[308] Cam choice for 355

[Cava454]

Harrop torque power or come single plane will all work.

The TP manifold is better out of the box, the Harrop is slightly bigger but will need some porting work in the plenum (other than port matching runners to the head). Which manifold comes down to how big the cam is. I'd go TP.

 

[Cava454]

The TP will be better suited to power levels less then 550HP. Above that its harrop and pro paw level. Doesn't mean a harrop won't work tho.

The TP is in no way better out of the box. The runners arent cast that crash hot. They have dags everywhere and in some case not square. But also that doesn't mean it won't work or make power.

Either way I'd recommend at least a port match, plenum work is another option.

I've read and seen some good things from the come single plane of late.

I have seen a Harrop for sale locally for $550 that's all. Near new.

 

[Cava454]

That's a bargain, get it. Drilled for injection?

 

[Not_An_Abba_Fan]

Yep, drilled already.

 

[Immortality]

That's a good price. I'd grab it.

 

[Not_An_Abba_Fan]

I missed this one....it was sold when I contacted the seller....I'll keep looking.

Well, motor came out yesterday and pulled down, apart from some big end wear on the bearings, it looks in pretty good nick. Very clean, no sludge. It's at 060 though, so pretty much maxxed. 3 plugs looked a bit oily, but all the pistons were pretty uniform in colour. Bugger all lip too so that's a bonus.

Just want to clarify the right cam though, seeing it's a 308 with VN heads and hydraulic lifters, is this the right cam?

The cam that is in there at the moment is this one



I can't find the part number on the Crane website, it has R A N in between the lobes in the middle of the cam, I'm assuming it's a Crane. The 112 would be the LSA?
