355 almost done
I ordered the cam kit its a comp cam XE 274 cam with matching valve train, I have a friend that is getting a 2200stall converter made and hes converting the trans to early style so I dont need to wire it up, and I oreder a set of RHS 200cc intake 64cc combustion chambers with 2.02in and 1.60ex valves. Sounds like a good setup?
What carb would anyone recomend?

650 Holley double pumper.
You'd be much happier with more stall. At least 2800, 3200 wouldn't be too much. That engine is going to need RPMs right away.
You didn't say anything about intake manifold. Edelbrock Performer RPM.

Re: 355 almost done
Yea sorry I forgot, well I can't get a 2800 if I need it its only costin me 250 bucks plus 100 for the guy to mod the trans, he said ill be fine with a 2400, rpms? Is that cause of the 2.02 valves? They have 180cc intake and 72cc chamber heads I can get but I was shootin for 350hp. 400 he said I would have to change the stator in the trans.

The cam. It won't really get into its powerband until higher than 2200. It'll feel like it's bogging, but it just hasn't gotten into the sweet spot yet. The larger intake ports will contribute to that a little, but not so much as to sacrifice that much compression with the other heads. 2400 would be better than 2200.
My ZZ4 cam, 170cc intake ports, Performer-like intake starts coming on at about 2700 RPMs. My converter, which I originally got for the 305 that preceded the currently-installed 350, was expected to stall about 2000 - it stalled 2300 behind the 305, and 2500 behind the 350. It simply wants more stall, and you've got more cam than I have.
So, even if yours stall more than your builder predicts, I'd still guess it'll be lacking. You might be better off spending more money and getting what you really need.
Haven't asked, but what will you be doing primarily with the car, street driving, drag racing, cruising, combination of these?

Re: 355 almost done
I don't street race, I keep it at the track, I have too much to loose if I got caught (cdl and I drive a school bus). It would mostly be used for cruisin around town and opening it up on the highway if the occasional ***** would come along.
What do you mean save up for what I really want? I can't afford afrs other wise I would in a heartbeat. I spent 1500 on this setup not counting all the work is being done by myself, its a learning curve into something one day I can make a nasty street car out of with the knowledge I learn from doing, iv read a lot online how to do all this and I do have guidence from a freind that's built a few cars himself. Hence why we have a bet his tpi iroc will out run mine.

By combination, I meant driven on the street and raced at the track, or raced at the track and driven on cruise night. I never condone street racing, and never assume it. If people say that's what their purpose is, I will clam up on advice. I've expressed my opinions to the powers that be about having a street racing forum on this otherwise respectable Board, to no avail, so I just stay out of street racing discussions on this Board.
So, sorry, I should have been more clear.
I'm thinking you should save up for a better torque converter. The rest of the combo is fine, but the converter will drag the whole thing down. I'd rather see you spend less on the carb and more on the converter, and I'm pretty relentless when it comes to advising on spending enough to get the right carb. That's where I'm coming from.
Tell us more about this TPI car. Listen to what we're saying here, and we'll have you outrunning him for less money (at the track, of course).

Re: 355 almost done
Lol well I didn't take it like that I was just saying I don't cause of that reason but thankyou for clearing up.
Well the converot is from a guy that makes them for the southern eastern side of pa, the guy that's gonna help me with the trans is a very very respectible builder does nothing but autos for over 30years. And as soon as I brought my cottman built trans and convertor he told me exactly who built it. His normal price is 450 up for a custom built one but since I'm a friend of his nephew he tossed me a good price.
Umm the tpi is the same as mine 86 305 tpi with slp cam, custom chip, shortie headers and 2400 stall fully built trans, bigger 24lbs injectors. That's it, 3.23 rear too.
There is a used carb that's a holley 750 dp vaccum secondaries that I can get used.

Assuming it's vacuum secondaries, a double pumper would be better, but it'll still outrun any TPI engine otherwise built similarly.

Re: 355 almost done
I got the mallory 4309 in the mail today and I have four holes around it and one on the bottom. How do I hook this thing up?
