I am building a supercharged 454. Forged crank, forged rods, forged 2399 Pistons. I am using rectangle port heads with 2.25/1.88 valves. The blower and carb is stock 525sc stuff. Per mild thunders recommendation, I told my builder I wanted a crane 134561 cam. I show up, pay for it. He then hands me a comp 11-314-4 cam card. I said this is not the cam I speced. He says ya get what I give ya. It is half way between the stock 525sc cam and the cam I requested. He is telling me it should make 610hp. What do you guys think?

I wouldn't use the comp cam,not enough degrees on the split,,should shoot for 8-10 degrees and not liking the 106icl or 110ls.I'd be looking for a used hp500efi cam,but thats me.

He builds a lot of marine engines, but it's not what I wanted and I wanted a bit bigger. I am just unhappy with quite a few things with the builder.

It is supercharged so it will be fine . I agree with stupen though especially if it was normally aspirated as the crane would be better with later closing .
You would have thought you'd get at least a phone call.. Ego engines inc??

He added $1000 to my bill with only one call to add a cam. And the cam was specifically 134561. He also said he would match summits prices. Everything was marked up.

Disapointing .. But it will be a good combo and the bill will be long forgotten when your hearing it run..
Is this a freshen? Upgrade? Before and after post will be good

Regardless if the cam he gave you will work or not, you're the customer and if he just arbitrarily changed cams on you with no discussion then I'd have a big problem with that.

It is a long block freshen with the addition of a supercharger. i have a very disorganized thread going already. I am having the motor dyno tuned at the builders shop. I know for a fact, the cam I picked makes 590hp in my setup. I am gonna give his recommendation a try. But if it falls short I am gonna be disappointed.

That was my feeling. Right or wrong, it's what I requested. Another things is I had my head guy build my heads with springs to fit the cam I specified.

He probably had the comp cam laying around already spent your money on something else and you get what you get...
