Is that worth the extra bucks ??

The vortech's are great for 327's IMHO. What kind of 350 head are you considering ? Make sure the chamber is small, around the 64 cc's like the double humps had and the intake runners are small, like around 180cc's etc.

Unhappy

No, they have a different bolt pattern. You can buy a different manifold and valve covers or get heads that are drilled and tapped for the old style. (more money). Another possibility is to buy diffent heads like the RPM's, world, Dart, etc.

Please read what I posted under the 327/210 post above and hopefully it will be of some help.

As for a lo-po 327 motor, the CR. is so low that you just can't slap a good sized cam her AND get her to run good..

My .040" over 327 with about 9.75 to 10 to 1 CR. and with medium valved double humpers ran great with no more then a Little Fireball type cam in her so this should tell you something!!

Please look into the 305HO, -416 heads b/c they just may be the ticket for you and a 327 hi-po motor runs really great with no bigger then the stock, -461x big valved headed variety with ports right at 170cc's..

The usual heads on alot of the hi-po motors were like just medium valved sized double humpers at 160cc's or so..

And don't forget to install a cheap set of headers b/c the little motor likes to breath good on the way out, too!!

Just my humble opinion and really only trying to help.. pdq67

PS., and sure you can get them to run real good with a 290/250 or so solid cam BUT you have to have at least 11 to 1 CR. or she just won't work.

My long gone crippled buddy that had the '58 Vette Convert. with a '64 375hp/327 F.I. motor in her and an Isky Z-30 cam would run above 7,000 and still be pulling!!!

Like talk about 160+ with 3.08 gears one night between 10 and 11 PM for about 8 miles or so back when I was about 17 years old!! When I asked what we were running, the tach said 7,200rpm and she was still climbing...

Sh-t, kma and we were back to the hometown!!!!!!

I too am interested in learning more about running 305HO heads on a 327.

They wouldn't be my first choice, but maybe a good alternative if I don't get the GMPP Vortecs to work out due to the special intake man. bolt pattern of the Vortec and my stock A/C setup.

Are the stock 305HO Intake ports about 160cc's ?

My only concern with the 305HO heads is the 58cc chambers boosting my compression to over 10:1 (bad news for running on pump gas)

Well....maybe running the thickest head gaskets you can buy might help some... [img]smile.gif[/img]

I think 10:1 comp. ratio works well,where i live the pump gas is 98 octane.
Is the octane much lower on pump gas in the states?
What years did the 305 HO come ? And can i use all of them??

Thanks for all Help.

Ok

I looked at the sdpc2000 site.
Seem to me that the vortech heads kits are great,to an afordable price.
Would the SD8060ARPM kit work on my 327/210?,or it there other kits you would recomend?


ok

I think the European octane rating is derived using a different method (research) from American octane rating (research + motor /2). This would make the same gas get a higher number in Europe.
