBI setup. If he has a huge cam and goes with a single plane intake with stock TB and 65 injectors he's going to have a hard time tuning a chip for that setup. It all depends on what cam he's got or is going to use.
If he's got a large grind he'd be better off with a 2" bore TB and at LEAST 65 injectors and will most definatly need a new fuel pump.
I've been trying to help him, we identified the heads which are 64cc 2.02/1.60 valves. I'm going to look into the heads a little more and see what kind of engine builds guys with the same heads are doing.
Does anybody know how to identify a cam? Can an engine shop do it with some simple tools or does it need to be sent out to a cam shop? Please let us know on this post.
Thanks

Is the cam a roller or what? You can tell just by looking at the pushrods and lifters.
You said it's got 1.52 ratio roller rockers so... if they are roller then the lift is going to probably be over .500" and if it isn't it's probably around .470". The duration could be anybody's guess. You said "big cam" so I'm wanting to say between 270 and 280 advertised which is about 225-230. If it's any bigger, you might want to put it on the shelf and get a smaller cam.
You don't really need much duration to make around 400hp. If you find out you've got a nonroller cam (which I suspect from the price you bought the engine for) then a new cam isn't going to cost much $80 new from summit for one of their cams or you could just go with a pulled cam from somebody like Jim Pace. It might be a better idea to get a new/pulled cam just for the fact that you know what it is. Please keep us updated with the details.

yea i realy need to find out what cam is in there ill try to get it figured out within a week

 

DM,

Sorry it took so long to reply. I'm running a hydraulic cam with 280 duration on the intake and 290 on the exhaust actual is 214/224. The cam is pretty mild I guess, so the only problem that I have is sometimes my vacuum is a little low. The cam is mild enough where I don't really have too many problems with the chip, but I do need a custom one. The heads are off of the pickup truck that I got the motor out of. They are like one of the first vortec heads made so they flow quite a bit better than my old ones. Since the chips have no learning or adapting curve, you can't go super wild unless you get a custom chip. The cam is good though because it'll work well when I finally end up carbureting the car.

Chevy Hi-Po or Super chevy had an article on cams a couple issues back, if anyone has that issue you should be able to check in there, it'll probably answer your questions about the cam.

 

Here you go, check this site out... http://www.camtechniques.com/Pages/term.html if your using a micrometer (I think thats it) you can measure all of the cam lobes and that'll tell you about its duration. Lobe spread should be able to be found by measuring the distance between the peak of one (the intake) and the other (exhaust) lobe of the 1 cylinder. (I would guess, right?) If you can find that info from the cam, you can call up a manufacturer and they should even be able to tell you more about it...

Thanks burnblues! That's more cam than I will be running, but it sounds like I will be able to run the GM hot cam that I wanted to in the future once I get setup and learn to burn chips. I will have to pull the heads and machine the valve guides lower because the vortec's that I have only have .515 retainer to seal after shimming and installing .050 offset keys but thats good enough for the stock LT4 I'll be trying first. Thanks for the reminder about changing the knock sensor and the esc module to the 350 versions.

 

why do u have to change the knock sensor

 

That's a good question that I don't know the answer but I know it has to be done. Better to be safe than sorry.

From what I remember the 350 has a different knock signal than a 305 for the sensor to pick up.

 

yeah, the knock sensor on the 350 isn't as sensitive as the 305 sensor. If you don't change them over you will trip your SES light. Its fun to change out the motor and stuff but it isn't any fun when you go to drive it with a tripped out SES light...

does anyone know what car my heads most likely came from there the double hump heads 62cc chambers from a 327 60-63yr car

 

or how much there worth ???

 

They're actually 64cc, I double checked that. And they were on lots of cars. They're worth about $400.
Did you ever get some values for the cam?
