'70s style engine questions.

[85_Ranger4x4]

CFI air cleaners actually have a bigger diameter hole but you're right, they won't fir on a carb. I use air cleaners off 2 barrel carbs on my Holleys.

I looked it back up, they call the CFI a 2bbl so that is where I got my wires crossed. CFI is 5-3/8" diameter hole, 2bbl and 4bbl carb has 5-1/8". It was 2 years ago I went thru all this...

What are the real differences in the dual snorkel air cleaners?

OK, I know the dual snorkel was used '82-'85, both 4v and CFI. I know each was slightly different. My question is; what is really different from one to another? I know some are different heights, etc., but which is correct for which application?

The jacked up rear end is also better for MPG, you are always going downhill, even when stopped

Oh, and forgot about the slapper bars.
Six cylinder springs and shocks on the front for weight transfer.
Small piece of vacuum hose slipped behind the points to prevent point bounce at high rpm.
Usually a much bigger carb than needed....
Hood scoop.

Nothing makes a car corner sloppier than extra long leaf spring shackles.
If you really want a tunnel ram you can find them at any swap meet, anyone who installs one for the looks takes it off because of the way it runs. Low intake charge velocity equals BOG.

I always liked the Offenhauser Dual port design Walt mentioned on the first page - I'd be looking for one to play with.

 

[19Walt93]

I found the dual port I used on the 2.8 at a swap meet in Amhearst,NH just by luck in the middle of the project, I was planning to keep the 2150 on it. There was a guy who always had a big display of intakes and carbs for sale and it was sitting on his table for $150 marked "2.8 Chevy".I told him what it really was and took it home for $125. Offenhauser manifolds are actually single planes with a divider down the center of the plenum but they cat like a dual plane on a 2.8 because of the firing order- #1(rt side)-4(Lt side)-2(R)-5(L)-3(R)-6(L). I also used a dual port on my 351 for the Ranger, I bought it at Carlisle with a carb and spacer for $125 and thought I'd hit a home run. When I got it home and took the 4160 Holley off,I found out that it was a spread bore manifold with a square bore adapter and carb sitting on it. I bought an adapter to use instead of a spacer and it's on the truck.

Thanks for all the replies. Now I really can't wait for all the swap meets to start back. I would like a set of traction bars but they're expensive. If anyone has an old set for an '87 Ranger cheap I'd be interested. My truck is pretty new by my standards but I like to be different. I already have skinny and wide tires on it and it has the rake of shackles since I'm still using the 4-cylinder front suspension. And I can't have a '70s vibe and feel without the toploader 4-speed of course.

That was another "trick" for street drag racing; using 6 or 4 cylinder springs and shocks on the front...for weight transfer. Not sure how good it worked.

 

[19Walt93]

Light springs on the front helped some launching on the drag strip but were treacherous on the street, especially on a bumpy corner. You can drop the front by cutting a coil off a heavy spring. The only way to preserve the camber angles is to use dropped I beams. Extended spring shackles were common for a while and hurt the handling on every vehicle. They would make a late 60's Mustang corner like it had 2 really soft rear tires. If you absolutely have to raise the rear( and I don't know why you would),please add spring leaves or use blocks instead of long shackles. I prefer a safe and functional vehicle to one that causes oohs and aahs at a car show.

I'm old and was around for the 70's. Open element air cleaner as shown on page 1 like the old HiPo 289's had. Also an Accel Super Coil and their yellow plug wires.
