FWIW.. 500hp NA isn't too bad on a stock displacement shortblock, it just takes a killer topend to do it & keep it driveable

it just requires badass heads..........and our LTX's have very limited head choices.
if someone could get a good price on converting regular sbc heads to reverse flow cooling so they fit out LT1's, then it opens up a whole lot more power for us.
for $1999 complete (springs, locks, retainers, valves) brodix makes a set of 18* heads that work with regular 23* valvetrain components. (but you still need a modified intake manifold and roller rockers.)
they flow 320cfm out of the box, and with porting much more.
the low/mid lift on these completely destroy any numbers from well ported LT4's, and better than AFR's too.
but i guess converting heads to fit the LT1 is a major expense?

i dont know, youd be hard pressed to be limited by a set of AFR220's and a quality port job.
there are cars pushing over 900hp on LT1 castings (not NA)
i know someone personally pushing 700+ rwhp on one with a blower

hey 396,383,409 lt1 are great if thats your deal I personal rather have less amount of torque down low that way you are constently getting wheel spin off the line. I know so one will say I have a stroker and it dead hooks. well come to houston I will give you a whole box of freaken cookies. I rather scream up top. as of 8000 plus rpms. I even was tring earlier to find a smaller crank the 3.48 some but I failed to find it.

those brodix18* flow 320 out of the box and cost $1999.
but im guessing the other $1500 you save is atleast what it costs to make them fit our LTX motor, and have the intake modified.
either way, you spend a buttload of money.

if you want 500 rwhp from a 350 you need AFR's alteast 195's fully ported by a very good head porter. A sheetmetal intake ($2800 from hogans or moreperformance). 215cc raised runner heads only cost a few hundred more then 195's and can flow 330+cfm.. why not you need a sheetmetal intake anyway. how about some tuned headers?(hookers,+4-2-1 collector). thats a pretty expencive top end package. you can prolly make 500 with a hyd roller but if you gonna spend this kinda money just get a set of shaft rockers, awesome springs, solid lifters w/ a solid cam. oh dont forget a rev kit..
