Re: Budget 71 Chevelle build

I've decided to work on the wiring next, I'm installing an Aeromotive Stealth tank, PSI ls2 conversion harness, American Autowire classic update harness, and Dakota digital hdx gauges. I'm a little overwhelmed with the wiring. It will probally take me the rest of the summer to finish this part.

I went with the Holley Frostbite radiator for my swap, it's pretty and fits perfectly, but it's expensive for the quality. I'm going to use ford windstar fans as well.

Hello there, I came across your post. I purchased 71 chevelle malibu ss in 2011. I took the car apart and would like pointers on how to start to assemble my rolling chassis back together. I checked your updates of your pics, it looks awesome. Any input would be great. I'm in Los Angeles California.
Thank you,
Mel

I forgot about this thread but I've made alot of progress the last 18 months. I originally was going to run the stock ls2, but I fo uh HD skme damage in one cylinder when I took the heads off. I ended up building a forged ls3 instead. I also ditched the gto accessory drive and went with the new holley midmount drive.

I bought a new reproduction SS dash and I'm pretty pleased with the quality. I made a quick bracket for the power window switches to fill the radio hole. I need to find something to cover the other hole.

This is about where I am now, I have the vintage air installed where it'll be hidden with the fender installed. I used a 4 way bulkhead at the firewall but it would have been better to just run one long hose instead.

Re: Budget 71 Chevelle build

This is a wonderful build. I read budget but I see lots of money . I love those gauges. They have the same thing for the Cutlass... I'm sold. Sorry to hear about your engine. I'm currently prowling for an LS engine for my Cutlass and you had my worst nightmare - broken engine. I am fine with 5.3 and maybe iron is okay. If I do get a bad engine, I won't have spent as much.
Will you be perched a little high in the front after the "weight loss". I understand you will have shed at least 100 lbs with an LS3 over an SBC. My planned build will be the FiTech engine electronics and intake, Tanks Inc. (tank and pump), LS6 or better heads. I am hoping for 400 HP at the flywheel. Less than that would be okay. I am also planning on a T56.
Keep us updated!

I haven't updated this thread in awhile. Last year I had finally got the car running and roadworthy. I probably had about 40 miles on the car at this point and the engine dropped a valve. It turned out that the rocker arms that I bought was a Chinese knockoff of the OEM part and others have had the same failure that I had.

Luckily I was idling when it happened so the damage was minimal and the engine could be rebuilt.

While deciding what to do with my damaged engine I found a deal on an erl sleeved ls2 block with a forged 4" stroke crank.

For those that don't know these are alluminum blocks that have had the factory sleeves machined out and have had thicker, longer and stronger ductile iron sleeves pressed in.

The block also has pinned billet main caps and arp hardware on the mains.

The bore on this block is 4.155 and I still have can bore it .030 over in the future which is more than I can do in the factory block.

Here are the specs on my new engine, I'm aiming for 550rwhp/500 RWTQ.

4.155 bore ◊4" stroke 434 ci. 11.7 static compression
Compstar crank and rods
Wiesco flat top pistons
Johnson limited travel lifters
Advanced Induction 280cc 821 heads

I plan to break the engine in with the stock intake and the 1/34 headers I have already and later on switch to a tunnel ram intake and 2 inch headers.
