I have an 87' IROC withthe305 5spd in it. Im looking for tips on what it would take to swap it withtheLS7 and T56 tranny. Is this possible, and what would i need to know upon undertakeing this project?? I would also like to restore the seats and interior in general in the car, any info. on places to check out would be appreciated.

its possible, bolting it in wont be hard, but i couldnt even begin to tell you what to do with the computer system, its going to be a real task.

your going to need the entire wiring harness for the engine or a retro fit one, painless might be able to make you a direct fit harness if you call them.

$$$$$$$$, thats what itll take. hell, id be happy with an ls1 swap. But an ls7 powered anything would be hella cool! Im sure gm would sell you the ecu, wiring harness,diagrams, and engine and tranny, just figuring out what someone has never done as far as i know is going to be the hard part.

Don't do it. It's not worth the dollars or manpower.

Me? Discourage him? Nooo way. I think a 500 hp 3rd Gen would be awesome!

schulzy100, There are a couple of sources for engine and Camaro parts. Summit Racing Equipment and Classic Industries magazines. 500 hp crate engines are about $6,000-$8,000. Classic Industries can mail you a Camaro specific magazine. Lots of fun stuff for the entire car. A literal toy box and wish list for any generation Camaro.

If money's not a factor the sky's the limit. Are you getting the 427 eng. and tranny at a reasonable price? Will you receive the computers and other necessary mods with the engine? If money is an objectdo you have the means and time to build your own 500 hp small block?

Please keep us posted. If you succeed in a 500 hp 3rd Gen please post photos and video of your new beast.

All the best!
