No way I would go iron if your block is good. Just get some new rods, pistons, bearings, and what not and rebuild what you have. I would use stock crank as the stroker crank nearly doubles the cost of parts. Put the money you would have spent on a crank towards your new heads and get something good.

Agreed, only reason I went iron is due to me going turbo

i would like to get nicer heads but i think ls6 heads are going to be the only thing in my price range right now, will those work well with 383 set up?

Also will be getting a cam. i want something with a good lope to it but not to crazy, seeing it will be a street car.

It is to a point. I was looking for reliability and longevity is which why I went iron. I didn't wantthe block to be a weak point.

I would think they would be fine and can be sent out to be ported or sold for a nice set of truckflows or ages.. I'm not a fan of 383s so I really never looked into the combos those guys run

if the stock crank checks out ok i might just stick with it and get the rod pistons. just really looking into my options right now.

i think i found the cam i want tho, seems to have decent ratings. http://www.tickperformance.com/tick-...1-ls6-engines/

My point was you will make more power with good heads/cam on a 347 than a 383 with stock 243s and a cam.

Stock 243s aren't a huge gain anyway relative to their ~$400 price tag

Yep. If budget is a serious concern and the crank checks out; I would do some nice rods and pistons, ARP rod bolts, AFR/TFS/etc head, cam, FAST 102, and some 1 7/8 longtubes. Go have fun.


Budget and boost should never appear in the same stream of thought. Things get expensive fast.

True but you could also look at it this way, with a 383 and stock 243's there would be more room to grow. Down the road the heads could either be sent off to be ported or be resold for about the same price they were bought for and replaced with some aftermarket castings. It would be best for the OP to decide what he wants in the in the long run.

^^ How I'd look at things. A lot easier to swap heads down the road instead of being basically stuck with a 347. With a 383 you can grow into it pretty easily.

Or buy a 5.3 for 300 bucks put in there and use all that other money towards a Turbo kit..

It's all in what you want OP. You will get a million different answers.

5.3 shortblock $200
Diamond -2cc 3.905 pistons $300
Compstar 6.125 rods $500
Gasket kit $150-200 can't remember exactly
Katech Rod bolts 200
Melling oil pump $100
Ls2 chain $40
Cam $75

And all the machining work is still being quoted.
And you are going get the assembly balanced add $ 150 - 200 Those rods have ARP bolts with them do they not , you really feel like you need the Katech ?
