406 sbc vs 383.

Similar HP, but the LS3 drives 1000x better. The 350 to get that HP was pretty radical with a high stall converter. The LS has a high stall converter too, but it has OD with a lockout.

Most generally, and all other factors being equal, a long stroke small block like a 383 will make better numbers with a 106 LSA cam vs. one with a wider angle ground into it. Your compression ratio is suspect if you intend on running that much camshaft. You really need 12.5:1 minimum to really utilize a cam of these proportions.

Depending on your combo, if the the cam is short and the engine can truly use more cam duration/lift you will see some gain from both intake and exhaust 1.6 rockers. basically if you have really good intake and exhaust system but cam is a little small then you will see overall increase in the entire power band.Build your 400/406 if it needs bored to right at 9.5 CR.
