500 Rwhp Possible?
500 Rwhp Possible? I am not to knowledgeable about the lsx motors since i started with an LT1 but I am just wondering if i will be able to pull 500Rwhp out of my build.
408 iron stroker.
12cc pistons
L76 intake 90mm tb
42# SVO injectors
L92 heads milled to 65cc chambers and some exhaust porting.
patriot gold springs
custom street able cam
dyno tuned
built 4-l60e with 3600 stall
3.73 rear gear.
stock LSx WP
no ac or emissions
just a basic build looking to make good power.

biggest factor right now would be what size your cam is and how well it matches your heads... its gonna be a little tougher with an auto and a stall.... and I heard the l76 intakes were somewhat limiting when used...

Ya i knew cam size would be a factor I plan to have one specked when I am further along so i cant really say size probably will be looking to spin to 6500.
I will probably be looking in the 238-240s range 600+ lift

Going over the 500 RWHP barrier is doable.
On my little 346 Ci. NA we obtained 511 rwhp AND 455 RWTQ...
Not a cheap way extracting those # from a "small cubic engine", but it was an interesting challenge!!!
Drivability is impressive, mileage is in a positive range, fun is immediate every time I jump on the right pedal...
I wrote some accurate instructive threads about my complete building and tuning process with graphs and videos, it may help in your decision.
