I am curious for future plans if you are able to use any LS7 parts(i.e. intake manifold, heads, etc) on the LS1 platform, I am aware that the LS7 clutch and flywheel are compatible, but are there any engine parts that are compatible?

everything will fit as long as the LS1 block has been knocked out to a 4.1 bore or bigger. If not, then everything except for the top end.

As mentioned, with a 4.100" bore or larger, LS7 heads will bolt up, and since the heads bolt up, then obviously so do the intake, fuel rail, valves, springs, rockers, etc... The passenger side valve cover needs to be modified to clear the LS7 rockers. You need longer pushrods if using LS7 heads on an LS1/6 block, mine came out to 7.750" long.

i apologize for not being more clear i meant what parts would bolt up without doing internal work like what you guys have discussed, i guess i got my answer as in nothing will, just curious if i had any options thru bolt-on parts, guess not, i guess the clutch is it

i also was curious about this but more along the LS2 aspect of things.

I guess my question is about the ls2 heads and intake. are they better then ls6 parts? and wil the ls2 parts bolt up without modification like the way ls6 parts bolt up?

thx im a noob to the ls2 stuff

LS6 and LS2 heads are both 243 castings. The LS6 heads have lightweight valves though. and for the intakes, the LS6 is better, but the LS2 will bolt up.

Quick question. Will a stock LS7 intake fit a 2001 LS1, if so will I see any improvements? The reason I ask is because a friend of mine is selling me his LS7 intake really cheap, he is going to an alloy intake. Any help would be greatly appreciated.

no, you will need ls7 heads also, but thats not all, in order to use ls7 heads you would need more cubes. not worth it in my opinion unless you are gettin a bigger bore shortblock or something. hope that helped.
