what do y'all think

[chefcraig]

is it worth the effert to swab out the 305 TPI and 5-speed trany out of my 87 IROC and drop in a LS1 and 6-speed out of a 99 camaro. I cant make up my mind what do you guys think? How hard is this swap? as far a fuel lines go what type of mods will I have to do.

it can be done, it will just cost some. be better to just save some cash and get an ss or z 28. just my thought. i have an 87 monte ss aero coupe that i was thinking the same thing. but it will cost over 3 k at the least. that's why i say just save some money and for 8-10 k you can get what you really want. thanks jeremy

too much bullshit you'll have to deal with, just buy a ls1 fbod

Difficult & Expensive, probably better off going with '98-'02 F-Car, However, if you are determined it can be done.

Primary issues:
K-member interference
Motor mounts
Fuel delivery
Transmission Bell housing is different bolt pattern
ECM, Wiring harness, & Sensors
Header Clearance
