that puts out 400 HP?

that would be good horse power for a s 10!

yes it is and that's what the 604 is,the 602 is 350 HP

To get a 350 small block built to put out 400 horse would be huge money. Why not buy a 604 crate to drop in and it would be around 3-4 grand complete. If i also put a 4 barrel on it say a 850 dual pumper...how many more HP would that add based on if it just had a holley 500 2 barrel?

400 HP is with holley 650 4 barrel and stepped updraft headers on a dyno
not sure how a 850 would work on it

have found that if one over fuels the hp will drop, just an idea for you mike see if any of the teams have their old open small block for sale at a decent price. ps point of order guys they are engines not motors, motors are electrical, jusst being an a..hole
