1970 6cyl performance mods?

Long story short, my dad got wide tires in the rear and now everyone wants to race him, and he wants to beat them. Problem is, it's 6-cylinder. I realize that this car is rare, but there has got to be some bolt on performance modifications that will give this old Mav a little fire in her pants.

The engine is somewhat new. I think that it only has about 25K on it, and it seems to be running strong.

Thing we are looking for:
Performance head, or custom porting?
Manufactured performance cam?
What brand of valve springs?
Header
K&N filter, or custom cold air intake relocation?
He has the grabber hood and I was thinking that maybe drilling out the fake vents with some under hood fab work would be cool to draw in cold air.
Traction control on a mav?
Shifter (stock is 3 on the tree)
fuel pump?
How much gain from elctronic water pump and rad fan?
Anything short of V-8 install would be much aprecitated.

 

Clifford 6 into 8

These guys sell headers, cams and such. I also understand that the (250 if that's what we are talking about) 1978 heads have a larger intake manifold as well as valves.

 

Re: Clifford 6 into 8

Clifford 6 into 8 is the company? Sorry, I am pretty new to domestic performance brand names. I'll do a search to figure it out, but if you have a direct link, that would be great too.

Thanks

 

Yes sorry

That's the company name

Thanks JC and Charlie!

 

Wow... i had the same idea with my straight six... but at those prices i'll just plug in the V-8 later.... Fuzz

 

Does anyone have any good links to pictures of modded out six cylinders?

Pretty cool. There's something wrong with the redirect on that site, but I was able to stop it in time to check it out.

145 RWHP, a little less than what I thought it would produce with all those mods. The 15 sec 1/4 mile was impressive for an old 6. I doubt my dad could swing that with the 3 on the tree shifter.

The head sounds like an early Briggs & Straton with the wedge design.

The EFI crossfire sounds pretty cool.I dig seeing the intake manifold and huge plenum. Anyone build a custom intake manifold in the US for the 250? Weld a few injector bungs, slap on a TSP, bolt on a haltech and coils and hello fuel injection. Sounds so easy but so hard.

What is the compression ratio for a stock 250?
9.5:1? 10:1?
If you go EFI, how about a turbo charger, or super charger?
How cool would it be to see a Mav with a big ass intercooler behind the grill.

Think of the heads that would turn when you finish your burnout an people hear a turbo spool down through the tail pipe. Or better yet, the scream of a BOV after each shift. I could see mid 13s easy.

Dreaming...

 

oh

That link had some other links at the bottom. For a long time I thought about keeping my 250 and spent a lot of time on this fourm. These guys really know their stuff.

Ok spooledUP I know this is what you really want to do-

All I know about the car is in this quote. But it sure looks sweet.

Very cool stuff. I'm not so sure about the carb with a turbo, but there is no doubt that the power has be significantly increased.

I'm ready to hit the junkyard for turbo volvos and subarus.

I asol like the crossfire adaptation to the US250.

 

go to http://fordsix.com and hit the link to the forums. There's plenty of six cylinder advice there.

The Aussie Crossflow Mustang is mine. That's a pretty old page and the car is a little quicker than that now, running mid to low 14's pretty consistently while still getting 22-23mpg around town.



I have plans to replace that engine with a later model 4.0 OHC Tickford if I can find one at the right price. Tickford is the Aussie equivalent of SVT and their engines really scream.

I gotta tell you though, the turbo might be cheaper to do than an Aussie engine.

 

I'm not familiar with carbureted turbo setups, but I can see the cost advantage over EFI. I would think that you would get more control, and higher output from an EFI setup but of course at a steeper price.
How much output can the bottom end of an IL6 take?
Is there a big difference between the 200 and the 250 in strength? Is it just bore, or both stroke and bore which makes the 250 larger? How much can the 200 be bored out to?
Oh yeah, I found out that my dad has a 200 and not the 250. Why he installed a 200 and not the 250 when put in a new motor I do not know.

I am really hooked on the Turbo idea. Anyone have any more dyno charts on turbo mavs?
