Which engine? They made a bunch of different straight sixes over the years. http://www.cliffordperformance.net/ is the main source for high performance straight six engines.

I have wanted to build a twin turbo 300 ci 6 cylinder engine for a long time. Throw it in a first gen mustang, falcon, or ranchero with shelby-esque suspension components.

I'm getting in this thread before somebody says, 'best way to get performance out of a straight six is to pull it and put in a 302.'

I've always liked these motors for some reason.

FTFY.

Ford straight 6 drag cars were pretty successful back in the 60s, and there are some pretty cool parts out there for them.

There's at least one instance of LS Chevy heads being cut up and put on on a Ford 300 block.

The small six family 144-170-200 and to some extent the 250 can be upgraded with an aftermarket or Australian cylinder head that gets rid of the horrible integrated intake design and 1bbl. I had one in a Zephyr (Fairmont) and it was reliable but nothing fun in its emission choked state.

Triple Carbs are another option that always looks awesome.

Thats cool!

The 300 in the late 80's/early 90's Ford trucks were pretty cool. PFI helped out a lot. I've driven 2 different 2wd standard cab short beds with 5-speeds and they were peppy as hell.

I wouldn't mind one lowered.

A inline 6 with a set of headers sounds like nothing else on the street.

I think some of those engines came with 7 bolt mains - nearly bulletproof.

Do it!!

of course ford doesn't love us with the I6. Why would they push such a wonderful engine on a country that insists that a v8 is the be all and end all of power?

Fixed that for you. While their parts are still OK, they seem to have fired their customer service department and seem to only ship newly ordered parts when they feel like it. Too bad as they had some really good parts - I have an old Clifford intake on my Dart that has been reworked for EFI. In the Mopar world, their place in making manifolds have been taken by Aussiespeed - looks like they've got some stuff for Fords too.

Seven bolt mains!!!

You must build Chevy engines

I think you mean seven main bearings.

Pretty much ever I6 since the 1960's has had seven main bearings. I think the second-gen chevy stovebolt was the last one to have four.

The Ford 240/300 family is a monster, the Chevy 292 is right behind it. Even the smaller Ford six can have potential.

Clifford is awfully proud of their products for what they are. You can usually find Offenhauser manifolds for the big Fords much cheaper on eBay. The later injected 300 exhaust manifolds are as close to headers as you will get from the factory.

Actually, I think the last domestic inline six with four main bearings is probably the Mopar slant six. There could be some weird British or French motor that kept four main bearings longer.

Really? I know that you can graft 2 Windsor heads together and it will work.

Change of plans. Big A$$ 70s Lincoln coupe with an LS headed twin turbo 300/6

To get to a central point of the original question, while I'm not going to suggest that you should do a V8 instead just "because V8", I would certainly not do the I6 just because it's free... Performance bits are going to be rarer and more expensive than the ubiquitous SBF parts. Given how much a junkyard 5.0 costs, I'm guessing bang for buck still goes to the V8.

Also, it's longer, so if you want to go around corners, I suspect that's going to negatively affect packaging of the mass, though I don't know for certain about relative weights... Wait, you said "drag", so maybe it's a non-issue (though weight forward still seems sub-optimal?)
