327/350 head and intake questions
 

I have a freshly done 350 block, and I wanted to know if I can run 327 heads(491,492s,etc.) with a smaller combustion chamber.the main reason is edelbrock has the ram log 6x1 intake and says it only is for 283-327. So I thought maybe I can run 327 heads and use that intake but on my 350 block, anybody have any experience on this subject or can explain why that 6 carb intake won't work on regular 350 heads I'd appreciate it

Re: 327/350 head and intake questions
 

should be the same , the heads will interchange ,and the only reason the old intake would not fit is if you have newer than 96 "vortec" heads

That's what I thought, but I did t know if I put 327 heads on it and block some water passages or something, it is a 1970 350 block, and I'm going to try to find 327 heads to bump up the compression and maybe this 6 carb intake, it's going in a 1962 biscayne so it's going to look old school

They are not talking about the heads when they say 283 327 they are talking about the block the 283 327 blocks have a breather in the back of the block and no holes in the valve covers the oil is poured in the engine thru the intake in the front , the heads fit from 1955 to whenever they stopped mmaking smmmall block chevy engines but as mentioned above the vortec heads are different ,,

So I can use the intake on a 350 but there is a hole in the intake for the oil fill. Is there something they make to block that off where I can fill it through the valve cover like a normal small block, or do I jut have to give up on on having a 6x1 intake on a 350

Yes you can use it on a 350.
No it doesn't have a hole for an oil fill tube.
Just a thermostat hole and a distributor hole plus heater hose hole.

You can block off the hole with a freeze plug and use it with any pre 1987 heads you like

Re: 327/350 head and intake questions
 

If an intake has the oil filler hole you can block it off the one pictured does not , also edelbrock advertises items to fit the 283 & 327 because those engines are pre smog ,,, they know you are gonna use them on engines newer but they cant say that ,,,
