More Questions on Camshafts (sorry !)
Posted: Sun Jun 22, 2025 12:43 pm
Hi All,
I have (finally) sorted out much of what I needed to do work / house / 4x4 wise and now the "Want to do" for this question has sort of made it near the top !
I have a John Eales 5.2V8 Triple plenum V8
This was built some years ago for a 4x4 comp safari racer, quick spec is :
5.2 V8
Billet Crank
Arrow Aluminium Rods
Forged Pistons
Massive ported heads
JED Custom inlet and trumpet & Custom triple plenum intakes
Dakar Exhausts
H218 Camshaft (John advose me last week) with solid followers
and custom exhaust made to JED specs and advise
Front end is from a 4 Lire serpentine
Ali sport custom Rad full width Alisport custom Oil Cooler EWP150 and 4 x Spals
Now, .....whilst it was in a rear engined racer...... its now in a 2.5 Ton Full Bodied road legal Land Rover Challenge truck 90, and obviously engine is in the front
John re linered it (was bought a a wreck) - and its been rebuilt and Runs MS2 and is all mapped.
Problem is / I am wondering as to if this H218 is really suited to its new home?
Whilst I know the old "No susbitute for cubes" bit, I am wondering if a H218 is more suited to "Racey" use vs Road and off road low end mid ranage use & low end grunt.
John also advised that revving these too hard is not the best of ideas, and so the seed is in my mind as to which cam if not this one ??.
Camshafts / timing / duration etc etc is something I have never really understood, and Yes I will possibly ask Jon his thoughts as well , but meantime I thought I would ask amongst those who do know about cams their collective throughts ?
What I would like is to have lots of Low and Mid range torque.... and yes ok at the expense maybe of the Higher RPMs ...
Question is should I stick with the H218 (maybe peeps could advise how close this cam is to what I am looking for ?) and / or what other cams would suit ?
