What do you have for heads?

If they're stock them in going to say you are right around ~300hp. Your cam and intake do not quite match. You need to either go with a cam with its powerband in the higher revs or an intake that's efficient lower. It won't show as much at the track, but on the street it will be doggish on the low end. A nice dual plane like the Performer RPM would be your best option for that setup.

If you want 400hp you're going to need some good heads and a bigger cam.

You didn't say what year so I'll guess you're around 8-8.5 to 1 compression. With the low compression and probably 76 cc smog heads the combination you are quoting just isn't going to work. Yes, it will run, but not very good.

My opinion....the double pumper is a no-no for the street, just a semi-controlled leak. The Torker ll or any single plane is not optimum for the street, they are high rpm intakes and with your heads and compression it would probably be all wheezed out at 5500. Again, with the stock engine that cam, though not radical is too much. With your stock engine and the right combination of parts that you want to change you may see 325 hp. @ the flywheel.

they got a good point I would run a 600cfm holley vacuum secondary,cyclone/performer intake,and keep that cam,you could probably upgrade to vortecs and do really good you would be suprised how much better it will feel afterwards trust me

[curtis73]

Performer RPM will be t!ts with that cam... but the others are right. How about casting numbers on those heads.

333882 just stock 70 ccs

I think you mean 76cc's stock. I believe that is where they were from the factory they may be as low 72cc but that is about it. Make sure you check them for cracks. I just had a set that a guy took off a running driving motor and took them to get them checked and they had 3 cracks in one head and 2 in the other. Between the valves was the biggest problem. You owe it to yourself to get a better set of heads. Something with smaller combustion chambers and better flow.

[KNanthrup]

Yeah 882's are going to clog things up. I doubt you will see anywhere near 400hp with those. What kind of budget are you working with? I'm sure we could give you some suggestions to meet your goal.

I have a 350 with a high end cam and manifold and headers and a 700 cfm carb

I was wondering wat would be the best parts from here to get 400 ponies plus
Without a cheater kit

And I have a double roller chain with a advance and retard key if i advanced or retarded it which way would i get the most power out of it.

Specifically, what cam, heads, pistons, compression.

400 horses from a 350 is not too difficult with some right parts.

get some 190cc aftermarket heads and a AirGap intake- that alone should put you close with your combo. put compression at about 9.5:1 and the cam duration at about 235/240 @.050"

[Double_v23]

Adding this part will definately get you 400+ ponies

That wouldn't be a good HP/$$ value for 400HP, plus you'd have to change the cam and pistons to blower specific type stuff - not to mention crank/rods.


Like oldbogie said, it's not hard.

What's your 'budget'?

What do you have now, specifically, all of it?

[Double_v23]

No ****, I was being sarcastic. He could just bolt it on as is, it would make way more than 400 horse for at least 10-15 seconds. On 125 octane fuel.

[chevy350_Camd]

I was thinking of a 383 and couyld u give me some advice for 400 + for 2000

Like any parts that would give me aloty other than a blower lol and nos
