[gene mac]

I have done a couple. They are fun! No cage necessary but frame connectors are recommended.

Start with visiting the bigblockdart tech pages. Most of the answers to your questions are there.

thanks dave i appreciate the input the frame is tied i have the 6 cyl. k member an torsion bars do they pose any handling issues on the street?

 

[d55dave]

Depends on what you want to do with the car. Old scho drag racers prefferred the 6cyl bars as they allow the front suspension to unload faster on launch. Most people nowadays seem to put in bigger bars for handling. Remeber that they are fully adjustable, you can set the ride height wherever you want.....

As for the k frame, no difference as long as you have proper mounts. Looms like the big blocm is already in there!

There's quite a few on here.

Before suggesting headers, it would be better for you to tell us what trans you're planning to run.

Cage isn't necessary for the street, but if you're planning any track time, it's not a bad idea.

Slant 6 bars are good, but a little thicker, maybe 318 A/C bars or bigger, could improve handling.

I'd suggest checking out some members builds to get ideas.

Good luck with your build.

Frame supports mandatory. I also supported firewall to fender wells as well. Used 1" square tubing across fender wells to core support.
Then to firewall. Only cause I cracked windshield after some launches.
Mainly because of 2 1/8 fender well headers. I presume.

In that case, I'd suggest chassis headers, unless the car is being built for strip only and then I'd go with fenderwell headers.

 

[d55dave]

Fenderwell headers are just plain cool....... IMO. My last bb dart had them and yes, remove the minimum amount of fenderwell possible and some extra chassis stiffening is good........ if you want fenderwells. If it is a mild build you can do the c body manifold thing.

Schumacher headers fit great and I have had my car down to 11.30s with them. Frameties are needed.

 

[gene mac]

thanks 68 dodge frame is tied

Radiator I used is from Be-Cool and it sits on the frame rails with daul electric fans and water pump

has anyone pulled this off ? what radiator headers did you use an any issuse youve run across with them

easy swap these days...

conversion mounts readily available
multiple headers available these days
tons of radiators out there these days that will work..

back when i did mine tti weren't around yet so i went with the pro parts headers.. really nice header but partial fenderwell.. today depending on my build i'd schumacher or tti.

mounts i'd just go schumacher for whatever k-frame i have. yes transdapt sell for half the price but after using transdapt for my small block they are half th equality as schumacher too..

when i did my big block years ago i just used a recored small block 22" radiator.. they put a stagard core in it.. worked well.. now there are tons of aftermarket radiators out there that will work..

all in all its a bolt in swap.

 

[abodyjoe]

the demon (purple engine bay) is the one with pro parts headers.. the other is a 64 valiant. custom mounts and headers..

 

[mycuda]

If you're into performance exhaust manifolds aren't the answer.
But if it's a car that's worth saving and not destroying Fender Wells that's a different story.

I had a 440 in mine.Tight fit.

Do yourself a favor and use an offset master cylinder plate.

is it because of a heat issue or a clerance issue mine clears valve covers fine
