Trip Report: 2000 LS1 + 1970 GMC - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's been a long way to get to this point. (Links go to LivingWithStyle.com forums, my old threads there)

I really wish I could've taken more than three passes down the strip, but it was really horribly crowded, and in seven hours I only got those three runs. The green-highlighted entries are the best of the night; the far right column is my dad's '01 Z28, as we raced together in a bracket-race format. He redlighted, while I cut a decent light (0.101, not great but not bad) and ran EXACTLY my dial.

The truck drives like a dream. The lessened weight has freed the front end up a bit, and at least last night on the track, it hooks surprisingly well. 2.2 60' times aren't bad for a pickup. I cut three 14.40's on 30,000-mile-old Yokohama Avid S/Ts, while another guy in a 5.0 Foxbody on drag radials couldn't break 14.90. Power estimates from the 95MPH run and an estimated 4200lb weight as-ran put it at 315hp - which is just about perfect for an engine rated originally at 305hp, with a freer-flowing intake, exhaust, but an automatic and more weight / more air to push around.

I really, truly couldn't be happier with the end result right now. If you want to see even more photos, see http://salj.info/cmine/ and click on the LS1 swap album.

Don't know, I haven't calibrated the speedometer yet...or run through a full tank, for that matter!

Nice times, and your Rt is very respectable!

Thanks...it always takes me a few runs to get back into things but I've actually cut some darn good lights (under .100) in that truck. The 14.400 on a 14.40 dial was just great, but I had work the next day and I was falling asleep after going home after just that run anyway.

that is pretty cool,if you dont mind me asking-how much money is in a swap like that?

Smokin72on20s · 03-17-2005, 03:46 AM

sweet truck, that video link in the startup thread isnt working, i would really like to hear that thing run, also, do you have any side pics of your truck? i wsa hoping to see what that side exhaust looks like, nice work!

Project1970 · 03-17-2005, 11:14 AM

I could've sworn I replied to lloyd...did the database eat it?

Total cost into it will be about $8k.

Smokin: Let me see what I can do on the video, but my digital camera does NOT do the truck justice, and thank you for reminding me that I don't have any side pictures of it with the new exhaust yet!

Did you have to modify your oil pan at all?

I recently bought an LS1 and am going to install it when I get home from overseas in June.
