I'm freshening up a 1974 low comp 318 with a quick hone, new plasma moly rings and new bearings. I done some home bowl porting & port matched the 675 heads with larger 1.88 / 1.60 valves. SCR will be around 8.5:1 with Mr Gasket 1121G (0.028") head gaskets. Using a port matched Performer intake, 650cfm AVS2 carb, Prestolite dual point distributor, and 1-5/8" Dougs headers. It'll be going into a 67 fastback, 4-speed Barracuda, with an 8-3/4" 3.23 geared rear. I just want it to sound cool, turn the wheels and run nice on the street.

I have a new Crane Cams Z-268-2 flat tappet hydraulic stick that I was thinking of using, has anyone run one of these in a similar combo with good or bad results?

CRANE Z-268-2

Duration @ 0.050 212 / 220
Lift 0.459" / 0.480"

Depends who you ask :) it looks about right to me, think about milling a bit of the heads and or deck to bump cr closer to 9:1 ?

I wouldn't use "plasma Moly rings" with a "quick hone" either. But that's just me. Plain old cast rings for a deal like that.

That’ll have a mostly smooth idle and make OK decent power. I ran a very similar Crane cam in a stock long block ‘79 - 318, 904,w/3.21 gears, hooker headers into a Jegs dual exhaust, LD4B and a 600 Holley. With regular stock sized tires it could get into the high 14’s easy enough. Traction was an issue.

You should be able to pull down 17 mpg’s or slightly better and better than I did in the 1/4.

Okay, thanks rumblefish360, sounds quite positive.

You already have the cam, run it.
It’ll make for a nice easy driver. If you’re looking for that muscle car sound as well as increased torque, look for a cam a 108 LSA.

Take a peak at “Howard’s cams.”

I was talking about the cam.

I literally just stuck one in over the long weekend. I'm at 10-1 318 60 over.

I'll let you know how it goes.

I have a similar 318 build with 8.7-1 compression, 2.02 J heads, and I used the Comp Cams XE268 that has similar specs to yours. I installed it 4 degrees advanced and it has excellent low end performance. Out of steam by 5500 but that’s ok. Just make sure the valve springs are spec’d to the cam, or even a touch stiffer, and she’ll be a ripper.

Any update on how that Crane cam turned out?

No yet, too many "other" things to attend and then there are the "Love Jobs" I have to get done.

Hopefully in the coming weeks I'll be able to get back to you.
