Whats so bad about pushrods? They open valves, OHC open valves too.
DOHC? SOHC? The funniest thing was when insurance said that they would not ensure a stock 2t-g in my celica over the 2t engine because, and i quote "The extra camshaft makes it too powerful"
Using the 2t as an example, it's 99% the performance head, valve sizes, bigger ports, better chambers that make these motors perform over their standard 2t variants. If you could somehow make a 2t-g pushrod motor with the same cam profiles, head chambers and ports as the DOHC, and made sure you spent some $$ on good pushrods and roller rockers, there honestly would not be a thing between this 'pushrod' motor and a real DOHC 2t-g.
EXCEPT for COST.. it's simpilty cheaper to make a RELIABLE DOHC than pushrod performance engine
Part of the reason the 2t-g is DOHC is cause it revs high, and losing all those long rod links aids for a CHEAPER way to make RELIABLE revs, than to opt for factory 'beefed up' pushrod valve train. oh, and plus they gotta live up to the toyota rep!
V8's generally don't rev very high (well not in standard form anyway) so don't require valve trains capable of supporting high revs. 4cyl make thier power by revs, (or boost) so naturally OHC is the ansewer to a cheap, reliable valve train capable of high rpm.
and remember, we're all using the same 4 stroke cycle. That's 1800's stuff. someone just thought of a better way to open valves!
