Main Bearing supports
Hey Propwash. I will definitely be using the stud package at a minimum. The jury is still out on the main bearing saddle and billet steel caps. I just haven't decided 100% for sure.
I'm going to get the 500 inch Stroker kit from 440 source. I don't want to go any bigger than that for several reasons. First off is the rod / pickup tube clearance with the larger stroke. I wanted to keep a stock internal oil pickup, but may end up opening it up from 3/8" to 1/2". If this car was going to be seriously raced then by all means it would get an external pickup for sure. My goal is to keep it looking "kind of" stock, sort of like a "Day 2" car with different things like headers, intake and valve covers.
In the beginning of this thread I posted up some pictures of a 1970 plum crazy Challenger R/T that I built for a friend about 6 years ago. His car has a stroked 440 (500 cubic inches) in it that was built by Herb McCandless. The Challenger is a real Beast. The torque from that car in unreal.
Herb told my friend that it wasn't good to go "Too Big" with the stroke and try to keep it around 500 inches or so. His reasoning behind that was he had a row of RB engines siting in his shop that had cracked blocks near the mains. He even sent us a few pictures that showed some cracks that went external above the oil pan rails.
Now I don't know how hard these engines were ran, or even how long they held up, but I try to learn from others mistakes. But this engine for the Challenger was built back in the early '90s when Indy heads were just coming available. I don't know if the main girdles were readily available then.
This thread has changed quite a bit from when I first started it. The "Stroker" engine I'm building now will go in the 72 Satellite Sebring. Its going to be my "Have Fun" car.
I am still holding on to the date code correct 440 for my 71 Road Runner that this thread was started about.
I have a new set of 440 Source "Stealth" aluminum heads that I originally bought for the 71 RR. Now it looks like they will get installed on the Stroker engine. I've been thinking about doing some mild pocket work on the ports, gasket matching the port openings, upgrading the valve springs and retainers, then CC'ing them before they are bolted on.

Thanks again Photon. Do you have any experience with RB Strokers ????

Here are a few more pictures of the Challenger during it's assembly. I ended up re routing the fuel line braided plumbing and swapped out the cast Indy valve covers for a set of MP ones.
The skinnies are not on the front any more. They were just to roll the car in / out of the shop. It has a Milodon pan with external lines and swinging pickup. TTI 3 inch exhaust, Dual Disc clutch with a Lakewood housing,
and a 6 speed manual trans!!!!
Back when we started this project in the early '90s, we were the 1st people in the US to get a 6 speed gear box for a Mopar. We had to fabricate EVERYTHING !!!!
Now its available in a kit from several sources...............

My next door neighbor is a pin stripe / air brush artist. I asked him to take the original font and style from a 440 "Six Pack" air cleaner decal and make up something cool that would be a little sneaky too......
Notice it says "500 Indy STROKER" and incorporates the INDY logo with the "valve" as a letter "Y".
I cant tell you how many times people have walked past the car looking it over and as they walk away the air cleaner hits them. Then they come back and look at it again............
I think my neighbor nailed it pretty good. Its all free hand and air brushed. I cleared over it when the art work was done.

The last time I did any machine work on any engine was also back in the early '90s. A lot has happened / changed since then and the aftermarket parts industry has really come a long way.
So seriously, if any of you have any experience with the 500 inch Stroker's I'd love to hear from you.
Please fell free to chime in like Photon did. I would really appreciate that. There is a wealth of knowledge here on FBBO.
Thanks.
