What should I expect?
Got my parts list together and now I'm ready to start ordering stuff.
I've taken the motor out of my firebird and am sending it off to the machine shop next week. I will start a build thread once I get it back but I'm just wondering what you guys think about my combination and what I can expect.
I'm hoping for around a 10 or 10.5:1 CR.
Build list:
350 roller block .030 over (2bolt main, will have arp fasteners)
Hypereutectic flat tops (maybe not still determining my cr)
Howards cams 180255 (comes in 110 and 112 lobe separation)
Vortec heads 062 w/ 2.02in 1.60ex and a 'garage' port job
probably stock rocker arms
Hsr intake manifold
30# bosch injectors
It will all be professionally dyno tuned and a custom chip burned. My only drawback is the 2 bolt main but I don't really feel like running around looking for another block so if I break it, then I will fix it
. I have hopes for something close to 300rwhp but its going through a 700r4 so we shall see....
