I'm intrigued by TSP's offset strokers. Sounds like a cost effective way to get more cubes. So what's the catch?
Is there any disadvantage to an offset stroker? Balance or Vibration issues or anything?

The smaller journal may wear faster, but hey maybe not, it's good enough for NASCAR!

I spoke to Trevor at TSP and Allan at Futrals who really know their way around these offset strokers and I will go that route in the future.I know TSP has been running good size shots of NOS thru the offset and cant seem to break the crank.

My understanding is if the crank is cut correct it has little impact on it's strength,time will tell.

You cant buy just the crank. They sell it with Carillo rods pistons, and bearings i believe for $2100. Someone correct me if im wrong

the downsided to this are basically just avaliability of the rods, and bearings. some go down to a 2.0 rod and bearing which is the same size as was used in some SBC's and some extreme cases the rod end goes to a 1.88" bearing size, and only carillo (to my knowledge) is making rods for them. the bearings become a bit harder to come by than just a trip down to napa. i very seriously considered doing this to my motor, and i'd still like to, but not w/o some extra parts just to have laying around. just my 2 cents.

I always think this sounds good until thinking of it this way...

$2100 for a offset ground stock crank with a 3.82 stroke that is worth ~19 CID, make a 346 into a ~365 or ~$110 per CID gained

vs

$3500 for a Lunati forged crank with a 4.00 stroke that's worth ~36 CID, make a 346 into a ~382 or $97 per CID gained

The offset crank would be pretty sweet with a big bore. One would already be in for the rods and pistons in that case, so whats a few more hundred for an offset ground crank?

I was thinking along those same lines. A 396 is just

4.08 bore x 3.82 offset ground crank equals (roughly) 400ci t/a
this would be the way id go if i went bigger cubes, if i werent poor

Good price break down for the $/cube but if you look at the net cost its $1400 less . I think thats what really matters.

Actually thats a set of patriot heads. Throw in another $1.5K for a cam and some full roller rockers and an intake (if you don't already have one) and you'll have a beast on your hands.

for 3500 you get the whole kit from lunati right...pistons and all
