Indiana Z06

I'm having a 6.0L iron block 422 stroker built as we speak. I'm using Eagle rods, crank and Diamond pistons. For the heads, I'll be using the Trick Flow 235cc with Harland Sharp roller rockers. My SCR should be approximately 11/1. For the cam, I'm thinking of using the Texas Speed 248/254 .611/.613 114 LSA. I'm having to use an LS6 intake and LG Street Series headers for now. I know the intake and headers are holding me back but my wallet only goes so deep. I'm hoping for an easy 510 rwhp for starters. What do you guys think? Thanks!

Is it 4.030 bore / 4.125 stroke or do you have some odd combination? I don't think eagle makes a 4.125 crank only a 4.100 and 4.250 IIRC?

I know the block is being bored 60 over but I'm not sure what the crank size is. My builder has all of the specs.

Edit: I thought it was 60 over, but it's only 30.

i think a 4.06 " bore with a 4.1" crank is almost 425 cubes.
i think you are pretty close on your figuring of 510 rwhp or so. the ls6 will be a major restriction. a ported 90/90 setup should get you up around 550 rw or so imo.it should be a strong setup when you have all the right parts on there.

Here are some specs so far. Had to make some changes.

Bore: 6.0L iron block 4.030"
Crank: Eagle 4.125"
Rods: Eagle 6.20"
Injectors: 42lbs
Pistons: Diamond -7cc
Heads: TFS 235cc
Intake: Ported FAST
Headers: LG Street Series
Cam: G5X4

My rotating assembly is being balanced now. Hopefully, I'll have it running around the middle of August.

I like that setup mutch better than the above mention 4.06 bore. I want to build something like exactly like that, except solid roller.

Well, I finally have some results. With the 421 stroker, 11.2/1 SCR, TFS 235cc heads, G5X4 cam, FAST intake, ported 90mm TB and LG Street Series headers, we're making 498rwhp and 507rwtq. This is on a Mustang Dyno. I don't have any driving impressions yet but hopefully will by this weekend. We'll see what happens.

that is pretty good numbers for a mustang dyno,especially the torque.

I got a friend that has a 422 resleeved LS6 block and with 90/90 and AFR 225s, bigger cam and a great tuner he did 550rwhp and 505rwtq!

I have a simliar setup only with a solid roller and it makes peak power at 6200rpm. The ported FAST still isn't enough to keep up with the lower end.

Sounds like some good results. I still want to build a setup like this.

Great #'s. Glad to see more people are using this bore/stroke combo.
