ya will keep it updated, dropped the heads off to get some valve work done.. iono if a 5 angle valve job is worth the money but every bit helps i guess..my plans and goals for this setup is to be low 11's high 10's with a 9" and 4:10 gears. well when i get the 9".. all motor. will port the heads when i get more money, but as for right now they should be more then enough.. and who know, maybe in the future i will spray :-)

really would like to see 450+ (rwhp) all motor, but that might be asking for too much.. crossing fingers! just ordered hp tuners, so going to do a race gas tune so i can squeeze every little bit out of this stock block i can.. then have a 91 tune for daily driven

There is no point in running race gas unless you have a higher compression that calls for it.

yeah for sure a race gas tune is more agressive than a 91 octane tune.

if you dont mind me asking what kind of setup is this thing? and what kind of powerband is it designed for? this is something close to what i want to run with prc 243 stage 1s/duals and LS6 intake. only thing i would change for my setup is go to a 112-113LSA to kill off some of the lope. thats just for me tho

if you do some searching there are a few good threads on "aggressive tunes". some of the hardest running N/A setups use alot less timing than you might think. some run less than 26 degrees on an efficient setup. timing isn't gonna be the savior some might think

setup is for ls6 heads/fast intake/stock gears/6speed/3500lb car.. and might spray in the distant future. the power band should be in the higher rpms, but the cam is advanced to bring it down to more mid range.. so it isnt a pig in the mid rpms.. should have a nice curve i hope, only the dyno will tell

imho i believe you will need to mill those 243 heads a bunch to benefit from race gas.

oh i know timing isn't going to make my car gain crazy numbers.. just trying to squeeze as much as i can out of it. and a race gas tune should get me closer to my goals then a 91 pump tune.

I don't think your gonna gain much if any top end by advancing the timing. You need to retard it back down when you get past your midrange.

well i know the 243 heads raise compression a lil more then the stock 241's.. so its already getting a lil more compression from the get go. then if i mill the head will raise compression even more. would like to spray in the future, and i know some higher then stock compression engines run nice on the juice.. but thats with a worked engine with at least forged pistons.. never sprayed a stock block ls1 b4.. but i know my lil 302 5.0 loved the stuff, sprayed a 150 and it asked for more. if i was running a standalone fuel setup, how much juice could this lil engine handle with the appropriate head studs and head gasket?

yeah just letting you know you should look to mill the heads. Get your DCR on the upper limit of 93. thats where mine is. i know with some racegas and n2o, it will go apeshit.
