[QUOTE="tt335ci03cobra, post: 16173944, member: 68944"] If it’s 12psi, I see upto 760hp happening. Keep this in mind when you look at that 1L difference, the na lt1 makes 455hp at 6.2L. The na 5.0 coyote makes 460hp. 5.0 is smaller than 5.2. I have a buddy with a 10.5/1 6.3L built twin 62mm turbo ls3. 8” runner custom intake, heads, cam, etc. Makes 700whp on 10-11psi, my twin 62 8000rpm 5.3 modular makes 815whp on 10.78psi. Anyways, back to the big 3: Chevy: 455hp/6.2L Dodge: 485hp/6.4L Bullit: 475hp/5.0L Gt350: 526hp/5.2L Ohv is hard to get to about 80-85hp/L with very reliable and inexpensive parts. Mass producable and warrenty’d. Dohc can cross 90-95hp/L pretty cheap and reliably. This is due to better accuracy of inlet, compression, combustion and exhaust cycles. Thing is good luck changing a mother****ing driver head gasket in your garage or a mother****ing timing chain assembly with these 4 cam ****mobile motors. Been through that shit and am over the size issues. Give me a bigger push rod and I’ll buy some extra gas. Futur builds, I’m doing simple pushrods. Stuff breaks and the hassle of pulling a modular engine in and out is a tuff sell to me for the 12.5-17.5% of additional potential. [/QUOTE]
