Strokers 383 or 396
Why are there not that many 396 strokers out there? If you are building a true stroker (instead of all-bore), why would you not do a 396 instead of a 383 (4" compared to 4.125"). The price seems to be the same. I realize with 409, the bore to stroke is getting a little out of hand.
I am looking at the possiblity of building a completely new engine this winter and I am leaning towards a 396 (stock bore + hone and 4.125" stroke). Do you think this is going to be too much stroke? I want to have two engines: one being a traditional H/C daily driver and the other being a more aggressive stroker with aggressive cam, but I would like to reuse the heads and maybe a few other parts. Would like to avoid stage III heads.
Any advise? I want to the monster torque from a stroker.

Going with a 4.125" crank, you will make lots of low end torque, but you rpms will drop like a rock. Plus a standard LSx block will need a lot of machining for cleanance. Plus you will have oil consumption problems of you do not use a shorter length rod. If you use a shorter rod, you do not get a rod/stroke ratio. Really just to many problems/issues for the extra 13 CI.

Do an all bore 4.125 block (388 with stock crank), with an offset ground crank for 396 ;)

After reading these responces. I am wondering , why not the 422 or 427 with the Dart enhancements? Damn I have dreamed of someday having that rumbling , Bad Boy 427 under my hood. One of these days, one of these days. :chevy

I woul dnot go with an offset ground crank. Several people over at the LS1tech forum have run into problems with the rear seal because of the rebalancing work. Plus you are making the main journals smaller. Just not worth it for an extra 8 CI.

Re: Strokers 383 or 396 (whiteboy)
422 or 427: I would love this setup, but I would have to do stage 3 heads, this would cause me to have two long blocks instead of 2 short blocks. Maybe I will price out a short block build. Would love a 427, now you have me thinking.......

Really? I've been on ls1tech since it started and I've never heard of anything like that before.

Re: Strokers 383 or 396 (kromberg)
Wasn't the offset ground stock cranks problems from the reluctor wheel coming apart from the crank?
I do agree that with a 6.2" rod and 4.125" stroke crank, you are running a VERY short piston with the wrist pin very far up in the piston which can cause it to rattle back and forth and cause more oil consumption.

Re: Strokers 383 or 396 (fast 98 C5)
To tell you the truth, I was on the MTI website and looked at the 427 Iron short block. The price is so attractive. Going to do some research, but I think I can live without the 85 lbs difference. The 427 badge on the side of a Corvette just looks awesome.
I am starting to lean towards an iron block + nitrous

I know that PSJ and Terry Burger have both changed from offset ground cranks because of problems.

Really? Hmph, I remember PSJ had the problem with the reluctor wheel, but he had an iron 422 at the time if I'm not mistaken, no offset ground crank.

Re: Strokers 383 or 396 (Mehfoud)
Thats exactly what I have. Made 484rwhp. My goal is to hit 500 (new intake manifold and electric water pump should do it).
I am eventually gonna go with a 436 when I can save up enough for a C5R block. I dont trust the resleeved blocks and the Darton technology is pretty new.
An all bore will make more peak power IMO but again, I am not comfortable with it yet.
With today's technology, I would be confident you could get a 436 motor to 530rwhp if you go all out.
