60 NY er fit ---what we did , removed heat riser valve “throttle “ plate , it cannot work at all anyway with no side to side crossover passages under carb when you have rams; not driving rams in 2016 when cold out , so did that on both sides , long discussions about that in past posts ; original vs non issues. I resist any more on that! So no heat riser comes with that NY er answer. And I think it is OK. If driven in temperate climes. Stuck stock ram heat riser (not uncommon, stick so as to send all exhaust though the elbow(cold position) destroys rams, overheats aluminum floor of carb chamber . melts a hole in it.
We got 60 NY er generator manifold I think from a good guy club member, he had parted out a NYer 413, reasonable price. been getting lots of parts coming and going, becomes blurred . Murray Park had one for about 250, a lot yes, but try and find a 60 ny’ er manifold. Others might fit from 60 rb blocks ,. Maybe even B , maybe 59. But I do not know about 59.
Hope that helps….
Aside from the heat riser ports, how different are the these manifolds from similar ones without the ports (eg for single 4 bbl engines)? How critical is the heat riser?
Yes, they are different, they have separate exhaust passages to heat the chokes. The 300F right side is even a bit different than the 300G right side because of the generator mounting in the F vs the alternator mounting in the G. There are companies that specialize in repairing exhaust manifolds, I would consider seeking one out and discuss the specific problem with yours to see if they could repair it. It is a very specialized repair and must be done by someone that really knows what they are doing, and even then there typically are no guarantees. Also look on eBay as they do come up from time to time, usually in sets. Perhaps a club member will have one they can part with. Fortunately, cracking is not a common problem with ram car exhaust manifolds.
Hi all - are the exhaust manifolds on the cross ram engine different than the other 1960 413's? The right one is cracked and my mechanic does not recommend trying to weld this one. If different, can anyone recommend a source?
