I have an aluminum LS 5.3 LM4. I just tore it down completely and flex honed the cylinders. It will be making its way down to the machine shop soon. I will be building it for a twin turbo setup.

I'm running a new 350 with a TPI that starts up instantly and is by far, the best running motor I've ever had in any of my Novas. I'm done with carbs and all their problems.

I had a 396 in my '71 Nova and now have a '63 with a small block. So far, I like the '63 better. It has the TCI 4 link and CPP minisubrame. Handles nice and the car is light compared to my '71.

Exclamation

I'm having a blast with the small junkyard LS stuff.

2010 5.3, DOD delete and 229/235 cam, 3800 stall TH350, ebay headers, and 3.73s in a 10 bolt. [email protected] Shifting at 7000 and drive it anywhere.

It runs as hard as a Dart head 383 I had years ago, although admittedly I've learned a lot about getting a car down the track since then.

That small block can't match the torque though. And a small block is going to need expensive aftermarket heads to do what a big block can do with factory castings.

Knocked back a 434 SB only to build a 489 BB... Hopefully one day in this lifetime when it's done I'll see what the fuss is all about...

No replacement for displacement, luckily the LS series is a stop gap. Going with a mild 5.3 and stock front. Have a the rad and CBR mid tubes. Pulling my SBC this October and installing the 5.3 fall of 2020.

Fuel injected 454. Too much torque for the tires. Will have to narrow the rear axle and put tubs in.

BBC vs. SBC

BBC all the way but not a MK IV, a MK I. Yes for those of you scratching your head the MK I is a 409, I am running a 475 stroker W motor with Hilborn mechanical fuel injection, makes 600 HP on pump gas with 10.5:1 compression. Its fun to watch people try to figure out what the hell is that, you can tell the younger generation guys from the older ones. The 409 is Chevrolets original Big Block and a version of it was Chevrolets first 427, the Z11! Nothing against SBC, they are great motors but they are like belly buttons, everybody has one. I also have a 67 Corvette with a 327 and I never open the hood because I feel like people don't want to see another SBC with a chrome air cleaner and aluminum rocker covers, sorry I know Ill take heat for that.
