Guest Anonymous Posted November 7, 2001 Share Posted November 7, 2001 Would the 4V or 2V heads be better with a twin turbo setup? I've been offered a pair of 4V heads, but havent decided if i should jump on them or not. Also do they fit the windsor block, I've got a 351 clevo with stock crank and bores, but Im tempted to get a mates 351 windsor for the wieght savings, if the heads will fit i might try to swap my clevo for the 4V heads, since i had a mate pay $500AUD for a 351 clevo crank I might get the guy to go for it. What do you guys think? Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted November 7, 2001 Share Posted November 7, 2001 The heads you'll "Need" all depends on your expectations & the parts you use to build your engine...which in turn effect the airflow prior to the intake, after it enters the intake/mixing w/fuel, combustion chambers & the exhaust. Every part on the engine effects airflow; your question, albeit in earnest, is too general to give a thorough answer. What I can tell you is that Corkey Bell's book says that any "Stock Set Up" can handle a 7psi boost w/no other modification. Your cylinder heads will effect when your peak power is reached, while your pistons/cam/intake/Fuel systems determine how quickly you reach that peak (broad powerband -vs- peaky powerband) & the turbo you choose will determine how efficiently your engine's peak power is amplified & how efficiently your engine is "Launched" toward that amplified peak.
