The V8 Owners Forum -

Depends on budget. Cheapest - file exhaust ports to match the manifold. Or send the heads to Roland Marlow at ACR Automotive for a proper doing. he did mine - there is not much he doesn't know about V8's.
My 4.8 v8 pulls 300 hp at 6150 rpm. Same torque at 4000.

I have just taken the cam out of this 4.6 block. It reads TVR 51.

Any ideas? Have replaced with a Piper 285.

Thanks

What is the best oil grade and type to put in a newly reconditioned R380 gearbox, running a Landrover 90 with a 4.8 litre V8, 300 hp, 300 ft/lbs, 1.66-1 transfer box (18mph per 1000 rpm)? Engine revs to 6150. Road use only.
