455 in a Land Rover

My experience is the same as knucklebusted. The cam lobe does not have much clearance to the rod bolt or rod beam lower flank area. Aluminum or steel rods? Sorry for your loss.

Hi All

Its been some time since I updated you on the 455 in a Land Rover.

Well things have not workout as I hoped.

The last time I was here I had installed the new cam etc and it was running nicely on the stand, freely reving to 6000rpm. So before Christmas I booked a dyno session.

The intial run was to 5900 rpm and gave a solid 500bhp. The second run stopped at 4200rpm when something definitely came adrift. The end result was a forged rod putting a large hole in the sump and the starter motor launching itself across the room.

I've spent many hours disecting the wreckage and my best assessment is that the cam snapped. So I'm not looking to autopsy this here, it is what it is, but it does mean I now have some nice 455 parts that someone may find useful.

Over the next week or so I'll be listing them in the 'For Sale' section. I doubt it's economic to post them back to the USA but someone in the EU or Ozz may be interested.

As a warm up here's a list of what I have:

TA Performance Street Eliminator heads with bowl work.

TA Performance Roller Rockers 1.6 ratio.

AED 850 HO carb.

TA Performance Rocker Covers in black with highlighted lettering. TA1325B I think.

TA Performance SP1 intake.

TA Performance Timing Cover TA1531B.

TA Performance Oil Pump Cover TA1512F.

Meziere Electric Water Pump.

TA Performance HEI Distributor TA691.

Progressive Ignition mappable distributor.

There are a few other bits but off the top of my head I cant remember them all.

Everything has been thoroughly checked and I'll supply as many photos as people want. Everything has about 4 hours of dyno time plus a few hours due to me just wanting to listen to it run

Interested in the heads and rockers. PM sent
