I would of built a 360. More bang for the same buck.
The guy has a 318, so that's what he wants to build.
I would not be afraid of that 274 cam with your 4:56 gears.
I run the MP 474(which I think is close to the X274) cam in my 340 and like it with 3:55 gears.
Good luck with your build.
If you're running 4.56's, then don't hesitate to run the xe 274....but anything less and a 318, you'd be fine to stick with the 268, especially if you're running eddy heads.

What stall? If it flashes high enough I'd go a step higher cam with a engine like yours, perhaps a XE284H.

Small motor in a pickup which by nature is heavy?
Go for the smaller cam.
Your heads will take care of any breathing issues there are and don't need to be crutched by a big cam.

Normally I agree with you, but if hes making 300hp @ 5250 he's also making 300lbs-ft @ 5250. Remember that \6's ran these things too with realitive ease..

It's a mistake. It is possible to overcam an engine. What size tires are you going to run in back?

28in 295/55/15 MT ET streets!I talked to Ken Hensley,He said i would be happier with XE268 cam and going with 4.10 gear and be much better cruise!So I gonna use the xe268!Now my issue is they asked me about milling my heads,with kb167 pistons and these heads out of box would give 9.7to1 comp but milling them could get 10.1 or could go to 10.5 comp and still run pump.What would you guys do?

Re: XE274 cam - 05/10/12 05:41 PM
The only problem i have is that eventually i gonna take it to track for some test and tune nights at and all we have close is 1/8th mile!Will 4.10 gear be enough!The stall i do have is boss hogg 2200-2800 stall

Re: XE274 cam - 05/23/12 02:37 AM
Well,I am thinking of going solid.Has anybody used comp xs268s cam with 230/236 duration @50 and 488/501 lift?Or should i go step bigger?

If you're unsure of which cam to use, always go with the smaller of the two.

Look at whatever cam catalog you have decided to use. Go clear to the bottom of the list where the biggest and baddest cams live. Look at them, don't buy them. work your way up the list. Its OK to close your eyes and imagine what they would sound like but don't buy them. When you get to the one that looks too small but says it will work in a 318 truck, BUY IT.

/6 engines made these trucks move, sure, but a ten speed bicycle is faster off of the line. 
With the gears, stall, and tires this guy is running my guess is he wants to go fast.
Eddie heads, big valves, small bores, an XE-274, and valve shrouding are, at least to me, a recipe for a really lazy motor. Even if it produces decent numbers up top the usable power curve down low is going to be flat.
All of this aside, you if plan on going big block later on in the life of this project, why blow $1400 on a set of heads you can't reuse on the new motor?

There are some good 318 builders on the site... I'm not one of them but I remember the guideline not to overcam a 318 for best performance. With
230@.050 intake duration, I guess the engine will be lazy until 3500+ RPM. You would need a lot more stall to get decent acceleration. I'm thinking 210 to
220@.050 max. with your setup.
My street driven 318's cam is 263/268 @.050 .656/.662 lift

That's too funny! Also true. Just throw a small RV cam into that 318 and save your money for a big block. Street car no need to go big. Strip car can be peaky but a 318 strip engine will not be what you want on the street. I loved my 318 with just a stock cam and 3.55 gears.

Re: XE274 cam - 05/24/12 06:26 AM
Well,I already had the heads for a previous 360 i had to sell,only had a 318 left,and a sb 727 already built and 8.75 getting ready to go in,so i had to build with what i had.Yeah the 360 wasn,t mild by no means but had alot of torque but had to sell to catch up on some bills.Never even got to hear it run.318 has no torque with what ever cam i run.But i kept brand new eddie heads and airgap intake.Which i figure i stay in XE268 or XS268 cam.This 318 ran pretty good for what it was which was ld340 intake,360 jheads with 1.88/1.60 valve,8.1 comp and stock 340 cam but now it's different animal!With a 2800 stall that already have and 4.56 gears.I miss that little 360 with kb107 pistons,XS274 cam with 502/511 lift and Hbeam rods.Would've had 10.8 comp with 450hp and some torque to go with it but lets see what that 318 gonna do!

Alright,Went to Hensley Performance today and got some good news.Was gonna pay to have my crank done but Ken made deal with me and now have 4.00 inch crank going in.Paid for the crank and block work and He said with my truck,the 318/392 is gonna be better package and it is gonna stay hydraulic and cam is gonna be XE275HL with 231/237@50 and 525/525 lift which will work with my convertor and gonna run 4.10 gear!So now i will have the torque back!So go back in two weeks pay for eagle ibeam rods and the pistons is gonna be KB Icon dished pistons,still have 9.7 comp!

Re: XE274 cam - 05/26/12 11:57 AM
Take Ken's advice.If he says run it then judt do it.I would consider a different converter while you have it apart.Don't know much about Boss Hogg but I would reckon they are cheap and have some slippage.
