I think 345 is achievable with that cam, but to say AT LEAST 345 without any numbers to support it is a stretch. If the car isn't capable of 360 RWHP, you can grow a beard near it and dump a ton of ice on top and it still won't do it.

 

NO way! I thought if you used enough ice and waited long enough that you could achieve any number you wanted

 

my point was that it's possible.

 

I was just kidding man.
I think that cam is capable of 350+ RWHP or maybe a little more, but it takes a perfect running car and setup to get that, which is why I always tend to give advice a little on the low side so that people aren't disappointed in case they don't get what they expected based on that advice.

For example I pulled 348 RWHP out of my 233/239 in an automatic car. That will probably be 360 or just a tad more in a 6 speed. BUT, I invested in quality parts I KNEW would work well together and did the install myself to ensure everything was perfect. Most people save here and there so obviously not everyone is going to get numbers that high.

BTW, hotcams in 350s are through a cutout and usually a ton of boltons.

 

Lots of lift on stock heads is pointless. I think 350 is the highest to hope for. Lots of people with bigger cams on stock heads don't even make 360rwhp.

 

Probably because the LT1 heads can only handle so much lift. Anything above a certain lift won't give you any more hp/tq. Many have decided that the 227/233 or maybe the 230/236 would be the biggest you'd want to go if you retained stock castings. Of course there are a bunch of people with 233/239's and 847's that have laid down some unbelievable #'s with stock castings, but most people draw the line at 224/230 or 227/233.

I'm aware of this fact as i posted it in the first line of my post. Anything really over .500 you are just pissing into the wind on stock heads.

 

Actually Dave has heard many people dynoing 340-350rwhp with this cam and lt's and some even in the 360 range and someone who hit 380 but heard he was a liar so he took it as a possibility. This cam goes excellent with the stock heads... thats why it makes good numbers.

They sell a bigger cam 230/236 but it makes less power. Bigger is not always better with cams... at least thats what i'm told

 

I guess what i'm wondering is why did you make this post if you have already been told what it should put down? Its not so cut and dry as you make it. People with the GM847 make tremedous power and the cam specs are 232/242 if i remember right. Thats obviously bigger than the 230/236 and it makes more power than your 227/233. I do know that bigger isn't always better but for you to come in and say that the 230/236 or bigger cams will make less power than the 227/233 is .

 

340's on a dynojet with a tune, maybe high 340's.

 

I still think you could pull over 350 with a dynotune on a manual...and of course all other bolt ons...

 

Actually, the 227/233 wasn't in stock but the next size up and The bigger one cost more, but he told me i'd get more power out of the 227/233. So he easily could of sold the bigger cam but he said i'd like the 227/233 more and i'd get more power of it because of wider power band.

 

Great choice...

 

well i'm new to the board so hello all.after much thought and research and wanting to have a great street cam and still put down good numbers i chose the 227/233 cam.a local shop has this cam dynoed at a tad over 380 with a auto.lt,ported heads bolt ons and dyno tuned.my set up is mid length asm headers 3" cat back borla ,ported heads,52mmtb,and bolt on's.i will see at least 360rwhp...and be happy on the street.good luck with your set up and GOD BLESS.

 

Going to head over to the dyno this weekend... anyone want to take anymore guestimations? Mods are in sig
