slammedbowtie Posted November 2, 2008 Report Share Posted November 2, 2008 there is a guy in town with the same truck but reg cab, 5 spd manual with a worked 355 and it runs 14.7 at the track. not bad. i think a 383 would be a nice motor to have in that truck. not ridiculous and still daily driver friendly. if you really want to spend more and go faster supercharge it Quote Link to comment Share on other sites More sharing options...
ripsass Posted November 2, 2008 Report Share Posted November 2, 2008 I really think oyu would enjoy the 620 HP version of the 572 more in a truck. You need torque to get a truck moving, and the 620 engine will make a lot more torque than the 720 and at a much lower RPM. If you are just going to drag race it, then the 720 is an easy choice. But if you will actually be driving it then the 620 will be way more satisfying in a truck. Plus feeding the high compression engine race gas would suck. You can not just "add a bounch of octane booster" to premium... Quote Link to comment Share on other sites More sharing options...
BigCountry Posted November 2, 2008 Report Share Posted November 2, 2008 (edited) Big-block performance with torque to spare.When you're ready to really step it up, it's time for the GM Performance Parts ZZ572 and it's massive 620 horsepower and 650 lb.-ft. of torque! This is flat-out, the baddest street Rat available that still happily runs on pump gas. The ZZ572/620 features 572 cubic inches of pure big-block and ships to your door in the coolest collection of orange, chrome, and aluminum you've ever seen. There are several custom-designed components that make the ZZ572/620 the king of the street. It has a strong, 4-bolt block that was created with a 4.560" bore just for the 572" displacement. The 572 block is fortified with a forged crank, forged rods, forged pistons – everything was designed to offer you the ultimate big-block experience. To feed all of those hungry cubes, we topped it off with a single-plane intake manifold that has been port-matched to the rectangular-port aluminum heads. A custom, hydraulic roller camshaft uses .632" lift perimeters to lead the charge. We make no apologies if the loping, aggressive idle of this camshaft attracts attention. The Deluxe ZZ572/620 comes complete from oil pan (with windage tray) to carburetor, including an 850-cfm Demon four-barrel, HEI distributor, red spark plug wires, aluminum short-style water pump, and automatic transmission flexplate. It's the ideal combination of big-block parts –designed, validated to GMPP standards, and tested in real world applications. *Applications have not been validated. They are merely suggestions of how you might enjoy your GM Performance Parts crate engine. Some applications may affect engine warranty. Some applications may not be emission legal; check state and local ordinances. The ultimate beast!When our GM Performance Parts engineers sat down and designed the ZZ572/720R, we told them to build something nasty. We think they accomplished that mission with a resounding 720 horsepower and 685 lb.-ft. of torque –creating at the same time the most powerful big-block crate engine ever offered by GM Performance Parts. We took the ultra-popular ZZ572/620 pump gas street engine added 12:1 compression pistons, a hotter camshaft, and our rectangular-port aluminum Bowtie heads with stiffer valve springs to work with the new cam. The block is the Gen VI tall-deck Bowtie block which was designed for the 572" application. The solid roller camshaft is a .714" lift magic maker that aggressively feeds the air/fuel mixture into the hungry, high-squeeze, stroker big-block. The ZZ572/720R is rated at 720 horsepower at 6250 rpm and 685 lb.-ft. of gut-wrenching torque at 4500 rpm. The short block is built with a 4340 forged steel crankshaft, shot-peened forged steel rods, forged aluminum pistons with full-floating wrist pins, stiff dual valve springs, and a louvered oiling windage tray. Our Deluxe ZZ572/720R ships with a 1090-cfm Demon four-barrel carburetor, tall-deck single-plane intake manifold, HEI distributor, aluminum short-style water pump, and 8 mm spark plug wires. Distinctive "572" cast aluminum valve covers complete the package. All you need is a GM Performance Parts lightweight starter to fire it up! *Applications have not been validated. They are merely suggestions of how you might enjoy your GM Performance Parts crate engine. Some applications may affect engine warranty. Some applications may not be emission legal; check state and local ordinances. Like everyone has said, the 620 would be the best choice. 12.1 comp and a .714 lift cam would be crazy in a daily IMO. Not to mention the difference in price... List is about 10k for the 620 and about 19k for the 720..... I say do it, if nothing else, imagine this sitting between your fender wells.

Fireman31 Posted November 2, 2008 Report Share Posted November 2, 2008 i think a 383 would be a nice motor to have in that truck. not ridiculous and still daily driver friendly. I believe GMPP actually makes a 383 stroker crate motor that will probably bolt right in..... Quote Link to comment Share on other sites More sharing options...
