ok combo questions? about LQ4
firts if you want to make decent power you need more compression. second if you are doing this on a shoestring budget(hard to do on a swap) then ditch the truck intake for a Z06, keep the 317's but mill them down .030 for a little bump in comp and go with a 224 cam. youll hit 340rwhp.
Now if you want serious ponies......... then look at a set of PnP 243's milled down to 62cc, Fast 90/90 with a nice thumper of a cam in there and you'll get your cookies quick.
