LT1 => LT4 conversion

That sounds essentially correct to me. I've been looking into this myself. You might want to look for the complete GM conversion package:

If you decide to do it, send me an email letting me know how it turned out!

BTW: does anyone know if a conversion like this is recommended in an LT1 with some miles on it? e.g. 140,000k? Or would it be wise to either get a complete LT4, newer LT1 or just "rebuild" mine before doing the conversion?

Thanks,

-Rob

I hate following up to my own posts, but, it's been well over a week since I asked the question. Surely, someone on this newsgroup knows the answer?

Thanks for the response. I couldn't remember if there was anything else. I wasn't sure about the main bearings and there isn't much I can do about that. I also wasn't aware that Chevy sold a kit for the conversion. I assumed I'd have to get the parts seperately. I'll have to check in to that. You wouldn't have a GM part number for the kit, would you??? It might be cheaper than buying the parts from other sources.

I agree that the bottom end shouldn't be a problem. Lots of folks are running Vortechs on the stock LT1 bottom without problems.

. Look under the "Featured Parts" section to : the right of the main page. There they have what they call the LT1 to LT4 : conversion kit. It includes the heads, intake, aluminum roller rockers, the : LT4 "Hot cam", and all the various gaskets and seals you need for the : conversion. All for $2100. The LT4 "hot cam" isn't smog legal in California, : if that is an issue for you. Sounds like a helluva deal to me! - Gary

Hmmm. I wonder why it wouldn't be smog legal in CA? They certainly sold LT4 Camaros and Vettes in CA.

$2100 DOES sound like a good deal for the whole package. Thanks for the tip.

This kit contains what is known as the "Hot Cam", which is sold over the counter only. The standard LT4 cam was a little milder. The "Hot Cam" was supposed to be good for another 30 hp over the standard LT4 cam. - Gary
