Please don't shoot me down to bad

I am going to put headers on my 390 while it is out

Which would be better long tube headers or shorty headers?


and wich would be the best for a 1969 F-100 truck?




Thanks

longtubes all the way!

 

ok longtube

why? would they give me more Hp then shorty?


what will clear a 390 in a truck?


what type of headers do you have kurt on you 390?

 

Depends, which headers you choose and which truck you have.

 

i have a 1969 F-100 with a 390 and a 4 speed

 

Street truck? Any towing planned? Any mods to the motor?

and ported heads

 

Any of the name brand headers is the way to go. Try here:

and you have to install the headers after the engine is in from under the truck go to www.summitracing.com i bought dynomax headers for 120.00 with shipping and come with all bolts and gaskets

 

Long tubes will be a bigger improvement, especially with ported heads. I ran into one header(Dynomax coated) issue with my '66 with MT. The clutch release fork hit the collector, I had to modify the fork(picture in gallery) to clear. You might not have that problem in your '69.

 

Sorry for the delay, memorial day obligations.

Anyway, on my '70 F100 I have Hedman headers. They work ok. If I had it to do again however, I'd spend the extra $$$ and get the ceramic coated units.

 

My 73' F250 w/390 the headman headers went in bolted up to the engine. It was tight and would have been easier with help, but I got them in by myself with out to much hassle. I also had the bellhousing and starter mounted up.

Jordan you are going to make me cry. I want my 390 back running so bad but soon it will be

Kurt and to everyone i hope that you all had a good holiday.


Kurt why would you get the ceramic coated?

 

Yep Nice Truck there Jordan....Nice looking Build going in it..I like the Coronet sitting in there too.. I have just the 440 in my old Motorhome to go in that!!

The coated headers retain heat in the pipes which helps improve exhaust flow, it keeps the engine bay a little cooler and the pipes do not rust out.
3 reasons for coated headers!!
