Next steps... new project - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

RealQuick · 02-15-2018, 10:04 AM

After pulling my SBE LS3 to put in my GTO, and I just sold the Huron Single Kit, I am starting a new project for the Camaro.

here is the plan...

Engine:
TSP LS3 427ci (Weisco slugs, TSP crank, Callies rods, ARP 2000 and Mainstuds)
10:1 SCR
AI280CC LS3 heads/BTR.660 Ti
235/231 .6XX/.6XX 115LSA (may change this, but worked really well on the single setup).
OE Lifters
LS3 rockers with Straub Trunnion upgrade
Melling Oil pump (hi volume)

Fuel: 93 octane
1000CC injectors
ZL1 Pump
ADM FPCM
Alky Control Dual Nozzle Kit (15+5) - May go up on the 2nd nozzle.

I made 817rwhp on 376ci at 60% DC when running meth, so there is a little more room, but it wont get me to 1000rwhp. I know I will need to change out the pump at some point, but for now I am gonna run it and just make whatever power I can while supplementing with meth.

Power Added:
Twin Turbo Low mount
Huron or AGP (undecided)
Probably something in the ballpark of 60/62 turbos

Ignition:
Granatelli coils (already have them)
br8's
Wires TBD

Tranny:
Stock M6 tranny
Street Slayer Billet Twin
New Slave
Tick speed bleeder

Rear:
Stock for now
3.45 gears

DSS aluminum 1 piece driveshaft

Tires:
20x11
Nitto 305/35-20 NT05R
Didnt hook worth a shit with the single kit on low power, so I will be upgrading to something with a little more sidewall. I just dont want to have to ditch the rear stock brakes... so I think 17" wheel is the smallest I can go.

Obviously there are lots of things I should upgrade and build for strength (fuel system, tranny and rear), and as money comes I will do that. For now I need a new motor and turbo setup, so that is the focus first.

The setup looks good. Ya, the NT05R's didn't work out well for me. The M/T R's have been awesome.

What size M/T R’s?

AGP Turbo · 02-15-2018, 01:14 PM

29" M/T ET Street R on an 18" rim fits and works pretty good all around. Same tire on a 15" is insane strait line traction but a wobbly, bouncy, shit handling bitch. At 200mph, they will help you find Jesus.

AGP Turbo · 02-15-2018, 01:16 PM

Is that engine a 4.1" stroke?

Might want to reconsider the 427 ls3 with boost. Probably look into a fuel system and bigger injectors also.

Punisher_ATX · 02-15-2018, 02:37 PM

Boosted 427 is a bad idea. Id rather keep a stock crank and put in TSP I beam rods and a CP carillo piston. Better bang for buck combo imho.

Why is it “a bad idea”. Care to elaborate?

TRC-SS · 02-15-2018, 03:04 PM

I don't know why but I've never heard anything good about boosting an LS7.

Most takes the LS3 and bore it out to a 416 stroker and forge away a monster

Punisher_ATX · 02-15-2018, 03:05 PM

With the longer stroke you are getting more extreme rod angles and as a result you are going to be putting extra stress on the bottom halves of the already short sleeves. Over time the sleeves will begin to oval in shape and eventually you will have a failure. Will this happen in 5k miles or 100k miles. dont know but it will wear out a motor MUCH faster. Id NEVER go more than a 4" stroke on a stock block LS motor. I prefer the stock 3.622 stroke.

Reason boosted ls7's are bad for boost is the cylinder walls in an ls7 are thinner than the walls in a cheap hotel room. 7psi is about the limit lol

Crank stroke vs. cylinder sleeve length.

The 4.1 stroke pulls the piston farther down the sleeve. Has it been done before? Yes. Does it always blow up the engine? No. Will the earth tilt off it's axis and hurtle into space, killing everyone? No, but it might destroy your bank account if you have to rebuild again. If you were NA, I'd say yes as there are a few builds on here that have successfully done it.

I'd go with a 4" crank and have a 416-418. The 9-11 cubic inches you lose will never be missed and you'll have a better setup for big HP.

I can't find it but I've seen a chart that shows the different block (OEM and aftermarket) sleeve lengths.

If you got creative with a 6.098 rod and piston pin placement, you might be better off. Still, I'd go 4" crank and not worry at all.
