Yes going to maintenance day, not sure about Katie's, depends what time I roll out if the rack.

Ron,

I think the maintenance day is Sunday.

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

ok, thanks for the reminder. still think I can make it, but I need to check

like to work on the following items

headliner,
install new clutch mast cyl
tighten up the rear spindle bolts
look over installing the new cooling fans (but that will likely have to wait, might be more of a "do at home" project)

I really need to set up a pittsburgh zr-1 crew.

If you want door panel straightened out show up with plenty of crazy glue and a rubber glove (hate getting that stuff all over my fingers!). We got some glass mats.

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

will do! I will bring the new headliner tape and spray adhesive too

you are the man Yun! are you going to Kate's on Sat??

I got the "green light" for maintenance day

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

You know, I tried to make this a education thread, for people new to the ZR1, like me. I felt this might be a good way for someone who was considering building up their car, to give them a place to find answers about a build that would not be as expensive & bump up the torque numbers as a alternate to standard 500 hp 350. 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.

It happens all the time as folks tend to get off on a tangent. Its nothing personal.

I plan on getting my car dynoed this winter so we can see some numbers that everyone seems to have interest in. Right now its still 105 here in phoenix so.....

This is no sales job and the facts are plain and simple. If your going to go the 368 route anyway... without a doubt this is the biggest bang for the buck mod. Its like and additional $500. Do the math.

It will cost you time unless you have a lot of spare parts to shorten that process. This stroker will benefit from top end porting, head porting, headers and petes cams. I also suggest bigger cooling which I could discuss how I came to that conclusion as well. I also suggest Mark's Haibecks Cometic Head gaskets for obvious reasons.

I partnered with Dom and between me helping him pay for some of his dyno time he has more data on the 380 with Pete Cams setup than even the BIG GUYs have. A couple of us have done it now and its becoming a predictable platform. Mine a daily driver and it took almost a year to get the tune right.

This is a build that was carried on the backs of a lot of folks in this club. Dom, Jerry, Pete, Polo-1 (Kevin). Nobody in this community was talking about a 380 a scant year ago. It was 368, 415 or 441 with one exception Dennis's atomic Z which is a 396.

One last thing if you are going to go this route make sure the crank plugs are welded in if any offset milling/grinding is going to occur. This piece of advice alone will save you time, money and utter frustration when going forward with this project.

Now back to the build notes. GC

I'm getting ready to go the 380 route with an offset grind. Does the grinding process dislodge the plug in the crank??

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

IMHO yes. The crank has a blend of the screwed in type and the pressed in type. GC recommends welding at minimum the expansion (Press in) plugs. You are changing the dynamics beyond what was engineered. Same problem when you add major HP and dont add better cooling, better rear ends and better braking. Disaster.
