Zix, this is an excellent and thorough suggestion. Appreciate the reply.

I agree with that. Look around for a project car. Don't get in a big hurry, they are out there. Like I mentioned above, I picked my car up without an engine in it. I have less than $15k in my car as it sits, including all mods. Making approx 460 hp at the crank according to a Mustang dyno. Oh, and the odo just went over 13k original miles. Car is still like new.

I think you should tell us what YOU want. If you are set on a LS1, it can be done. It will cost 10k min for the swap IMHO. Will this car need to go through emissions? Daily driver? Smooth idle? What are you using it for and how much of the work can you do yourself? These factors will play heavy on how to build the engine. Also Zix's price of around 8K for a engine is probably average and agree that the combo suggested would be nice. Don't forget about all the small things. Exhaust/custom chip/TB/clutch and alittle left over for new back tires.. Good luck!!!

Has any body used these guys? http://www.nu-tekmotorsports.com/product1.htm
They seem to offer some nice engines or short blocks for a reasonable price.

This is something I have been considering because the heads I have on my LT4 are too good to get rid of at this point. So one idea was to have them changed to a normal-flowing head and bolt them to the 427 from World Castings.

OK, I have heard of changing the heads, I thought there was a new block out. Is welding up the heads for standard colling a big deal? What about the computer, does it affect it at all, I guess not, since it would have to be reprogramed anyway? So this block will mate up to our engine mounts, transmition, intake, etc. with no problems?

My .02 after just going through a 383 renovation.

Go straight to a C5, pick one up for about $20k, save another $5k, bolt on a magnacharger and your at the power levels you want and you're starting with a much better platform.

They are more expensive (on average 10 thousand I figure for comparable condition - I think I'd rather have my engine mods done for the difference but that is why I'm asking all of you) and I don't like the look as much. My initial thinking with the LS6 swap is that I would add significant performance without extensive modification, a crate LS6 is around 7 grand on some sites I've visited. It would have good driveability and efficiency. It would start with great performance with significant room for improvement. If I kept the LT1 in storage I could swap out the LS6 and put it in a used C6 years down the road if I invest in modifications along the way. There is no longer smog testing here in Minnesota so I don't think that would be a consideration. A few people have mentioned supercharging and I am somewhat wary of this option from reliability and interior noise standpoints but don't no if that is warranted. Thanks

Having the heads changed over is pretty simple, should only cost about $200-300 to have a compenent shop do it. The stock computer should be able to handle things, I think you'll need to fab up a crank trigger location, but I have to double check on that...that might have just been for the FAST computer system and not the stock one. Other than that, yes, it should bolt right in to you existing engine mounts. Check out www.worldcastings.com for all the info on their blocks. They don't have procong, but the 427 short block is about $4800 if I remember right.
