Power Upgrades For The ZZ4 350 H/O Engine
Option 1 (385 HP): A very popular combination that’s perfect for street. It puts out 385 HP / 410 lbs of torque. The power gain comes from custom ported ZZ4 cylinder heads and match ported intake manifold. Requires 750-CFM carb and headers _ _ _ _ P/N SCZZ4-1 Option 2 (395 HP): Option 1 included, plus an Edelbrock RPM intake manifold. If you have hood clearance, this is an easy 10 horse power increase to 395 HP / 416 lbs torque. #7101 with RPM square flange_ _ _ _ _ _ _ P/N SCZZ4-2S #7104 with RPM Q-Jet_ _ _ _ _ _ _ _ _ _ _ P/N SCZZ4-2Q Option 3 (400 HP): Includes options 1 & 2. Plus the installation of roller rockers with a ratio of 1.5. Power increases come from less rotation torque, more precise valve lift, and less valve train wear. Oil temperature will also decrease. We reach the 400 HP mark with 420 lbs of torque, with this option. Gm aluminum guided roller rockers _ _ _ _ _ P/N SCZZ4-3G Crower stainless steel roller rockers _ _ _ _ _P/N SCZZ4-3C Option 4 (420 HP): Includes options 1,2 & 3. This option requires a cam change. We install the new LT-4 H.O.T. cam with 1.6 roller rockers. This brings the horse power to 420 HP / 427 lbs of torque.
Option 5 (440 HP): Includes 1, 2, 3, & 4 above. This is our most powerful H/O engine which requires a single plane intake manifold (Edelbrock Part #2975 Victor Jr.) also an increase in valve size with manley stainless steel 2.000” intake and 1.560” exhaust. The engine was struggling for more air flow and that’s what we gave it, creating 440 HP / 437 lbs of torque.
“This engine is the ultimate small block street warrior.”
P/N SCZZ4-5 Option 6 (395 HP): SUPER H.O.T. ZZ-4 H.O.T. Roller Camshaft, 1.6:1 Roller Rockers, 395 HP @ 5,800 RPM / 415 Ft. Lbs. @ 4,300 RPM. This option is for someone wanting just a little more power than the stock ZZ-4. Consult with a GMPP sales person for more information. P/N SCZZ4-6 |

Note* This is the additional cost if we install the item. Note¹ When cam is being changed there is N/C for installation labor. A Small Note About Upgrades - Part prices for upgrades are with exchange of existing parts for the upgraded parts. In other words, Chevrolet keeps the original parts and substitutes the upgraded parts. This allows Chevrolet to sell the upgraded parts, as an option, lower then if you bought the upgraded part by itself. If you wish to keep the original part along with upgrading, you will have to call our toll free 1-800 number for the cost. Our list of options are only what most people are looking for in options, but you are not limited to the list of options shown. Our Race Shop can do almost anything that you request as long as it is physically possible. Putting V8 heads on a V6 block would be an example of not being physically possible. Our Race Shop can build a crate engine to your specification with pulleys, brackets, engine mounts, all the way to a complete turnkey engine ready to drop in place that will meet your application needs. Call our toll free 1-800 number to talk to one of our counter people and they will be happy to work with you and help you determine what you will need for your new engine to fit your application and meet your desired goals. |
