So...How much does it cost to build a 380 cube ZR1?

I was thinking maybe we could "help the breed". The last 7 posts should have been handled differently, maybe "PM"????? I don't know or care if this against the forum rules, but I know it is very inconsiderate.

Woops! Sorry! Did not mean to get side tracked.
Tell you what - once my motor is out, disassembled and components get worked on, etc, etc, etc, I will share my experience of 380 build.

My apologies!

No - according to Ryan. I will still inspect the plug and make sure all is well before my mechanic starts closing up.
Hmmm, according to GC it's otherwise... I will look into it further.

And noted Redeye!
I will inspect the plug and turn to Dr. Phil for guidance.
Thanks.

Awesome info Hopefully Ill be treading down this path in the relatively near future.

What options are there for cams? are custom grinds available? Im tempted to want to do something like my LT4 build.. all lightweight, maxilite rods, hollow valves , solid roller etc.

Im thinking offset grind, longer rod, aggressive cams, hollow valves, solid lifter setup and rpm it a bit more for more hp. Not sure how the lifter setup is on the LT5. The s54 in my e46 M3 had a rocker setup that was easy to maintain lash with via swapping shims.

GC, Thanks

Does anybody have any Torque numbers from one of these?

No Problem! Was you planning on doing it over the winter?

I think SGC and Pete grinds Stage 1, 2 and 3(?). These are stock cams ground down on the opposite side of the lift lobe (?).
Now that I have more time due to delay I am seriously considering Stage 1, intake.

I think the question to ask yourself is , what power level do you want to get to? Again, you may be comparing apples to oranges looking towards the LT4 as a guide. Achievable power with few and simple mods to LT5 is rather impressive. No rockers in LT5, tappets directly actuated by cam lobes.

500+chp w just porting through to the heads, stock cams, headers and exhaust

550chp doable w stock displacement and bottom end. Add Pete cams.

Look at tpepmeir's 427 build for 700+chp and lots of choices in between and up to 441CID.
