The SSS air box is probably small for a race engine but adequate for a road car. The volume given is for a race plenum used on 2 litre touring cars The main problem would be the distance to the opposing wall unless you had really short ram tubes.

Errol, I was planing on cutting up a 510SSS air box for the twin webers,and changing the square air intake to a big round (3") one and running a tube to under the rad . Going by your 2.5x engine size it wont be big enough? I never used any sort of air box before just air horns,I biffed the socks as too mesy looking,Plus a C&^t at tunning time(every two weeks) Malcolm E Smith wrote: > Nat, > Plenum volume should be at least 2.5 times engine capacity (ie 5 litres for > a 2 litre engine).
