C1 fuel injection RH exhaust manifold

[Keith R.]

Sorry to beat a dead horse all, but have searched the forum and archives a number of different ways to find out the correct casting number for a C1 fuel injection right hand manifold. Can anyone in the group verify the right number? Thanks.

B52 Pile it... If you would give the year and if you had an NCRS spec guide or an NCRS Judging Guide, you could answer that question yourself...

Re: C1 fuel injection RH exhaust manifold

Thanks Dennis. I've read the JM guidance a number of times and I don't think that it reads clearly. It says, "3749965 - Left-Hand; 3750556 - Right Hand; and, 3732498 Right-hand ('58 FI possible)" So specifically, my question is, which casting number is correct for a 1960 FI right hand exhaust manifold, 3750556 or 3732498?

According to the NCRS Spec Guide - Right Hand:

The '498 = Early 1958 FI (possible)
The '556 = All Engines

Of course, choke hole drilling/non drilling on FI must be considered as part of the package.

Best, Dennis

Re: C1 fuel injection RH exhaust manifold

Thanks mucho Dennis - '556 it is then. Still don't quite understand what year the '498s are found on other than 1958 FIs possibly.

Best,

Yeah Keith, I'd head for a non drilled '556 (FI application) and be a happy camper. Of course, unless you are one lucky dude and have one in your possesion, finding an original is a tough, expensive nut to crack. I believe a pretty good one may be available in reproduction, but I would advise you have your hands on one before you lay down your frogskins...

I'm sure if you can fly a B52, you can read between the lines...

Re: C1 fuel injection RH exhaust manifold

check out the junkyards for chevy trucks of the 57-60 variety. need to be a 1 1/2 ton or more critter to get the non-drillled for choke right hand 57 fi manifold. figure on about 500 frogs for an original unless your junkyard trip is successful.. the repo's are discernaby different than the originals.mike
