I am installing a Fenton exhaust system on my GMC 228, and have run into the classic throttle linkage issue (going to the stock singe carb). Has anyone worked with a throttle lever as shown in the picture here? I'm assuming I'd just bend the current lever to towards the engine and make up a new connecting rod to the carburetor, but if anyone has any experience or better ideas than that, please share!
If anyone cares to know, I am switching to Fentons because my stock exhaust was basically fused together and ruined by rust and heat, etc. It would take some serious welding and fabrication to bring it back to life. The old pipes (which were literally housing plumbing) were also hung with... coat hangers? Lord only knows what they might have scrapped together on our old farm... So, hence the need for a new exhaust system.
Also, do these pipes look correct coming off the headers so far? The guys at the parts store said that's how they're supposed to go, but they just look like there are too many parts compared to others I've seen.
Any good muffler shop can fab your dual pipes, should have plenty of room under there. I ran dual down the left side, looks and sounds good. Re the linkage, I used 'heim' joints for smoother pedal. Best of luck
Those look like they'd be an improvement! I need to get that linkage on the block figured out first. It just makes me sweat to bend a hard to find, original part... Didn't know if anyone on here had a part number or something that worked for them, or just custom made everything.
I bought some round stock iron and bent up my own rod from the bell crank to the carb. I took a while and some tinkering to get it right where it wont bind, but its doable.
It is very doable , there are lots of us with fentons and standard intake , it just takes a bit of time , maybe a few attempts at the bends , but it does work . Additionally , I encourage you to exhaust heat the manifold , I tried both water heat and exhaust , the latter has been better , more like the factory assist.
Good to know. I'm sure we'll make something work. The technical term I finally found for this part is "bell crank." It seems every engine has a slightly different bell crank between the throttle and the carb, so it's just a matter of creativity, like you guys are saying.
And yes, we've got the kit from Jim Carter. Seems like it should button up to it just fine.

I use water to heat my Offy manifold (not standard). I had it both ways also and the Offy was showing signs with exhaust heat. Switched back to water. No problems since'
