ok these requirements...

Smog legal (california)
Natural asperated (last option)
will be daily driver...

so i will probably pull my motor out and get a few renches together... what all should i do while im in there... i wanna build it as powerful as i can. it'll probably be in a year or so when the car is paid off, thats when i'll have no money issues. but i wanna get a under 12 seconds if i can.

its stock. at the moment.

 

you wont need to pull the motor and go all out to go sub 12's. Just a good head/cam combo

 

let me deck it out... sorry im a newbie to how much power cams add... but i wanna reinforce whatever to handle supercharging (much later down the road) and get as quick as i can.

i wanna change the valve springs and what not to get to 6500 rpms...

 

305 cam
Longtubes (Mac midlengths or the good SLP shorties if you cant pass visual)
Hi flow cat
3" Y pipe,
3" cat-back
2800+ (as high as your comfy with) stall converter
CAI
Ported Heads

~350+ rwhp, mid-low 12s, emissions friendly

 

Light is the key word. Light rods but not aluminum, plus they have to be strong. I myself wouldnt go past a 4.030 bore due to cylnder wall thickness. Probably a 9.5:1 to 10:1 CR if your gonna supercharge it. tiny cam if emissions is that bad.

 

why dont i want a high compresssion ratio for supercharging it?

would supercharging give a lot more power with higher compression ratios?

what accually defines the compression ratio? isnt that mostly based upon the heads and the cam?

also w/ h/c combo, lt4 valves and springs intake and whatever else lt4 includes excluding cam and maybe head., 383 stroker kit, supercharging

what kinda flywheel hp would i expect?
