The STOCK 320 HP 350 TBI
 

Well I have mentioned it before and I finally found a brief video clip of one running.

For all practical purposes it is a ZZ4 engine with a "Marine" camshaft. For those not knowing marine engines, the "marine" roller cam is the same cam we know as the Ramjet. Its tiny at 196/206 @ .050, but runs a 109* LSA. With the L98 aluminum heads the engine is capable of 320 HP and 385 ft/lbs of torque. The intake is of a higher rise design than production truck/car TBI manifolds and has 2" bores to go along with the larger 2" marine TBI.

whats that liquid shooting all over the place ?

Re: The STOCK 320 HP 350 TBI
 

that liquid would be water, most marine engines use the water that they are driving in to cool the engine and just spray it out after it has passed though,

Ah ok, thanks i have no knowledge of marine motors :(

Re: The STOCK 320 HP 350 TBI
 

Very cool Fast355, any idea what ECM it ran? It sure would be cool to take a look through the .bin that was stock calibration for that motor. I wonder if those marine engines use watered down versions of the car ECMs (no pun intended) or just a standard one.

The ECM is the same unit thats on the Ramjets. There is software out there to tune them, but it is $$$

Oh, ok, that's a bit of a letdown. Oh well, cool engine setup though.
