For $40 you can find out for yourself.
Stick it in and come back and tell me I'm all wrong.
Can work real well with then right combo and tuning changes.
if you want a rough racey thumpr idle It won;t happen with this cam.
But probabily will need tuning changes timing fuel curve and a looser converter stall
and definaly will want gears.
This cam is not the same or close to a factory LT1 or even th LT4 cam.
These cams had shorter duration and less valve overlap.
Even these used a high stall gears 10;1+cr and or a manual transmission.
This has a big effect on the idle and low end engine torque.
Idle stability in gear with low stall (stock) converter.
especially critical with TBI EFI. Cams really mess with the TBI.
wider 116+LSA ='s less valve open overlap nicer idle
narrower 112LSA ='s more valve open overlap degraded idle quality and low rpm performance.
the ZZ4 with narrower LSA combined withe more intake and exhaust duration has a lot more valve overlap than
any of the LT-1 LT4 cams shorter duration and wider LSA's ='s less valve open overlap.
some people learn best by mistakes.
The 305 TBI motor is optimized for low rpm runing. with small cam and swirl port heads low compression.
low gears 2.56:1 low rpm running in OD for fuel efficiently.
