It will be N/a and street car , am wondering if there is diffrence between crankshafts 24 and 58 tooth which crank shaft will fit with ls7 , my car is ss 2001 , i think 58 will not work with my ss so that i will go with 24 tooth but i dont know if it will fit with ls7 or am wrong
i think the LS7 had a 'small snout' crank for the dry sump oiling system...either way if your going 4.125 or 4.250 stroke your getting a new crank...also...youll be running a fbody oil pan...and with a 2001, probably want to run the 24 tooth reluctor on the crank...so...basically a (whatever) stroke crank for ls1 (24x)....
hm...only thing i see is maybe the double roller, oil pump, cover...not sure...i dont run a double...just got the IWIS c5r chain...
look into what double rollers work with what pumps, some pumps need spaced, some covers need clearanced...

The standard len. on the L7 sleeve is 5.8 you just can't go over 4.130 bore. Same len. as ERL. and by the way the 24 tooth old style cr. wh. is for older model PCM and 58 tooth crank wh. is for newer PCM.

The LS1 accessories work as long as you get the snout correct. The LS7 has a longer snout to drive the "dry sump" pump, but you will want to order a shorter LS1 style to use the LS1 accessories without any kind of spacers, etc.
Since the LS7 block is meant for a dry sump, the casting at the bottom will need to be drilled for a dipstick for the wet sump. You may want to leave that up to a professional. The knock sensors and cam position sensors are in different locations as well, so you will need the harness extensions for them.
