One thing I'd like to see more of is younger guys building Pontiac engines, not just using the Pontiac styling and swapping in modern drivetrains.
Dollar for dollar is if you're buying a "performance built" LS crate engine you're going to be north on 10K, especially when you factor in all the stuff needed for the swap, using a factory block you can get a well built Pontiac for about the same amount or less.
If you build it yourself you can use an aftermarket block and go all out.
MR1 block $3000
Aluminum roller heads $2800
Forged 467 Stroker Kit $2200
Roller cam, lifters, rockers, PR, etc. $1200
NW intake $350
Granted the other little things and machine work will add up, but you're now talking about a Pontiac 467 that will put out some serious horsepower, with Tq numbers the LS probably can't match.
If you're not going original appearance, seeing that under the hood of a Vintage Pontiac vs an LS
is what I want to see.
