Although- you can hit those marks without any trick machine work ...383 Stroker. -5cc flat top pistons. w/ 64CC heads (pro comp aluminum) estimated compression from Eagle (bottom end) is 10.7:1. I think (??) the recommended plugs for the aluminum heads are Champion RC12YC (Autolite 3924); however the current plugs are a hotter plug Champion RC14YC (Autolite 3926). These plugs are a gasketed, .750" reach plug.A 383 will be a better general performance engine, particularly in a truck, because it'll make good low rpm torque with the smallish bore and long stroke, whereas a 377 is a better race engine in a light weight car because of the rpm (read: horsepower) potential.

The only problem i have with the 400 is the block. They came in heavy vehicles and got worked hard from day one.

While this block is more expensive, it's a new casting with four-bolt mains and 350-size main journals, which means slower bearing speeds over the larger ...This allows the use of most rods on the market without having to grind any material from them when used in engines with a 3.750 stroke crank, such as those in the 383 and 406 sbc engines, and this includes the Scat H-beam rods, as they usually have the worst cam to rod interference.The 383 is a bit more radical on the heads/cam combo but it still makes all of the power of the 377 but of course has a ton more low end grunt! The 383 runs the numbers with a 2800-3200 stall and the valvetrain doesn't take a beating. The 377 hit's it's best with @ a 5000 stall and shifts are closer to 7800 vs the 383's 7000 shift point.

ALTHOUGH i had a 355 with a big solid lift cam, and brodix 200race rite heads that was 11.5-1. changed the bottom end to a 383, dropped the compression to 8.5-1 (for procharger) and went to solid roller. the 383 would KILL the 355 motor for motor. in other words the low compression 383 would kill the higher compression 355. both can run well.

I would go for the 406 anyday. To me, if you can make the same power with a 6,000 rpm 406 and a 7,000 rpm 355, then the 355 is more likely to break bottom end parts due to rpm. Now, if you can afford all the best in bottom end parts, then this may not seem big.Building a sbc 406 Drag Engine. I just got rid of my fox body mustang & got a little 90 S-10 with a 406 sbc in it.

Other than a lot of expense, never noticed a difference in actual performance gains. the 6" rod 400 required a small base (.900) cam which was expensive.
