Home Forums Hunting & Shooting Hunter's Campfire 1969 Roadrunner revival

Actually I think we got a little confused with the idea that I might be looking for headers, but I'm not.

Tzone was showing some headers his dad got for the FE in his 64 ford... er, merc that is.

I'm perfectly happy for the time being with the HP cast manifolds on my 383. I'm not looking for headers right now, the HP manifolds flow pretty damn good and I've got 2.5" aluminized pipes out the back, flowmasters and a crossover tube.

It works just fine for my needs right now.

If I Get to hunting for hard to find 2 or 3 HP here & there I could eventually go after the headers but I like the HP manifolds.

Grouseman, I'm impressed to hear you mention the extrude hone process though. Here I thought it was just a flash in the pan blip on the radar from a couple decades ago.... good to hear people are still using the process.

As far as mopar traction, your most common reply is going to be pinion snubber and or possibly a spring change.

Second most common suggestion might be a set of cal-tracs.

If you can lay hands on the old style cast , Mopar headers Dave.Snatch 'em up.
Everybody back in the day took 'em off for tube headers that rusted away.
And gained only a couple HP at best. Chrysler was ALWAYS the best at flow design. I worked for an Chrysler engineer that went on to design the open chamber SBC head. Also the Mopar Indy engine.
He was an engine flow Geenius!

I'm running those manifolds right now.

my engine in stock form is rated at 335HP, mine is mostly stock with exception to the cam.

I can jump it to around 450HP with about 4 common bolt on performance components. (about $1200-$1500)

But I'm in no hurry, i just want a nice looking driver for now.

Yea, Cal-vert is the common upgrade if Superstock ( SS) springs don't fix traction issues on a leaf Mopar, so I hear.


And I believe the 335hp was conservative due to insurance reasons from 68-72ish, I suspect a cam and better carb would net you an easy 400 hp, but you still, IMHO need 3.55 or 3.73 gears with the 4 speed....

It is coming along nice Dave. Can't wait for the car show.

It will be pretty amazing if I can have it ready in time for our show.

I'm going to try, it's not really likely tho





RH wheel house.

Guess I should explain, that's not an overlay, that's a butt weld fit.

I see a problem Dave...........

do tell?

The problem is Dave does a butt weld different than you do???

R.

Oh just before I posted that I noticed my coffee cup was empty....nothing on your end.

I just new "butt weld" wasn't safe lingo here.

oh, and on the topic of the pinion snubber plate, i damn sure gots one.

I just need an adjustable pinion snubber to reach high enough to contact the plate.

Thats how I do my butt welds too.

Fab one.

At least you didn't say it was a full penetration butt weld, with chamfered edges.

R.

Thats not what Ingwe says....

R.

He's not supposed to tell.....

I know. The whole don't ask, don't tell thing...

R.

Yep.
