Realistically how hard would it be to make an Lq4 put down more than 380+rwhp on a budget of $1500 without have to mill the 317 heads, as of to date I have (k&N CAI, magnaflow exhaust, fully built tranny which isn’t even broken in, and Wheatley tune) I have LT sitting in my garage but I’m waiting for auto cal before putting them on. I’m trying to build a truck with good hp/torque numbers not a 12s truck cuz it is 4x4 and a DD. Any info would be great

 

LQ4 with a tr224 cam full boltons should make 380 or close to it and be very driver friendly
Why no milling the 317s?
what about a set of 243 heads to up compression?

go in the dyno section look up truckshop

 

Easy.

 

stock 243 heads or worked 243 heads? i didnt want to mill the heads cuz the machine shop here charges over $400 hr and they quoted me 6 hrs
and im not payin 2400 for worked heads its not a 8 second project plus ive heard good things about 317 and i kinda want to keepa Budget

 

Holy **** wtf is wrong with your machine shop? You can buy some damn good heads for 2400

 

thats what im sayin im just trying to get a lil more out of my truck i told the ower, i asked him what he was smoking cuz at that price id take a change with a belt sander lol

 

stock 243s will up compression because of smaller cc chambers no mill needed
I can get 243/799s local for dirt cheap of NNBS trucks

 

with 243 i take it the compression will be some where 10.0:1 roughly and i take it i can use standard/stock length pushrods with the lq4 if the 243s are not milled?

 

How cheap?

 

compression will be closer to 10.8 to1 i wanna say
2-300 a set depend on what mood the supplier is in and if he needs cash
