Hi!

Im building a 500-600hp Cossie engine and have been thinking about getting billet main caps for it (the three which can be changed; first, second and fourth).

Ive just been pondering is there any need to change them? Or can i get away with the stock ones..?

Im going to run stock crankshaft, arp studs on main caps, long head studs, ~8,5-9 cr, ported head, etc. Revlimiter is going to be at 7500-8000rpm.

Thanks!

i've not heard of any of the big'ish power cars in the UK running anything other than standard, but i cannot be sure 100% on that

 

You wont need it on that spec.
