Hi, I'm building a 383 and need the bottom end done and need help finding a kit that includes a 400 crank, dished pistons, piston rings, rods, and bearings for under $800. I will be happy making anywhere between 400-450hp at the crank. Any help will be much appreciated! I'm kind of a novice, this is my first engine build and really excited to get started!

Also if you have any ideas of any Heads/ cam combo kit I could use that info too. Thanks!

That's about what I paid for my stroker kit on sale in 1999.

Good Luck

Don't forget it has to be balanced either internally or externally, which uses a specific damper and flexplate/flywheel.

What's your budget for the heads?

Thanks, dang I forgot about balancing it...
For a good set of heads I understand it will be spending about $1500 and then a little more than that to get a cam to go with it. I've heard a lot of good things about the AFR aluminum heads but I don't know what cam would work well with them.

Oh and my block is a 4 bolt, 2 piece rear main.

this company sells a pretty complete kit.   i dont know what bore size you have.   you'll have to look through the kits.   but theyre close to your budget.

I'd personally go with the AFR 190s.

What is the intended use of the vehicle?

all street

mostly street some track

mostly track some street

track only

mud truck

look good at shows...this is not the correct answer as 305s & 307s can be dressed pretty, lipstick on a pig Grin

That website is going to come in handy, thanks for showing me that! I thought forged internals were expensive? I don't see how they sell all that for that price. I'm either putting the engine in a 95 and up 240sx or an early model Silverado/ C10. Probably gonna be mostly street some track. A 240 will be more work but it will be worth it in the end.

Read the descriptions closely. The pistons are forged. I looked at several of the kits one that page and they all list the crank as nodular cast steel, there is a difference. Just be sure of what you are getting before laying out the cash.

yea, they're kits are fair priced, balanced and forged pistons.    as Scott pointed out, the crank is the weak link.    at least its not an eagle crank, ive seen and heard bad things about the eagle cast cranks.    ive heard the rods are pro-comps, {chinnese},?     but hey, its a budget kit.

Good call. I'm not going to be doing any kind of forced induction so I think one of those kits will suffice.

My crank is cast. I never planned to race it or boost it and I haven't had any problems. I keep it under 6500rpm too.

I think you'll be fine as long as you understand the limits of the parts you buy and don't try to make it do something it wasn't designed for.

The Datsun is a much lighter vehicle than the PU truck and will give much better performance. It will be like night and day over the original motor.
A cast crank will work just fine if you don't go to crazy. A friend of mine was running a cast crank in a SB with lots of juice and it hung in there amazingly well. He got his El Camino all the way into the high 5s in the 1/8th with it.

Hi there,
If you intend to go over 5gs then balance the
motor otherwise the cast will be O.K.
 What block are you using with maybe 4 bolt mains??.
 Good luck...

I have used skip white rotating assemblies on several engines, and as said before, if your not going to spin it past 6000 you'll be okay. Their balanced rotating assemblies are spot on the balance. I took one to the shop and had it checked and it was on the money. The rods are scat, as is the crank, I have been to their facility in Kingsport, Tenn. They have such a large operation, they buy everything in large quanities and get discounts on the parts they sell. If you buy a individual set they will come in unmarked boxes. They do their own balancing and machining there in their shop.

The Dart SHP 400 I am building has one of their assemblies in it and I trust it.
