Heads, carb (650 or 750), intake, cam, headers, air cleaner.
Anybody have one? Cost? Listened to one yesterday and the motor sounded nice. Claims of 400HP by the owner on an '77 L48. He had also put true duals 2 1/2 exhaust on. Still lower compression pistons, so I'm thinkin maybe 300+.

 

Grayhook has the systemax II on his 79 w/355. It sounds good and is a strong-running motor. PM him for more info.

how can you go wrong with a name brand package that was designed as a total performance package? I would think it wouls be very balanced.

 

Yeah i got it, and love it! Nice kit. Had no problems at all with the install.
If you have a good short block all you'll need is a gasket kit and some rocker arms. I went with the holley kit,a short block from a local shop, new hooker headers and header back pipes, dynomax super turbos and a 750 carb that brett built for me, and got it all done and came in just at $3,000 but brett did me a smoke'n deal on the carb and the short block was a deal too.

I'm with you on that one, For the HP holley clame's you need 30 over bore and 0 deck

Did his sound like this?...http://media.putfile.com/Movie_000274

Run like this?....http://media.putfile.com/before-after

 

Big difference.....awesome sound.....

 

Not sure if you're doubting the HP of the kit or of the particular motor you heard, but 400hp with one of those kits is not that hard. A solid bottom end and the top side matched up with a good carb and distributor and your there. I have seen a lot of these kits or "packages" installed with good results and have not heard or seen of any bad issues-other than when someone couldn't tune the carb or set the timing, but that wasn't the motor's fault.

Thanks...sounds like the way I'd wanna go.

 

Hey larry I just wanted to piggy back off your forum for a minute. I was curious on how easy it was to install this kit? Is there a full name and does it have a part or stock number for this kit. Ive been trying to look it up on the Jeg's web site but I cant seem to find it.
Thanks a bunch gentlemen

 

I don't see them either, here is part of what Summit has just for an idea of what you're looking at.

quote from site...

The MAXimum Performance Holley SysteMAX II package, was uncompromisingly designed for the person who will settle for nothing but the ultimate engine performance package. The cam is more radical than the typical run-of-the-mill grind. Lift and duration have been made to be rather ''aggressive'' and and it makes great power throughout the RPM band. This cam is about as bad as you can get and still have decent manifold vacuum and low end throttle response.

SysteMAX Requirements:
Chevrolet 350 CID short block
4-bolt Mains
Zero-Decked
Forged Steel Crankshaft
GM ''Pink'' Rods, P/N 14096846, or equivalent
Speed Pro Flat Top Pistons, #844-L2417, or equivalent
Speed Pro Rings, File Fit
Holley testing was conducted with a 750 CFM vacuum secondary carburetor, #510-0-3310. A good set of 1-5/8'' tube headers, used in conjunction with some high-flow/low-back-pressure mufflers is definitely recommended. If you're running a beefed-up TH-350 automatic transmission then a 3,000+ RPM stall converter will help lower drag strip times. If you're running a TH-700R4 automatic transmission, a 2,500+ RPM stall converter will perform best. For all-around great street/strip performance a rear axle ratio of around 3.55 should be used. A set of the Crane, (#270-11750-16), roller rocker arms is also recommended. New, top quality gaskets for your specific application are required separately and are not part of the package.

what rocker arms did you go with

 

I used summit's roller tip rockers.

 

What kind of increases in the numbers could be made if you put this kit on a 383 instead of a 350? Also Grayhook what carb are you using?

 

I'm running a holley 750 mech. sec. dp that Brettmc put together for me. It has proform metering blocks and baceplate and i added some chrome bling to it. see my corvette pic's.
Go'n 383 i'ed bet you'ed bump it to 450hp atleast.
