I been throwing around quite a few ideas for the engine bay and was either gonna do a 6.0 swap or buy a 383 stroker kit and have the work done to my truck but figured it would run around $3000 for parts labor and to have the block bored and put together. I came across a website while shopping ebay and I found a company that sells short block 383's with a complete and balanced eagle rotating assembly for $1700. This seems to be a good deal, I just wanted some input from the gallery as far as the quality of the components used in this setup and if you think I would be able to run a properly tuned 150 shot or run moderate boost on this set up later down the road, around 8-10psi. I was thinking of going with 64cc heads with 10.9-1 CR. for NA performance http://cgi.ebay.com/ebaymotors/383-C...QQcmdZViewItem

 

A copmlete eagle forged rotating assembly will run you 2200. IMO I wouldnt mess with it cause they skimped on parts somewhere to get that price. Old saying goes you get what you pay for. It seems to have good parts in it but personally I would go with forged internals. 383 idea is nice though you could definately make some good power.

 

looks to me like a sbc 383 not a lsx build why its so cheap

 

Thats what I figured, I knew it would be about that much to buy the rotating assembly and then of course, the sonic test, bore, gasket kit, labor I want some quality parts, but was just wondering if this is just as strong as a stock gm bottom end, which is pretty strong, I know parish was running stock bottom end on his truck when it had the 6.0 and smaller turbo so I figure if it were atleast that strong, it would be good for atleast 500 rwhp. Your correct though, this price is way too cheap for the completed motor.

 

sbc? dont understand whats the difference?

 

That Is Just A 383 That Is Not Going To Work With Lsx Style Completely Different.

 

one is a 350 based motor, the other is an lsx, like the ls1, ls2, lq9 ect. basically old technology vs new stuff.

 

sbc=small block chevy that block looks like a genI block lsX motors are genIII blocks. lsX motors are the newer designed engine that first came out in the corvettes in 97 or 98 I believe i.e. teh 4.8, 5.3, 6.0, 5.7 and now there is the ls2 series engines that are even better. That would explain why the cost is so much cheaper than I would expect cause you can pretty much double your money to build an engine when its going to be a lsX motor over a traditional engine.

 

thats not a genIII. thats a small block 350 stroked to 383, not a 5.3L stroked to 383

 

Now I understand, thanks...back to the drawing board
