anyone fitted one? Been advised to do my internals if I want to get best from new heads and cam and been pointed at Callies crank and rods with Je pistons. Figure might as well go to a 383 setup if I need to strip the block down anyway, just wondered if there was anyone else had done similar. Adding a fair bit to the cost so if anyone has cheap sources they can point me at :-)
Shoulnt need to do internals for heads and cam unless you need more valve clearance for the cam. Nowhere near as much pressure in there as supercharging. Guys cut the standard piston tops for valve clearance too so I wouldnt bother with doing internals on NA unless the old one is toast or you want to stroke it. My 2p.
Of course given the choice of a blueprinted engine or a stock one, blueprinted would be nicer, you can add in stuff like valve reliefs and more displacement. Question is do the benefits outweight the cost?

IMO, it would be cheaper ( well, probably not....but anyway ) to source a complete assembled short motor from the US.If you want 383, the block will require honing +0.005". This must be done with a deck plate in place. The LS liners are very thin, and this is as far as you can go, so it must be done correctly, and accurately.
I had mine honed by Dave at Performance Unlimited in York.
But...costs shipping to and from, costs to get it bored etc etc soon add up. With hindsight, I could have got a 402 from the US....for not much more money overall that building your own 383 might cost.
You could go for 382 which uses the standard bore size, but pistons arent as common, although its easy to get any of the custom made to suit a standard bore. And is what I did first time I went the stroker route..
With hindsight and what Ive been at recently, I would reccomend just buying a complete short motor. Most are a bloody bargain IMO, especially with the exchange rate etc..
And you may be able to sell off your standard short motor.
The only downside, if it is one, is that you wont have the original cars engine number. Not that its a big deal IMO.
Ive ran 346, 382, and now 383.
Id reccomend just going straight to a 402 LS2 based setup if you are considering a 383. At least with the 402, the next step isnt a dead end, should the need ever arise.
Good point..

Might as well make it a 416 these days Stevie

could you fit an LS7 ?
You could fit anything. But value for money is important.This one caught my attention the other day, although there are plenty of other offerings.

If it was boosted though, Id reccomend just heading straight for the 402. As I say, it leaves room for further re-bores should they be necessary, as well as leaving stronger thicker liners.
I just did dart 205cc heads and a mid range cam. Under $2000 US for the parts. Shipping VAT and fitting cost a fair bit.
Oh I also got new timing set and oil pump Fast90 intake and 90mm throttle. Add another $1800!
Ended up with 386rwhp which beat a few vxr500's on the dyno at vixpy's (Yes Island Boy I know my torque wasnt as good, but BHP was better)
Only 20bhp shy of Godzilla's C6 Z06 LS7 Corvette!
I also had otrcai intake and full exhaust setup.
Im planning similar for a vxr8 with TFS215 or AFR heads, cam and VE otrcai, aim this time is around 420rwhp and maybe even beat AM04R0's 12psi setup for bhp. ~550fwhp
I may do the TFS heads over the AFR for the extra valve clearance due to the altered valve angles.
Either way block will remain stock. If setup nicely NA will beat the low boost superchargers for BHP and fuel economy.. but not torque.. Higher boost, forget it NA wont do it unless you go crazy on the cam and make it undriveable on the street, uneconomic and terrible emissions.

I'll take a look at the blocks from the US lads and see how they compare price wise. Anyone shipped in a block from the US got any idea on carriage costs or best way to have it shipped?
The company going to sort out my heads reckoned I should take the easy option and bolt on a supercharger. Told him I wanted to do it a bit differently so he's going to flow the heads and choose the cam to suit whatever package I decide to put together. He did suggest the callies crank and the je pistons though as he reckons the Eagle crank is made of chocolate or might as well be. Btw Richard did you notice FAST/Comp Cams have relaunched their intake as a 92mm with t/b to match - those 2mm are going to make such a lot of difference Does mean there are a lot of places doing the 90mm intake for around the 700US$ mark though so bargains to be had.

Still a damn sight cheaper than buying the bits over here though in my experience. Did find a nice set of stainless headers for under 400 quid yesterday, even if they are 409 grade stainless. Come with a 10 year guarantee as well so might give them a try, 4 into 1 with 3" outlet and 1 3/4" primaries.

Yeah I saw that. I paid $730 for mine about a year back off ebay.com I think they have done 92mm for marketing more than anything because weiland have an Oz designed intake that is supposed to kick arse at a cheaper price, probably only 90mm. Ill just keep the LS2 intake for a while until we see which is best. Of course I need to buy a vxr8 first Does mean there are a lot of places doing the 90mm intake for around the 700US$ mark though so bargains to be had.

Contact Steve at Moving Parts. he might be able to sort shipping for you.The company going to sort out my heads reckoned I should take the easy option and bolt on a supercharger.

The Eagle may not be as nice as the Callies.....but Im yet to break it ! And I have tried
Im using JE pistons now...which are nice. Still think next time around I want Wiseco's
In fact, if anyone manages to break a standard crank due to excess power, I'll be mighty impressed.

Might well be wrong, but did I not read an article that said that Yank headers wont fit right hand drive cars due to the re-siting of the steering column/power steering pump? Would hate to see that you have wasted your money.

hi i have ran a 383,422 and now building a 427 stroker 383 based on a 5.7 block.422 based on a ls2 block and the 427 based on a ls3 block, the first two with eagle cranks with no problems (make sure you have it balanced as they do not come done) a good bottom end with good heads can make very good power i use cnc after market heads and steel rods forged pistons etc, my 383 made 528 bhp,530 ft lb the 422 did 558bhp,572 ft lb dont know about the new one yet but hoping for 600+. the first motors were on std intake and 1.75 4-1 headers, i agree with stevie the 402 is good value and has big potential. then theres the cam choice !!
