Mind blowing indeed...

Here's a build-up of a 1000hp inline Chevy six

The OHC Pontiac was an awesome piece. They were strong and powerful and got good mileage. A little ahead of their time in the US market though. There's still a pretty good supply of them out there.

A company named Primatech Motorsports was building a 4 valve twin OHC based on two LQ1 3.4 litre Chevy V-6 heads welded together and I believe they were also working on one designed with two Quad-4 heads with 1 cylinder removed from each and then welded together. They had cams, stroker kits, custom intakes and superchargers designed. I don't know what happened with all that, their website is dead but they had some cool stuff going on. Then again, there has always been cool stuff going on by gear heads with cash and sometimes even cooler things by gear heads with no cash!

Yep..the Aussie 235 Hemi-6 was quite the engine. One HP version had 305hp stock!

Hemi heads, but the spark plugs went into the side of the head rather than down through the center.



Here's one for you. Dick Landy's Ball & Stud 426 Hemi...

Saw this engine installed in one of Dick's Darts at Carlisle several years ago.

Ok...Went to a local car show this weekend. One of the many nice rides on display had the engine pictured. Not a whole lot were made, comparatively speaking, but they have a large and loyal following.
So....a sorta trivia question. What brand is it? Someone I'm sure will know, even with all the aftermarket goodies.

Buick??? Or Olds

Nope..not Buick or Olds.

It's an American Motors 390. It was hard to tell, but I think the owner was kinda proud.
Too bad AMC never made a van.

What was interesting is that the AMC 360 (no relation to Mopar's 360) was retained in the Grand Cherokees from 1987-1991 even after Chrysler took over. Strange ay?

There were two versions of the AMC 390, a short-deck and a tall-deck casting.

Not to change the subject. Just wanted to share this.
Speaking of inline Chevy sixes.....
I used to watch Cotton Perry run mod-eliminator back in the 70's with a Chevy six. Routinely turned 10,000+ rpms (the sound was amazing) and 10second ETs.
With a steel crank and seven mains they were very tough, valve springs and push rods were the weak point.

BTW....The show I was at Saturday had two AMXs and both were 390s. One was original but I couldn't get an engine pic.
