hello there, i have a normal aspirated ls2 that i want to modify in order to get more than 550 hp on the engine off course i want to have a high torque curve.the purouse is to take my car out on sundays and somethimes go to the track to make a desant time on the 1/4 mile
here are the parts that i have bought already but not yet put on;
.030 milled ls3 heads with flowed exhaust ports
eagle forged rods
JE forged pistons already designed for high lift valves
1.85 yella terra roller rockers
cam shaft with following specs; ADV DUR 276 292
DUR at .50 227 243
valve lift .613 .623
lobe sep 113.0
comp cam dual spring kit and stronger push rods
standard ls3 intake maniflod with throtlle body
standard oil pump with harder spring for more pressure
standardLS2 chain
i dont know if it was a good choice to have 1.85 rockers and on top such a high lift cam?

Not really. 550 rwhp on an LS2 with stock cubic inches and without forced induction is not a reasonable goal.

frederic

So how much do you think is possible?

jim2092

As an aside, where is Affligem? But 500 would be a max effort LS2 with heads, cam and intake. Why 550 hp?

frederic

Affligem is in europe, Belgium. Famous for its abbey beer
I just want to leave behind some porsches and ferraris here on the highway. I wil put this engine in my c3

Good stuff. May want to go with an engine not run by computer as the LS3 is. Lots of options there. 427, 454, etc.

I bought already an ls2 with a t56 and all my tuning parts. so now i ll have to stick with it.
