How much power?

[blackbird1084]

Ok here's all the specs of the motor I'm getting. I'm wanting to know if you guys think it'll make over 425 rwhp?

JE 11.89:1cr@56CC FORGED PISTONS, SCAT 4340 STEEL 5.700" H-BEAM RODS WITH ARP BOLTS, SCAT 4340 NITRIDED 3.750" STROKER CRANKSHAFT, SPLAYED 4BOLT MAIN CAPS W/22 ANGLE AND ARP 4 BOLT MAIN CAP STUD KIT, LUNATI FILE FIT PLASMA MOLY RINGS, AFR 210cc LT4 STREET HEADS W/56cc CHAMBERS, PORTED AND POLISHED BY LLOYD ELLIOT, K-MOTION K-1100 VALVE SPRINGS, JESEL SHAFT MOUNTED 1.6 ROLLER ROCKERS, COMP-CAMS SOLID LIFT ROLLER CAMSHAFT .639 INT .646 EXH , 254/270 DURATION, 105.5 LOBE SEPERATION, COMP-CAMS SOLID ROLLER LIFTERS, MOROSO OIL PAN W/MOROSO OIL BAFFLE, COMP CAMS 5/16 MAGNUM PUSHRODS, CSR ELECTRIC WATER PUMP, PIONEER BALANCER AND PULLEY, 95-97 LT1 DISTRIBUTOR CAP AND ROTOR, MSD IGNITION COIL, EDELBROCK VICTOR EFI CUSTOM INTAKE, EDELBROCK BILLET FUEL RAILS, DELPHI 32LB INJECTORS BY RACETRONIX.
I plan on changing the cam out for something with a wider lsa but close to the same lift and duration. I also plan on swapping to 36-42lb injectors, my jegs 10% ud balancer, going back to my 4200 stall, using my ported edelbrock intake ( I want to stay in the ex street class), a 58mm tb, and get it tuned by Ed wright. The only other questions I have are will the 255 wally support this setup and is that 4200 stall over kill or just right? What lsa would be best 114 or 112? Lmk what you guys think.

I don't see why it wouldn't make 450hp if the heads are ported preferably competition port job and the intake to match. I also would run the cam on a lower lsa if it is a motor only car like a 106 but if your going to spray it the higher lsa is fine.

I think that you should give all you information to a reputable converter builder and let them tell you where they feel it needs to be. I think that 4,200 is a good starting point I'm sure you won't need to go lower higher if anything.

Example my car was cutting 1.42's with about a 4,200 converter and I have loosened it a touch trying to sixty a little harder.

I bought a motor, it has good parts on it, and I'm going to stick it in my car. Will it make 425rwhp after a parts swap that includes a cam with a wider lsa? Better? Lol

[blackbird1084]

And Badhawk that's the converter I used before when the car was cutting mid-high 1.5's with my old setup and dr's. I want to drive the car often if possible. So something with a wider lsa will be more street friendly. I really want 10.9's out of it.

Like I said it should not be a problem with that setup.

I drive my car where ever I want but, it will definitely be more street friendly with a wider lsa. The car will idle better for sure. Where does that cam make power to ? Do you plan on spinning the motor to the max of the stock computer because that cam is going to want some rpms.

[blackbird1084]

Yeah I might look into an ls1 PCM swap so I can get all the rpm I can out of it.

[Badhawk]

Solid roller with an LS1 pcm swap spin it to say 7,500 + your car could be nasty and yet very street-able.

[blackbird1084]

What all is needed for an ls1 PCM swap? I know it needs a 24x-58x reluctor wheel, PCM, coils, wires, and tune. Is that all or is there anymore I need to be looking for?

[blackbird1084]

Crap I didn't know Ed wright stopped dyno tuning! Ok does anybody know of a good tuner near Missouri?

[Railrunner]

Justin at MC Racing in Mission, ks Modified by KC in KCMO and Super Tune in Olathe i believe still tunes. I would say House of Boost but they dont take personal cars anymore....
