I dont currently have a motor the car was a roller when i bought it! It seems the V6 cost a fair amount more to build but the flip side the LS would require allot more fab work which will ring the total up there i think along with many others though the LS will handle bigger power better than the 6 long term.

Well i have decided to go the LS route and give my fab skills the challenge of keeping A/C while still running a turbo should be fun! Now for the Ls guru's what is a good foundation to start with block wise for a turbo build i was looking at a lsx 454 block i would like to have a fairly large CI motor just dont know if that is the way or not? The build will be getting nice internals and matched for a turbo which i dont want to be a huge unit if posssible for clearance reasons so i am open to suggestions and direction Please!

Chris ,the other said he'll take the headers but if he back out I'll let you know. A 6.0 will make 1200 HP with turbo, you dont need to go with that big with a turbo. 6.0 is fairly cheap

I guess somewhere in the 850hp range i want something to get me in the 9's fairly easy but with some room to grow if needed later which is why i was thinking a larger CI and low amount of boost for now then turn it up down the road if that time comes just need to be sure the motor will take it!

I would be fine with building a forged 6.0 as long as it would be able to handle the power long term and maybe a bit more. I just like doing thing right the first go around and overkill it for good measure!

That is what i am hearing but i was figuring for a little more $$$ get the LSX block that is stronger plus has 6 head bolts might be overkill but if i decide to get a little crazy some day the foundation is there already. I think the biggest challenge will be the exhaust keeping the a/c but like anything it can be done!

Here is a question anyone here ever slapped a procharger on a Ls'd Gbody thinking that may be a way to help with the tight exhaust issue? Pro's and cons compared to a turbo system?

I know it would be a tight fit thats why i am considering other routes. i seen a thread about someone doing a procharger on a g body but i dont know if it ever happened.
What are the differences in the turbo compared to a supercharger? Spool differently?different power level? when does a supercharger need intercooled?

Well decided to close the stock A/C hole and smooth it out i will probably go with a vintage air system further down the road. I contacted BRP about their mounts and told them i plan on running a 4l80e and they said i would need to cut the trans tunnel to fit it! I know a few guys here running the same trans and dont think they had to cut to fit so i guess the mounts are different with engine placement. What mounts and pan should i use to have the 4l80e fit without cutting?
