Can't believe I am asking this but, wouldn't that be too much head for that little 350? A 180cc possibly milled to 60-65cc might be a better fit depending on cam and whatever else is bing installed or upgraded.

On a different note, you can remove the cam without removing the AC condensor.

 

Its getting a little "large-ish" and you wouldnt want it for your basic mild hot rod build.
It is useable as long as you have efficient heads and want to make power in a higher rpm range.
For most guys wanting to make 400hp with a 350, in my opinion they would be better off
with a good set of heads in the 180cc range.
If you step up to a 383, the 195 to 200 range would be a better fit.

 

For the past 25 years nearly everybody at the cruise night place has 400+ hp 350 ci chevy because they threw in a cam, headers worth 50 hp and a K&N filter worth another 25 hp. It is really not that easy. If you are not able to spin at least 6500 rpm you are not going to be getting the magical 400+

You don’t understand an intake port if you think 10, 15, 20 cc’s change in port cc volume really makes that much difference. You have to look at the total volume of the intake individual tract. How well the carb and the intake atomize the fuel is much more important .
Just look at the massive port cc volumes used in the modern LS..X motors to be getting 400+ hp out of stock motors with relatively mild cams. Get away from the 30+ year old wise tails told by bubba mechanics.

For the Record I did not encounter streetability problems running 355 ci motors in my Vette till I tried using ported 230 cc dart racing heads.
As for a 383 the smallest I ever used were AFR 210’s

 

Gkull, I had a magazine kept it for a long time but when ratflinger was considering dart heads for his engine build I mailed the magazine to him. With magazines I take them with some grain of salt especially when it comes to testing different brand products against one another you never know when advertising money could be doing the real talking in this corrupt little world we live in, but I kind of believe this article because they were testing the same brand heads against one another.This article tested iron eagle dart heads and it is an older article done before dart came out with the platinum version that they claim flows a little more air, so anyway they had a 355 that was built like most street engines hydraulic cam, around 10.00 compression, high rise dual plane 750 holley it was no solid cammed say 7500 rpm engine that most people today don't seem to want. So they tested all five of darts iron eagle heads on this engine 165,180,200,215,230 they showed the overall average power fiqures tq and hp not just how much upper end power, they were expecting the 180 runner head to win. the 215 runner head won out both more torque and HP forgot now if it was the 230 or 200 came in second, the 165,180 heads were well back in power. Its been about a yr I guess since I sent the magazine to ratflinger at the time believe he was going to build a 396 was considering a 200 runner dart think he ended up buying 195 eliminator AFR. You can talk to someone tell your blue in the face its not the runner size killing tq its the cam.

 

Thats interesting.

This is also amusing when you start talking about debunking old wives tales.

 

Geez...wouldnt it be easier to yank the motor labor wise???
Then while Im at it.....

 

The ford dominator carb Ford was going to beat the chrysler hemi in nascar they contracted holley to build them a new carb for the 69 season despite the charger daytona ford won the championship that yr.

I thought we put this "heads are too big, can't run a single plane or double pumper with mechanical secondaries on the street" bs to rest long ago. But it still keeps coming back, have no idea where this stuff originated but it sure has a hold of some.

To make power you need heads that flow well, period. Bigger heads will flow better. There is no " oh but you'll lose torque" crap. You will actually make more torque than smaller heads because you are simply making more power.

The 355ci I had in my Vette a while back had all the "wrong" parts on it. 200cc heads, 10:1 CR ( it'll detonate ), solid lifter cam, Vic Jr. single plane intake and Holley 750 with mechanical secondaries.

I had a 3.08 rear end and the Vette was a blast to drive, no it didn't bog of the line, it would light the tires up. I put it on a chassis dyno and it made 297RWHP and 336RWT. I wonder how many 350's normally aspirated are making 300RWHP on this forum. Like gkull says nearly everyone with a 350ci at car shows is making 400+ HP no problems

Hmmmm I hope my AFR 227's aren't too big for my new motor
