ha ha. thanks mark. is this a decent cam? i know your the guy to ask around here. i will be using the PRC stage 2.5 5.3l heads with the cam. and how much would i be able to mill these heads with that cam using the .40 head gaskets?

PREDATOR-Z

It is a very stealth cam, power come on after 4K rpm. IMO you should shoot for 11.2:1 SCR or so. So about 61cc chambers.
If you do not allready have the cam, there are better options with a bit less lift. Something with a power range of 1800>6300 seing you have a 99 block.
What intake do you have? and what are you looking for in a cam?

up to what compression can an engine be tuned safely and easily and not pushing it on 94 oct fuel?

PREDATOR-Z

It is more a question of DCR (Dynamic Compression Ratio) than SCR (static compression Ratio).
I run 12:1 in Dubai on 98 Octane (US 94 Octane) and my DCR is 8.9

well i am looking to make as much torque as possible with still being able to pass smog. i know thunder racings 224 camshaft will pass on a 114 but was just tryin to see what other cams are out there that will make good torque and hp numbers. as far as the manifold i was gonna use a slp ls6 manifold cuz it has all the emissions. but was also thinking of running the 78mm fast and drill and tapping were my egr goes. whatever one flows better will be the one i go with along with the 5.3 heads.

Just let our sales guys know when you order the heads & we'll make sure & mill for the chamber size you request free of charge!!
