LSA drive system for a 66 Chevelle

Hey everyone I'm currently building a 66 Chevelle 6.0 and a LSA supercharger, I've been looking at different drive systems and I know the stock LSA system has the alternator mounted on the lower left by the steering box. I've looked in LS Concepts race drive system has anyone else had any luck with a system besides having to buy LS7 for the left side and LSA for the right side. Thanks any information would be greatly appreciated

Maybe ICT Billet would have something ? They make alot of different kits.

I've seen theirs too, I don't think there is really any inexpensive way around it

Re: LSA drive system for a 66 Chevelle

I bought the ICT kit that moved the power steering in closer to the block and has the alternator in the "stockish" position. Would rather have the alternator on the pass side, which they make a kit for, but since this is my first swap thought the "chevelle" kit would be the place to start.

Mine is just a straight forward carb / nitrous deal so nothing like a blower / turbo deal...

Re: LSA drive system for a 66 Chevelle

Iíd be curious what you find. I have an iron block 6.0 and bought the LSX concepts alt/ps/ac brackets and plan to add an LSA blower along with their HD LSA drive in the future. At the time I was doing research this seemed like the way to go as far as ps pump fitment on our A bodies and overdrive blower pulley. Iím not too crazy about the idea of a fixed blower belt tensioner though.

NorCal SS I found this last night GM 19417908, it's a factory GM drive system for modified LSA application for older cars. It puts the alternator in the higher location and gives you all the tensioner pulleys that you need to get started minus the AC bracket which I'm going to get from Wayne at Kwik Performance once I'm ready. I know you'll need a LSA water pump to make this kit work. I agree I was looking at LS Concepts it's a nice looking kit but I'm in the same as far as fixed tension on the upper pulley at all times. My thing is if GM wanted a fixed tension all time they would have designed it that way
pannetron and NorCal-SS like this.

Re: LSA drive system for a 66 Chevelle

My E-Forced LS swap uses a similar GM FEAD except with the Corvette offset; it fits nicely. Dirty Dingo, among others, makes a mount for the Sanden SD7 A/C compressor that tucks it up close to the block, low on the passenger side. IMHO the GM FEAD makes the engine look more OEM, a look I like.

Re: LSA drive system for a 66 Chevelle

Just wanted to say thanks for posting the part number for the modified LSA FEAD from Chevrolet Performance. After some research it appears GM simply combined the Corvette alt+ps bracket with the LSA pulleys, tensioner and hardware to make the ďmodified LSA FEAD kitĒ.
I really like what this offers so Iíve started piecing it together since I already have Corvette alts and ps pumps. The individual brackets are actually inexpensive especially if you find them used and I like that they look factory. Holley offers a very similar alt/ps bracket that would work just the same. LSA water pump is required too, but I already had that.

It also looks like I should be able to use the Holley Sanden AC add on bracket in the Corvette position. This whole deal really seams like the most economical and effective way to get an LSA swap FEAD on these A bodies IMO. The Corvette ps pump can be pricey but if you buy the brackets separately you arenít forced to buy a new high dollar GM pump.

It looks like you're using the Sanden SD7B10 mini compressor, correct? How well does keep up on hot days at idle?

Re: LSA drive system for a 66 Chevelle

Agree. The GM kit seems like the easiest way. Unless your looking for the billet bling look. Here's my setup going in my 71.

Re: LSA drive system for a 66 Chevelle

Don, that looks good. I was wondering how the GM A/C kit would fit. What engine mounts are you using? Did you have to modify the cross member?

Re: LSA drive system for a 66 Chevelle

Don, also is the compressor fixed displacement or variable displacement?

LOL! While I have the compressor mounted, I still haven't installed any of the other A/C stuff! I'm an old, slow guy!

Sorry for not replying sooner. Using the Holley mounts, forward position, Holley trans crossmember, headers, oil pan. So the GM AC kit does not fit without modifying. It's pretty tight to the engine but the bracket hits the tie rod. I cut off the bracket and now has 3 bolts holding the compressor on instead of 4. Not sure if it will last but I'm willing to give it a try. Here's some pics.
