Has anyone out there put a predator headed RB engine in a stock engine bay?
I have a 63 dodge b body. Would there be enough room for the headers without
having to cut the fender wells????

Darren Tedder(DTHEMI) has one in an old B Body, believe it is a 65. Blasko has one in his Dart and Eddie Miller had one in a Duster. We had a 99 Hemi in a 68 Barracuda with inner fenders etc I see no reason a Predator cannot be done.

Yes in a B body they will work, there is not a production header for them but there is definitely enough room without cutting to make a custom set.

2 1/8" minimum tube diameter to start 2 1/4" is probably better suited.

In an A body... unless you are a contortionist there isn't room without cutting.

Would love to try a mild one of these in one of my cars....Love the valve train layout on them....

The valve train is bulletproof really..

Every rocker is the same and with pushrod oiling it is almost OEM like reliability.

Thanks for the info. Those heads would be cool to try. Its a toss up between the Indy -13 and the Predators. Anyone want to chime in pros or cons of which to pick???

All I will say is, look at the flow numbers and rocker geometry of the 600-13's VS the Predators. I had some B1/MC heads on a 572 engine I had. The combo was a 16.3-1 comp., .890 I .810 E, 112 LC Duration 288-298@50*, maxed out at a true 449 I flow on a 4.500 fixture. It ran 7.50's and 60's at 172-174 MPH in 4500 actual elevation but commonly 5500-8500 Corrected and easy to tune converter and 60' wise.
My Predator headed 572 using the same block, crank, etc. had a like cam, 14.5-1 comp. In the same air, and once I started to get the combo and converter figured out (much looser) it ran mid 50's and high 40's at 175-177 MPH. I am sure many here will dispute this but, the predator stuff makes more power and is better that the B1/MC stuff. IMO and I've never done an Indy 600-13 headed engine, is the B1/MC head is better than the 600-13 based on the N/A engines I've seen running them.
The wedge head is easier to tune though as there aren't many here that know how to tune the Predator deal, so there is more trial and error. Al Alguire, Boat racer (Tony), and I am sure a few others here can help. Indy was absolutely the worst and always has been, customer service I have come across. At least with the B1 stuff there are people to ask, and Scott Koffel can give advice and does.
I would never go back to a wedge head on a Mopar though. Also, don't believe the Indy garb about 1350HP N/A. JMO

I have a couple predator motors, and workinh on a third. One in a 66 B body with factory inner fenders, and factory offset. There is more than enough room, but like someone else said custom headers. The 66 is iron block, and 3400 w driver. Runs 5.28 in the 1/8th on a single 4 na. I don't think there's a better mopar head out there save exotic stuff.

i think the "new" 600-13 will give em a run for there money...maybe even equal or better.the only plus is the pred still uses std bore spacing block.

If it was just about flow, than maybe the 600-13 would have some chance with the Predator.

It isn't just about flow.

yes i know .....i know of couple guys making some serious steam with those heads with track times to prove.so its not just about flow....

It doesn't help that the 4.800 crankshaft has to offset rods to piston pins to fit a 4.840 block either. At least that's the way I understand it. And the only head and block that work with that combo is the 600-13 and 4.840 Indy......well I'll be nice and say stuff.

i never realized it got even more complex not just the exclusive block deal.....pred looks like the smarter bet.

BAE for the win

If BAE made water stuff...

Head gasket reliability being a symmetrical port design helps on the predators too.

That was the main reason I went that way.

BAE will make u anything you want,( forged semi water block) but your going to pay$$$$$ for it

NRE(Noonan)just came out with a billet hemi water block and head combo at PRI.

A little off topic here but do any of you guys that build predator head engines have a used set to suit a wedge block for sale ?

Very tough to find used, once people run them they very seldom come off there motors in usable comdition... easier to find then new/bare
