Thanks for looking out for us lowly 326's! I too have no problems smokin' the tires. It also helps to have the M21 with 3.55 gears...

Without a numbers car, any engine is worth the effort to get it back to a Pontiac. If you were starting with just a core, I'd say go for a 400 or 455. A mild built 400 will cost less than a stock built 326. On the up side since everyone yanks out the 326, running blocks can be found for free!
