Seems like the Google reviews for almost all rebuilders have someone not pleased with a warranty issue. There are BB ratings also. I appreciate zohan's comment. Stay tuned ownTer, I'll be posting results. If your willing 78Z, what kind of build did you do and for what $'s? Was this for your Z?

Yeh, Comic I'm also looking to replace my side mirrors. What are your please?

roadsterized/sbc conversion '74 260z. 305 sbc being replaced with 350

Just happens the GM Mr. Goodwrench crate engines are only 5000 k engines and power/tq. peaks pretty early. Again, not what I'm looking for ..... only in answer to your initial response "I'd just go with a gm goodwrench crate motor". So while I appreciate the comments, what I was really looking for was information on Reman. experience. I don't happen to have the facilities to do my own engine build, meaning I'd have to have a shop mill, grind etc.and by the time I finished researching parts combo's and paying for outside labor my best option is a good builder.

Yeh, I explored that option. Has many advantages, however, did'nt get me where I want to go. I'm going for a black block, chrome v/tc covers & pan. I'm looking for around 6000 rpm red line. The 3 yr. warranty is nice, but the hp/tq/rpm parameters and visual details just don't fit my check list. Last winter I replaced the 4spd Saginaw with a 5spd Tremec that give me the rev range I want for hwy cruising .... with the 4 spd. and rear in the car engine was doing 4 k at 75 and on a 5200 rpm engine not so good. Anyway, thanks for the thought.

Hi all. I'm going to replace the 305 SBC in my '74 260 with a 350 SBC. I'm about to order a build from MOTOR WORKS engines in Spokane, WA. Looking to see if anyone has any knowledge of them or Performance Clinic, Proformance or ATK. Just looking for any feed back before I order this out. My Z is a roadster conversion with a '79 305 using LT-1 heads, Wieand 8125 intake, Edelbrock 650 cfm carb and OEM cast headers from an early Z28. Valve seals are starting to leak a little, so instead of redoing this engine, eventhough it runs very well, I'd rather replace it with a 350-355. I've researched and talked with a number of remanufacturers and I'm about to let a build order out. Just thought I'd troll for any experience anyone might have had with MOTOR WORKS engines (Spokane, WA), Performance Clinic, Proformance or ATK. I have had very good feedback from MOTOR WORKS and like the detail knowledge and specific questions the've asked as to the specific application, use and spec. parameters I want. We've come up with a build specific to my likes. Anyone have something I might be able to use in terms of reman. companies (good/BAD)? I'd appreciate comments. ct240z
