Stealth Camaro

Hi guyz

I have 02 Camaro SS M6/3.42 with forged forged piston/rods, PRC 5.3, EPS baby cam and FAST 92/92
They car made great power N/A ~ 428RWHP/410RWTQ and 600+ with 150 shot

I enjoyed how the car drives and idle stealthy like stock, never plan to go to track only using it on the streets and race from a roll

I like N2O but the fact says that I cannot go bigger shot on my LS1 block,
and I wanna a 500+ RWHP and near 500 RWTQ in my N/A power with small to mild cam. Planning for 250-300 shot

6.0 bare iron block is in my garage, so 408cid will be my goal but I read a lot threads about weight and how it will effect the performance of the car !! .. I'm not doing drag racing.. only 50+ MPH roll and spray .. so I don't think the weight will be a problem in my situation ..

I'm not from US, and down here in my country Supras and Skylines with 750-900 RWHP are alot .. I know they are dyno queens but they are really fast at long distance

If I go with 408cid here will be the list

- Callies/Diamond Rotating assembly from TSP ( 11:1 ~ 11:4 CR )
- WCCH L92 Heads
- Ported FAST 102 w/ Direct Port for N2O Outlet
- Custom EPS cam
- Fully ARP Studs & Bolts

What do you think guys ?

If you're doing roll racing are you sure you don't want a SC or turbo?

I would take nitrous over a blower for rolls, turbo would be best though.

I would go 416 l92, save some weight, already have the l92 heads to port, more cubes.. but since you already have the block it would make sense to do 408.

Yeah sounds like the bigger cubes is what you need.

+1 on LS3 416 or 427

But if budget is a problem go with 408 and try to avoid spining due to weight transfer

Why dont you spray more than a 150 shot if you have a forged motor?

was thinking that too..maybe bump it up to a 200 shot

any more details about your build ??

I really don't like to spend those amount of $10K for FI & fuel system without the engine it self ! .. plus I raced a lot of SC ls1s and show them what does N2O really mean

416 sound great but not budget friendly ..

I already have all the available suspension mods ( K-Member , AA, TA, ... etc )

1. I have plate setup, so spraying more than 175 infront of the intake isn't something I will do one day (I really don't like to use fire extinguisher lol ) ! going direct port in my 346cid setup is waste of money since ls1 block safe power is around 600-700 rwhp ..

2. the purpose of the swap to 408cid is to have more power N/A

I'm not sure why people talk bad on the extra weight of the iron blocks.. The real question is do you need a strong sturdy big cube motor or not?

Wont the ls1 block handle more hp than that?

It seems like you got one strong car. I agree, i would just up your spray to a 200 shot. TRMIN8R was spraying a 200 shot all day long and he was on a stock bottom end.

+1 in keeping his current setup and save up for stroked LS3 or LS7
Don't add weight to your car front end ! you should add power to lift it !

Thanks guys for you comments

So guys 408cid is waste of time/money ?? Is it really that the 100lb make that difference in street car ????

The 408ci looks good but avoid the l92 hype. I removed mine for trickflow 235 and gained 20hp and 15tq under the curve. Same peak power but my car went faster at the track. The l92 heads out flowed the tfs according to flow data sheets. Have the block set up for a 300 shot and have fun.

go with the 408 build I have a iron truck block 402 its stood up to all i could throw at it so far been hitting it with a 200 shot off the plate setup.Im in the process now of putting a direct port nitrious outtlet has some killer ones.On the hit these nitrious cars leave like a bat at hell

I'd say go for the 408 in iron, 100 lbs from a roll is not as bad as from standing start.

As for heads, the WCCH L92 heads are great but will require you to shell out a bunch for yet another intake. Given you already have a pretty good intake, you may want to stick with cathedral heads - AFR, TFS or MAST may be your best option. Add up all the parts before making your decisions.

i vote keep the forged 5.7. you were talking about doing a direct port, id do it to what you have.

then when that gets old...then upgrade.

i would think a forged 347 with a 2-300 shot would be plenty....maybe because thats what im working on.

i think the weight difference is closer to 80 lbs than a 100, but for what you want to do (street driving and roll racing) you'll never notice that weight difference in a million years! In fact i believe the difference was so small that chevy used the same front coil springs (SS/WS6 not included) for the LT1 and LS1

i just looked up some part numbers, and the same part number for front coil springs were listed between a 94 Z28 and a 02 Z28
