68chevykid it depends on what you want to do with your truck, if you lower your truck long tubes will drag on the ground. Short tubes won't depending on how you route your pipes, and most exhaust shops can do that for you if you don't have a pipe bender. Here is a link to 6=8 and some headers, there are other places out there. https://www.cliffordperformance.net/ Or Tom Langdon's stovebolt I opted for Tom's cast iron headers because they don't leak and make ticking noises. I included a pic of the headers and Clifford intake. Good luck with your choice...Vernski

Hi T.J. it's been about 6-7 years since I bought that seems like it was $160-$170 at Jegs, it may be a bit higher now though thanks...Vernski

68chevykid most headers long or short will fit, just quiz the seller about fitment they should know what fits what. Just be cautious I bought some long tubes from Summit, they fit after I made them fit. I had to move the clutch rod to one side to clear the long tubes, and Summit said they would bolt on. If you are going to lower your truck I would consider the short tubes because the long tubes will interfere with ground clearance even at stock height unless your building a Gasser or have a 4+4.
Do you have a link to that Langdon's will get in the way of the offerhauser intake? I would like to read that if you have it at hand thanx...Vernski

Slepysal,
Got them from clifford. Cool thing was that I paid the guy a visit while I was in california, so if you have any questions on what he sells( you name it I saw it in my hands) I can give you an answer. He is a nice guy, just dont get scammed by him.

Re: Tricked-out Chevy six cylinder engines

Here's my '65 C10 with a Six!

Started out with a 292 with Camaro 5 speed.

Just swapping over to this GM Six. Twin Cam, 24 Valves, VVT, and Fuel Injected. A little more modern. Expecting 300Hp before mods.

ok my truck is lowered and at some point will be lower than it is now,
i dont have the link but it was on this site that i read that. but they said that the flanges where it bolts to the head were too big, if that makes sense. so they say just trim the flanges down length wise. anyone hear that or is it true?

Yes. You are correct. Alittle grinding around the edges. No big deal.

Re: Tricked-out Chevy six cylinder engines

Its more the top surfaces matching. The surfaces are not the same thickness and the washer gets cocked.

Re: Tricked-out Chevy six cylinder engines

I definately agree with you. My clifford intake has a slightly bigger flange than my clifford headers. You have to out quite a kink in those washer I'll say!

Since you are lowering your truck you will definately want short tube headers, like the ones from clifford or the ones from Tom Langdon @ stovebolt.

sixtyeightchevykid,
The offenhauser intake will not get in the way of Lagndon's cast iron headers. Nor will the clifford intake( which is way bigger).

Glad it sparked your interest. It's not for anyone with a weak heart!

I stumbled upon this engine while combing ebay for chevy 6 cylinder parts. A twin cam 4 valve per cylinder popped up. I thought that's a mistake!

It wasn't. for the price of a 292 intake and carb, I purchased the whole 2005 engine off of craigslist. Complete with accessories and wiring. (2006-2009 appear to be the best years.)

I've been gathering parts and information for over a year. We just started fabrication a couple of months ago. We've placed the engine and 5 speed trans in the truck to make up the front motor mounts and sized up the trans mount location. And that was the easy part!

The oil pan needs to be converted to rear sump. We've had the radiator inlet and outlet swapped side for side. (the water intake is through the thermostat on the drivers side of the block) Since no one makes a header we're going to make our own. There are quite a few transmission options available even though the bell housing pattern is different that the 60's stuff. I've gone with a manual 5 speed from a Colorado pick up.

Almost everything you'll want to know is happening on the Vortec 4200 forum, http://vortec4200.com/forum1/index.php

A few turbo applications and a few stock engine swaps are in the project section.

I've received help and guidance in reprogramming engine control unit and wiring, purchased a flywheel and manifold flanges, learned about converting the oil pan, etc. A few guys are making up parts to sell and help move things forward.

Take a look. It's like the V8 guys moving up to the LS series motors.

Here's a shot of my truck, one with the 292 and another of the 4.2L.

Re: Tricked-out Chevy six cylinder engines

Thanks for the reply Riverside Racer

There was someone else talking about a 4200 I6 a while back. I can't remember who it was though.
