3/4 or full lenght headers for 351W in a '66?

Post by luckystiff »

We have a customers truck in the shop for engine refresh and dress up. looking for header options for it. pretty much no one offers a direct fit for 351w in a '66 that I've found. general response is anything for a 65-76 with 351w will work but not really much listed for that either.

several options for 302 but not 351 and from what I've found the deck height difference kills any 3/4 or full length 302 options. I know mustang shorties will work but we'd really love to find 3/4 or full lengths if at all possible.

I talked to Stan's Headers last Friday and his engine swap block hugger 3/4 MAY work but it's a $600 gamble set.

Just wondering if anyone had crossed this bridge and solved it....Ken....

There is a lot of generalities there as to engine mounts and positioning. I go by trial and error, borrowing headers if I don't have any acceptable candidates. I have successfully used the '80/96 Bronco applications with no problem, but, I am sure there are variations brand to brand, and I have no idea what brand(s) I may have utilized
I'm sure we have members with your exact configuration who will weigh in; again it may prove dependent on engine positioning.

they are what I believe to be stock mounts for a 302 in the '66. wasn't '66 the first year you "could" get these trucks with 302 from the factory?

you are the second to mention bronco app units.

I've read LOTS of what will and won't and most are contradicting to the next post you read at best. I personally think full or 3/4 are nearly a waste as it's going to retain the 3 on the tree. my experience has usually been fulls help top end power more and can sometimes hurt low end.

I had found him a low mile 302/aod donor and he wanted to stay 3spd. seems several problems would have been easier and performance better with the 302/aod combo as I've seen much more positive feedback on long tube for 302 aps...Ken....

I am not aware of a Windsor of any form being offered for the '66's and the 302 wasn't in production at that time. It's an easy swap utilizing the later mounts, but as an example, my neighbor has re-positioned his 302 twice, both times with factory hardware from my information.

Sanderson headers makes a set of headers for 63 and up f100s for 289-351w engines. The part number is FF2. These are a shorty style headers. I talked to the people at Sanderson and they said these would fit our application ,I have the same combination, the price is $300 for plain steel or $470 for ceramic coated. I hope this helps.

Just looked up the FF2's; it looks as if people have fitted them on everything from mid-30's ford chassis right on up. They are probably a good choice if a mid-length will meet the customer's desires.

Yeah the FF2 was always a back up as we are a Sanderson dealer. The FF2 is on that same list of possibles that I've heard mixed fitment feedback on. probably where we'll end up going unless the customer wants to put down the money to try the Stans new engine swap set that he thought would fit. nice but a coupla hundred more than the sanderson...ken...

Yeah, there's people down here who were dis-satisfied with them. I don't recall the reasons, hopefully, they will weigh in on the matter.

I cant say for sure but I cant see any reason why a 1980s header wouldn't fit a 1960s truck, both use twin I beam setups. I hate long tube headers and would use shortys or 3/4 length

My :2cents: worth, long tube headers are great for higher RPM usages, but for a street cruiser, daily driver or chore truck that primarily operates in the range of off idle to 4500 RPMs, I would not hesitate to run shorty or 3/4 length headers. They will put less heat into your floorboards & lessen the potential of baking the life out of your starter. In fact, if I had some nice OEM cast-iron manifolds, I'd run them. The manifolds will not burn out in 2 to 3 years and do not tend to develop exhaust leaks at the cylinder head exhaust gaskets. Either way, I would still run the remaining exhaust system out with a smooth dual pipe/muffler package. I have a pair of DynoMax Super Turbos on my F250 390" run out and dump kinda under the taillights. I also like the performance/sound/longevity of the Magnaflow mufflers too. Cheapo turbos will get you by, but they aren't the same.

correction: steering box location is different between 79 down and 80 up which will probably make a newer header not fit.

i havent finished my truck, but our intentions are to use late model 302 mustang shorty headers. from our mock up they will clear. the only difference is that i changed my 64 f100 to mustang II front suspension but they should clear your factory steering box. hope this helps, eddie
