Freak I gotta bring you out to my buddy's place at Sheba Racing...he just finished dropping that motor in the same car. Ram air the whole works. 500 REAL horsepower...You would enjoy seeing his shop. He decorates his walls with fenders from all his Nascar crashes
I had a 67 grand sport for many years, rebuilt Buick 340 with a 2 speed powerglide....92 mph in FIRST gear. Man did that 4 barrel scream. I can still remember racing my buddy who had a 65 that we dropped a Pontiac 400 into with a Muncie 4 banger. He's beat me off the line but within 200' I'd smoke his ass the rest of the way down the strip

THEM were the days!
