I have a '66 1/2 ton LWB with a 454. Does anybody know if headers for a later model will fit this ? The books don't list this being a big block wasn't available then.
Hi Rats.. You "may" be able to use headers up to 70 truck headers. Another thing that may work, with a little tweaking, are headers for " A " body cars with big blocks. A common practice with trucks from 60 66 with a small block is to move the motor mounts perches forward one bolt hole to provide clearance for an HEI at the firewall. I know of at least one case that the A body small block headers for the 350 worked fine. FYI : "A" Bodies are Chevelles 72 or earlier. The 72 Chevelle came with a big block so there should be plenty of choices of manufacturers like Hedman, etc,,, Dennis
Hey if you goive me a couple days i might be able to find some headers. right know i know of sanderson who makes headers(full lenght that should work but i might be able to find some more.i got mine from my unlce who got his from well i don't know exactly where he got them but the box they are in says Mr. Gasket. cowboy 1961 chevy 1/2 ton shortstep known as sarah(496 bbc coming sooner or later)
OK thanks Cowboy. Its going to be one of my winter projects in the garage. I know that the front suspension off the later trucks will bolt right up so I fugured the frame rails msut be bout the same. The guy I bought the truck from sure could have pushed the motor forward a couple inches. The way he had it mounted the valve covers and HEI were touching the firewal. Could have saved me some hammer swinging. So anyway thanks for any help.
are you going to move your engine forward? i would. and for the radiator what is it(are you) using? thanks cowboy 1961 chevy 1/2 ton shortstep known as sarah(496 bbc coming some day)
Na I'm not going to move it. At least not now. All I know its suppose to be a '79 motor and the guy didnt know what it came out of. Truck I think, and the radiator prob did too. I spent the first year re-doing things that he or someone had done. Let me know how those headers you bought work out.
[updated:LAST EDITED ON Oct-29-02 AT 00:16 AM (CST)]ok the headers i got are for a 67-87 chevy 396 - 454 big block. the paper in the box says that they are cyclone headers(the box says that they are from mr. gasket).So i think that they are made bye cyclone but sold by mr. gasket. I bought them second hand, but un used. so it is a good deal.i got them for 100$. they should fit fine. Can you get some photos of your radiator on the net so i can see how to do mine? Are your inner fenders cut? if so how much? i have a radiator that is out of a 79 chevy 1 ton that had a 454 and i was wondering how to modify the fenders. I found a radiator from brass works that is a 16" hex/octagon that might work good but i don't know how much it cost yet. thanks for the help cowboy 1961 chevy 1/2 ton shortstep know as sarah(496 bbc coming someday)
Sure thing. I have a site that has some pics of my truck when I first bought it. I'll get a couple pics of the radiator and take some dimensions. The guy I bought it from just had it kind of strapped in there. I'm working on a better mounting. The fenders aren't effected at all. Ill get that done tomorrow (Thurs). Have you got a big-block in it now or you working on it ?
I don't have the big block in it now but i want to put it in. i've got to get a new block the one i had was cracked. so i got to find a new one and get the parts. Right now i'm kinda pressed for funds so the big block will have to wait a while. I have the stock radiator in it now with a sbc (283) i was thinking about building a 350 that i have here but i would have to bore it and rebuild it. but i also want to put a big block in it. I haven't got any parts for the big block. Cowboy 1961 chevy 1/2 ton shortstep known as sarah(496 bbc coming some day or maybe a hoped up 350)
Wel, my digital cam just went haywire so I cant get any radiator pic rite now but the bigger should just drop in anyway. There's no mods done to mine. Iunderstand bout the motor having to wait. Just piecing my truck together as I can afford it. My site is jpstar3.tripod.com (dont use www)
