Question LS1 in '95 C/K??

I have a 350 powered 1995 Silverado with over 100,000 miles and it's time to get rid of that tired engine (200hp when new). I would like to drop in an LS1 for a fun driving vehicle. Anyone try this yet? Any suggestions?

It could be done, but an LT1 would be a much easier swap. Would pretty much bolt right in.

You might also want to check in over at LS1Truck.com. There are a few older trucks with LS1 transplants.

I just did an LS1/4L60E (99 camaro Z28 325 horse) in a 1990 454SS. Pretty much a bolt in except accessory drive. We used a Street & Performance complete drive conversion. S & P Harness, G-body headers, & some other misc S & P parts. Needed longer driveshaft. Crossmember was simple mod. Even used the stock column shift linkage. The swap was pretty straight forward. Used stock Camaro oil pan. Stock 454 motor mounts with S & P plates.

This is not a plug for S & P, just who we contacted for parts. I wasn't thrilled with their cust svc, though. They always had parts backordered when we needed something. Prices are very high (in my opinion).

This truck went 14.51@94 mph in 1/4 on a 96 degree day. My own truck was 1/2 second slow on this day. I think with reprogramming 2-3 shift, & better temp it wil go high 13s.

This truck is driven everyday & is a blast to drive. It's got Baer 13.5" fr & 13" rr and Air Ride Technologies full kit.

Default stock tranny match up?

SixSpeedSS,
Could a stock 4L60-E from a 1995 C/K 1500 match up and work with the LS1 swap?

I just got done doing a 5.3 conversion in a 1994 4x4 chevy. All I really had to do was change motor mounts, and fuel pump, I should have had a redone harness instead of doing it my self but I will know for next time.
