right now i have a bolt on LO3. basically i bought a bunch of new stuff for my motor im gonna list it all. im curious as to how much power i should make around with all of this, or what i should expect in the 1/4

305 block
89 MAF tpi setup
22ib injectors
350 computer
187 heads (ported or unported havent decided if its really worth effort maybe ill port just the exhaust side i dont know yet)
zz4 cam
manley springs and retainers ( will accept .510 lift on stock head)
screw in studs
dual fan setup
255 walboro
airfoil (i know does nothing)
slightly ported tpi base
ported tpi plenum
3.23 disc brake posi rear
headman headers and y pipe
dynomax catback
gutted catalytic converter
AIR delete

i think thats it. not positive since i have so much stuff just lying around. and no im not going to buy aftermarket or better heads i have faith in what i have dont try changing my mind.

 

anyone with an idea?

 

ill try bumping this one more time since a bunch of these same threads are popping up with answers now

 

highly dependant on the heads ported or non and how far the manifold is ported but, i'd say 13.9-14.9 in a quarter and 240-275 hp depending on a few variables. g/l

 

well the heads will be ported. on the base i only smoothed the casting flash in it and opened up the entries from the runners a tad for smoother airflow.
