i found a great looking 429 in my buddys dads basement with DOVE-C on the heads DOVE on the manifold and i couldn't find one on the block but it was dark. it has a breaker ignition on it and the valve covers say powered by ford. my question is how do i tell what output it is? whether its a TJ or CJ OR SCJ OR what? i plan on sticking it in my E-250 ChateauTrailer special for cruisin around camping pulling my boat and playin around etc... i have a Good C6 with a B&M kit.

 

It's a thunderjet. CJ/SCJ's had D0OE-R heads. Boss's have hemi heads with plugs going down through the middle of the valve cover.

 

so what kind of power are we lookin at out of that motor?

 

360 hp and torque around 500, but I can't remember off the top of my head.

 

Wow, I have a D0VE-A Block with D0VE-C Heads, and powered by ford on the valve covers, is this what I have to? holy toledo thats a lot of torque, mine isnt running yet, but your gettin me excited now.....

 

Compression on those is probably a bit too high for today's gas. I don't know of anyone who is running a stock thunderjet anymore. You'd likely have to mix your gas or rebuild with a slightly lower CR.

 

I have got one that is all stock except for a very small crane powermax and I pull a sled in our stock pulling class on 92 cotane . I believe that the 600 holley necks down the dynamic compression so bad that it will work.

I am.
Nothing fancy yet.

The 2V (320 hp) gives more torque for pulling, but the 4V (360 hp) gives more top end.

 

I am running 10.5:1 static CR and I can run regular gas in the winter but I need 90 octane in the summer. No premium.

I run Keith Black pistons (KB138) that I set up 0.030 quench (deck height 0.00) and smoothed (not polished) combustion chambers and pistion domes, to prevent hot spots. D0VE heads. I run a cam with a slightly more overlap that stock to dynamically bleed off some of the compresssion.

In the prepping of my baby for its maiden voyage, I have seen so many topics on thunderjet compression and drivability on pump gas. And I think it all started with my realization of it in this thread. And after reading all these topics, a few started by myself, I am planning on a cam and some premium fuel to see what happens, Dennis is doing it, as are others, It may very well depend greatly on fuel quality where you live, altitude, and a bunch of other factors.

If the premium gas and Cam with some overlap dont work, head work is next, I am determined to get this thing to run like it used to in its heyday.
