400 sbc builds.
I got my 400 the other day. Trying to get a idea on what parts to use. What kind of builds do you use with your 400?
Looking to get around 350-400 hp/tq at least. My budget is about 3 thousand maybe more.
what do you want to do with it? what vehicle, gears tranny? octane?
you can do quite a bit with $3000. If you have committed to this amount have the block bored, line honed and decked.
Get a nice internal balance crank and dish top pistons. Decent aluminum heads can be found on ebay for $800 or less, a 185-200 cc runner will be ideal, I'd like the 200cc's personally. Air gap intake and a cam with around 235-240* @ 050 and as close to 500" lift as you can get with that duration. 2500 stall and it will make serious power. Basically what Stroke said :)
Thats for the help.
I agree but I would go for flat top pistons instead of dished. No need to give away compression. Pump gas will work close to/up to 11:1 cr. Especially if you go with aluminium heads.
A solid short block is always a good idea, but if your crank, flywheel, rods, etc etc are in good condition I wouldn´t bother converting to internal balance. Not for 350hp anyway.
