That cam calls for 9.5-10.5 compression. and some gear.
But is that because they want their cam to impress you so they do not get a bad rap.
That is the thing about camshafts. They will get blamed for bad performance ..when it could be the rest of the parts.
It is nice if someone ran the EXACT same combo you have and can tell you this is good and this is junk.
That is hard to do really.
My friend at the cam shop told me I change cams like he changes underwear
Yea I like to try things.
But one thing I learned when I was 18 or 19 I need to run ported heads.
That cam in the link is 224@ .050
I have ran 224 at .050 single pattern and it was a little down on power vs my 218@ .050 in a 350".
Made up for it past 4500 rpm and took me from 14.50 to 13.8 et.
But 350" with ported iron heads.
I like to swap cams and see what they do but most people do not.
My 4 door 57 that pulls my boat has 10.87 compression so it runs well with just about any cam I stick into it.
I quit playing with 8.5 compression when I was around 21.
I do want to revisit it but use a turbo in the process.
But even that low compression Turbo trend is not what some of my quick buddies are doing.
10.3 compression and 27 PSI on top of that and running into the 4's in the 1/8 mile!
Friend had stock heads 76cc on his 355" with thick head gasket and non decked block .. ran the 292H with stock springs. valve float at 5600 so he shifted at 5500. It was a turd that sounded awesome.
I raced him and smoked him by 5 bus lengths.
I told him I was shifting at 6900rpm and ran the 270H which was 224 @ .050 on a 110 LSA.
I told him he needs a much smaller cam and he said he did not want to rev it too much past 5500.
I seen him the next month and he installed the 268H which was 218@ .050.
He said it is the fastest engine he had ever built and it had the smallest cam he ever used.
Low compression and NON ported iron heads
Yep!
