Hi are any of you guys running the xe285hl cam? Just wondering what it will sound and run like ?
What are you thinking about putting it in?Hi are any of you guys running the xe285hl cam? Just wondering what it will sound and run like ?
Sorry Brian, That grind can be for a small block or a big block. Jokes on you!You guys need to learn to use the internet! one quick search about 30 seconds and I found this.

You put that in a 273 and it will sound like a top fueler. Put it in a 408 and you wish you had one bigger.
It sounds like this at 800rpm in a 410" with 1-5/8" headers, Flowmaster 40's and 2-1/2" exhaust.
And this at about 4500rpm...
(excuse the poor quality audio and wind noise on my phone.)
0 deck .039 gasket is 10.75I agree Iam just a little concerned about my compression I think it is going to come out at 11.2 so just looking for a little more cylinder bleed off if I'm thinking right my 360 block is zero decked with kb107and 63cc heads really want to get it right the first time any input on this would be great. I have also been thinking about stroking it and getting different pistons and lower the compression some options for both ways would be appreciated
Thankyou for that0 deck .039 gasket is 10.75
high 60 low 70 degree intake closing will run great on pump gas. 240ish @ .050 intake duration
Yep, I agree; I get SCR = 10.65, with the same head gasket. DCR end sup around 8.2 for that cam at an ICL of 106. Should be runnable on pump premium; take care in tuning.0 deck .039 gasket is 10.75

'Run good' is somewhat hard to target..... Run good on the drag strip and run good around corners are 2 different things. I was thinking a 274 or 278 might be better IF you are doing a lot of powering out of corners on back roads. But, I keep forgetting that 3.91 gear....I was going to go with the xe274 at first and one machine shop said the xe285 would be a better choice. I really want this thing to run good
I'm going to go roller rockers and solid lifters I was going to stick with 1:5 ratio and run a 2500 rpm converter I also have a 670 Holley vacuum secondary's and I have been reading about the efi systems. Maybe that's the way to go idkI would not use 750 double pumper on the street if I had to buy the gas
that 285 is a big cam for a 360 so it needs the compression you are going for but also gears and converter depending on how and where you are going to drive it you have 3.91 so you should be ok for hot rod use ?converter?
IDK about a drive to work daily driver.. it's going to be soft getting going even with the gears
If you need crank work and rod work and pistons then a stroker makes sense more torque more driveability
top end power is in the heads so no change there- and top end power is overated for a street build- you don't get there very often
what rockers? if roller tip price in a B3 kit and then 274 with 1.6 makes sense or go solid lifters like thousands of 273's- works fine

It is a street avenger I also have a edelbrock can't remember what cfm it is I think it is a 750. I don't really like them as well as a HolleyWhich 670 Holley do you have? If it's a street avenger, I'd keep it on the shelf. I tried one on my 340 and it ran like crap. For engines with a bit of camshaft, the idle circuits are way too lean on those carbs. You'll have to open up the idle feed restrictors to keep it from bogging down. The 750dp will be a better carb for the motor IMO.
