Not sure if this is the correct place for this question, but I couldn't find any thing like it any where.
I'm looking on e-bay for the exhaust manifold to dump at the back of the engine, and the only ones are specified for late 60's, early 70's. Will it still fit on the 1980 440-3 motorhome engine? Might as well go with the HP while I'm looking. Just wanted to make sure it all stayed the same all those years. I want to drop this in the 71 charger. I have a decent cam to put in it, and from what I have found out, I just need to port the heads for this engine to to handle high RPM's.

Uhhh! Today I Googled some more an came across a forum where they were saying using passenger heads on a motor home block would cause overheating problems. If I had any motor home parts I would start poking around the water jacket in the blockwith a wire coat hanger to determine where the difference is. Same with the heads. I thought it was funny because I had a 440 in my 1964 Plymouth with a 3 row hemi radiator and its would overheat in traffic.
440 exhaust manifold swap, 70 to 80?
