Some Internal Questions
Some Internal Questions Just wondering...
A LQ4 6.0 Iorn Block
Will it support a 4.250 crankshaft?
Will I have clearance problems?
If it can, how many cubic inches will this make with a 4.040 piston?
Has anyone done this?

I can't see it clearing, and the rod length would be so short that side loading and pistons speed would be high. If you want more cubes go to a sleeved ls2 or wait for a warhawk block.
I was just looking for budget build... I WISH i could have a warhawk block I was looking at there website and it will support a 4.250 crank and thats where i got the idea... Just really looking for a budget super stroke LS1
Yeah, you would be better off as far as clearance is concerned with the 4.125" stroke. 4 1/4 is awful long, and the rods will surely make contact. I would go with a sleeved ls2 block, and call it a day IMO.
So what would be the diffrence in a sleeved LS2 and a LQ4 besides the Iorn v alum? I was thinking there the same except in the valley trey... one has knock enors and one has the deal for the DOD stuff

Verdad Gallardo The ls1 has less teeth. If you use that you need to get a ls1 reluctor wheel installed. It needs to be on there with a good deal of accuracy so make sure whatever shop does it knows what they are doing. The sleeved ls2 can go from a 4.100-4.155. An lq4 block goes from 4.000-4.060. To go 4.060 you really need to sonic test first to make sure the inner bores have enough metal to be bored out that much. It is most common to go 4.030 or 4.040 with an lq4. A 4.125 crank should clear fine, but I would stick with the 4" stroke to get a better rod ratio and stroke to bore ratio. Typically you want an equal bore and stroke, or a bigger bore than stroke. Balancing with a longer throw crank I have heard can get expensive also.
