The plate that fits between the oil filter and block sits too high, the centre boss holds it off the gasket. Are there different versions of this plate? (68 block for RHD, English/Australian version). I have pre owned ductile iron 273 adjustable rockers, they don't have a lock nut. Are they OK like that? does anyone do a lock nut conversion? TIA.

They lost the interference fit when he installed them into the arm. I guess if you are using an off the shelf pushrod, try them. If you have to custom order pushrods, I wouldn't waste the $.

Are they OK like that? does anyone do a lock nut conversion? TIA. Tig. You can get the appropriate screws & locknuts, but the rocker arms should be correctly spot-faced for the locknut. The original surface has high spots which can stress and break the screws. I had the loosening problem when I first tried using the OEM 273 set-up in race applications as well.

Tig OP master Joined: Jan 2003 Posts: 2,924 A shed in England	Thanks. However, I thought I might tap the block for external lines but was worried about stressing the block with tapered fittings. Am I being over cautious there? It's just a street strip 6000 rpm deal. With the car being rhd the oil filter is in the way of the steering linkages/box. The method chrysler used (steel lines and a huge block fitting) is rubbish (garbage), they leak like a ruptured oil tanker and you can't buy spares for them anywhere. Nobody do any lock nuts for these rockers? I'm just unsure about them, I had a similar set up on a F**d Capri (cologne engine) solid lifters but they kept coming loose Thanks again.

The guy that bought the car off me, is thinking of replacing them. I wouldn't want to use them with 400 hp. cheers Mick 69 Dart GTS 440 mopar .590 cam, Edelbrock heads, 3200# best et 6.45, 106.78, 10.14, 132.88 mph, 1.47 60ft best 60ft 1.36
