What you guys think? Current motor has 95k on it and I want to heads and cam it then run it till it blows and put in a 8liter monster.

Can do that or buy a ls3 motor and put it in with a cam

How much power can a ls3 hold in stock form before it fails?

a cammed LS3 can make 450rwhp ...same as a H/C/I LS3. Probably have a better torque curve as well.

I'd go with the LS3 for sure. people have taken them past 600whp on the stock block safely.

Ls3 is a decent swap... I would do a 6.0 lq9 with l92 top end... Slightly heavier and barely less power, way cheaper.

Cam only should make 450Rwhp, ported heads should allow 500.

lg g6x3 cams are putting out 500 rwhp in ls3 5th gens
