Default experts opinions...

im new to the building a motor scene... im personally not building it i got a well rep mechanic around town to do everything for me since i dont feel like haveing to do the mess up and try again method... anyways my build is... 99 z28 camaro... ls1 block-243 heads with valve job, diferent valves couldnt remember what he put in... comp cams rocker arm trunion upgrade... .650 dual springs with titanium retainers... harden rods... torquer v2 cam... king bearings... forged scat rods... forged mahul fly cut pistons... ls7 lifters... ls6 ported oil pump... ls2 chain... ls6 intake... every bolt in the motor is arp bolts... mechanic says it will have 11.1 after deck and milled...... clutch is a stage 3 monster clutch with a light weight fly wheel... rebuilt 6 speed with mgw short shifter... strange 12 bolt 33 spline eaton posi with 4.11 gears... has 1 3/4 qtp headers to true duals 3" dumped at the axle with single chamber mufflers... lid... tubular pan hard bar, torque bar, rear lower control arms... strut tower brace... all pushing some 315s on the back........ will most likely get LMR to tune it...

now that you all know what i have in the process of putting together, i would like to know what people with similar build is putting down... i know i could of prob just turbo it and call it a day but this is my first build and wanted na dependable... anyways the research i have done so far looks to be only around 410-420hp and around 390-400 tq... dont really see to many 1/4 times.... so experts please chime in and let me know what yall think it would put down and what it will run.... thanks

Just depends on the dyno, but I would think 420 rwhp is a fair guess

One of our cars had that cam with untouched 243s and made 427rwhp and 385rwtq on a dynojet through a 6 speed and a 12 bolt. It will all depend on what dyno you are on though. Every dyno is different!

I agree with those numbers....headers and intake are gonna hold it back though.
