ive got a 350 tpi that runs and now ive got a 305 carbed nonrunning i was told i could take the 305 carb set up and drop it on the 350 right ? so do i tae the whole thing intake and maifold or what ? and i want somthing a little better than stock since im going to be building up ithe 350 while its out of the car like cam header and such .. so i would like to know what kinda intake i shoul dbe looking for and it the stock 305 manifold taht im going to put on the 350 is going to support it ok .. i would appraeteate the help thanks .

If I'm not mistaken, the 305 and the 350 are identical with the exception of the pistons, cylinders, and heads. So with that said, anything attached on the outside of the engine like the intake manifold and carburetors should fit just fine. I checked out the Edelbrock part numbers through Summit and they are the same for the 305 and 350 manifolds.

Good luck!

The stock carb manifold will support a fair amount of power but may run out of breath at higher rpms. Depending on your choice of heads, hedders, cam, stall, etc. you may want to upgrade to a better flowing model. If the carb you're swapping is a ccc-qjet you'll need the ecm/computer to help run it.

But if the stock manifold is cast I'd lose it for weight and heat reasons.

Guro 305

Edelbrock's manifolds are aluminum. They weigh like a third what the stock steel ones weigh. If keeping a q-jet carb, go with the dual plane manifolds. Not only do you not need the single plane, but the single plane isn't designed for the stock hood of an F-body without cutting a hole into it.

Most of what you say there isn't true. 3rd gen "stock" carb manifolds are aluminum, except LG4's delivered in Canada. Single plane manifold heights vary, so don't paint with too broad of a brush - there are some that are lower than any dual plane intake.

Guro 305

Actually what I said is all true......in regards to Edelbrock. Just ask Edelbrock. I did, that's the info I'm relaying here unless Edelbrock is full of crap.

I specified Edelbrock manifolds, not any other manufacturers so make sure when you paint with your brush, stay within the lines! I'm sure there are other manufacturers that do make single plane manifolds that are a lower height then the dual planes. But again, if he's gonna use a stock carb, what is the use for a single plane manifold???

what's wrong with the TPI on the 350 currently?

An aluminum Edelbrock manifold will weigh the same as an stock aluminum manifold. I'm not implying that Edelbrock is "full of crap", but they are not accurate if they are saying their manifolds weigh a third of what any stock manifold weighs.

Stock carbs are maligned all too often, again with that broad brush. However, the originator didn't say anything about using a stock carb.

If you go to the Edelbrock website, you'll find they list the height of their manifolds. The Performer spreadbore dualplane is 3.50"-4.60" high (front-back), Performer EPS squarebore dualplane is 3.74"-4.80" high, and Torqer II singleplane 3.53"-4.63" high.

Your point being? Still, you wouldn't need a single plane manifold unless you were using a double pumper. From what Edelbrock told me, the manifolds you would use would be the performer series or the victor jr, the performer series being the dual plane that would fit a 305/350 and keep the stock hood, the victor jr. being a single plane that would require hood modification.

Note the originators post carefully. He asked if you could drop a 305 carb setup on a 350? Since he did not specify anything being aftermarket, one must assume he is talking about stock parts. The weight of the manifold is compared to a cast one to aluminum.

What?
performer is like a stock replacement. That's a waste of time.

Perfomer RPM is what you'd use. $120 on summit, well spent.

Single planes like the victor series are for high RPM race, nothing we'd be discussing in this thread.

*The 350 TPI setup might be worth using*....

I think you guys have scared formulafastfoot away, and I think we can agree that there are many excellent manifold choices, some that require hood modifications and some that don't. The only reason (I can see) not to use the TPI setup would be to get cheap fast gains from mods (head, cam, etc.) without the prom burning. I'd still save it for later.

Guro 305

Sonix, yes, thanks for specifying. It is the Performer RPM that would be used. There is two, the Perfomer EGR and the RPM. Naf, I think you are right, Formulafastfoot ran off.

Maybe we gave him too much info and you are right, I can only see benefits from the TPI. Unless you don't know what you are doing and then that's a whole 'nother thread!!! But T/A Creations sells an entire TPI conversion kit with full instructions trying to make it as idiot proof as possible.

Fastfoot has been PM'ing me about this project. He's got an Edelbrock carb on the 305, it was already installed when he got the car. Swapping the TPI into that car is probably beyond his current skill/confidence level. This discussion really is TMI for him, but occasionally people use the function, so I'd prefer not leaving potentially misleading information go without response. If what you are saying is limited to specific parts, don't use general terms to say it.

Another PM that the project direction has changed, requesting closure of this thread.
