I'm thinking about a new crate motor for my 75SC (have 202,000 miles on the original 350)...I was looking at the GM Goodwrench 290 HP 350 because it's in my price range but then I found out that they're assembled in Mexico...Does anyone have any experience or horror stories about these motors?...I'd like to keep my car 100% made in the USA but don't want to spend a fortune...I'd appreciate some advice...thanks

I work for GM, most of the crates are made in Mexico or Canada, they are still reliable. GM does make sure they are in spec

My ZZ4 runs great!!! Had it for 3 weeks now.
Love it! Pass the chalupas, made in Mexico....schmexico, still runs like a chevy

GOT the goodwrench motor in my z and it runs great

I as well bought the gm350 about 3 years or so ago, had it in my 70 ran like a champ have a edelbrock performer intake,carb, and cam kit in it. Its been sitting now for about 2 years or so i got rid of my 70 due to all the work that it needed, but now i have a 71 that its going to go in.

BowHunter I hope that you see this post. Headman makes a "D" port shaped header and will fit the ZZ4 "D" port heads perfectly. I had the Supper Comps and I like the Headman best. I have modifid my ZZ4 and ran it on a dyno 420hp and 427Q

I had a zz3 in my 70 back in the day with some cheap Hooker Comps, they fit fine. I think they are the same heads, the plugs aren't at as much of an angle as other angle plug heads.

Yes hooker comps will bolt right up and work. However the ZZ4 does have a D shap exhaust port and Headman makes a good header that fits the ZZ4 and ZZ430 exhaust, infact they were made just for thoes kind of heads. not sure of the ZZ3 heads.

Anyone have any ideas where they ship the GM performance crate motors from ??

If its in PA, I need an exact city/location http://www.nastyz28.com/ubb/smile.gif

Hedman Hustlers, and they are cheaper than the Hookers.
