hey guys,
i can soon aqcuire a set of Z06 heads and Z06 cam brand new for about 800 dollars through a friend...
i have a 99 ECSB silverado with the 5.3...
how much of a performance increase would this add???
i currently have just the K&N intake and BORLA exhaust...
also is this a good combo to put on my engine for a decent daily driver HP upgrade????
thanks guys...
I think I would shop around before I bought the heads and cam from him for $800. You can buy a set of stage two PP heads for $1195 they flow 300 cfm at 600 lift. Just my my 2 cents worth. If you want at set of good heads I have aset of ported/polished 5.7LS1 heads with 2.02 intake and 1.57 exhaust valves. I just got them back from the machine shop I had them milled .005" to straiten them back up. I will sell them plus a LS1 cam for $450.
Just let me know if your interested.
