i was wondering what intake manifold cam and carb would give me the most power on a small block chevy thanks alot dustin

The 350 was made for many of years. Give us an idea of what your starting with.

Whatever you buy check out ebay. There are some nice deals to be had on sbc parts.

If it is a stock non emmissions 350 You can get a little more power by switching to about a 252H cam, a nice dual plane aluminum intake and about a 500-600 cfm vac sec carborator. However in my honest opinion I would save a litle more $ for a nice set of heads,and about a 270h cam (depending on the heads) You will be able to tell a big difference with a head/cam change but if you are just on a budget that will not allow for a $1000 set of heads then yes a cam/intake/carb would be your best bet.

this is my opinion

we had a s10, with a nice low budget 350 in it that ran 12.70;s..it had stock type pistons(4 valve reielves) a 650 holley, rpm intake..and a comp 280dur with .480 lift and bone stock heads(other than valve springs)..we got the kit from notheren auto parts..kit cost $150.00..cam -lifter spring kit was around $300.00..intake was used from ebay..100.00..it ideled nice, and ran hard..for cheap..

the engine has power pack heads i am not sure what year it came out of the numbers on the block are 3970010 there is no smog crap on it. can you tell me what combonation of intake, cam, and carb would give me the most power
please be specific thanks for your posts -- dustin

3970010 is a good block from years 69' to 80' mostly found in Hi Performance cars and trucks. They are 2 or 4 bolt mains, 4 bolt if you're lucky. In the general area of where you found the casting number is a date code that will start with a letter followed by a couple numbers.

I would recommend keeping the cam relatively small because the heads are not designed to work at a really high RPM. I would assume they will be able to support no more than 5000-5500 RPM on a 350. This being the case, you want a cam and intake that will perform well here also. I would recommend the XE262H ( 218 224 @.050 .462 .469 lift) cam for your motor along with a performer RPM intake and a 600 CFM carb. This combo with a 2000 stall should make good power for a street car.

Look at combo number 18. I would assume that your heads are comparable to these. A cam with .230 @.050 duration should make power to around 5500-6000 RPM assuming the heads will allow it. In this case, the max power was made at 5200 RPM. I think this is a little too much cam for these heads. I think it would be more beneficial to go with one with a little less duration, to focus on the lower end power. The performr RPM may seem a like a little much, but I have not been impressed with the performer from what other people have had to say about it. Also, the performer RPM starts making power at 1500 RPM, with a 2000 stall, everything will be making good power when the stall kicks in.

What rear gear you have?

[dustinweaver]

i have 3;33 gears

[dustinweaver]

can anyone also tell me how much hp a stock 350 with power pack heads has --- just a guess??

[dingerdq]

Just a quick note to your question.If you go to your Chevy dealer and buy a set of Vortec heads (400.00) new.They will add 30 to 40hp bolt on. I would recomend a280/480cam, 750 Holly on a dual plane manifold that made for the vortec heads. This is a tried and true combo that you will injoy,and not cost you an arm and leg.

[ap72]

the heads are not that cheap and they require a new intake manifold. However I do agree that they are a good investment.

[dingerdq]

if you want an engine that will perform well and stay together for street use, with some heart cheap is not allways the best answer.I enjoy driving my machine more and working on it less.Sometimes the rework that you need to put in cheap used part cost more than a new one. dingerdq
