Thread: Project $ 3 K Is Underway

I didn't know anybody was currently making the chambered exhaust like the old Camaro ones. Really compact and short too. Thanks Bob, I've bookmarked that site and will pass it along to him.

How different do you guys think those will sound from a glass pack/cherry bomb?
I have one of the cherry bombs on the truck now and it appears to be the same design inside ,...with no glass,but it does not have the chambers crimped in it..............
Now that my engine is broke in,I want to add nice stainless headers and true duals,but room is a issue,these would be nice in my application also.

I think chambered exhaust sounds a lot better than a glass pack. They can be loud, but in a good way. I have them on my '40 and absolutely love them. A buddy had them on his '57 Nomad and while they sounded great, they were pretty loud and he finally swapped them out. It seems like a lot of the sound will be determined by the engine and size/length/run of the exhaust.

When my buddy who owned a muffler shop was putting exhaust on my '40 the first combo he tried was a set of Flow Masters with 2.5" pipe. That sucker had a drone at certain speeds that would drive you nuts. He tried several different set-ups and finally found the right combo with the chambered and slightly smaller pipes. The difference was incredible, even in the power the car gained with the chambered.

Don and I spent most of last night trying to sort out the misaligned pulley setup. Who would ever have thought that such a simple thing as pulleys would turn into such an ordeal??

For any of you going the same route (small block Ford V belt setup) here is what we have learned.

First of all the engine is a 1985 roller cam engine that had serpentine belts originally. We wanted V belts because they look less modern. Don ordered a Chrome Summit water pump and March V belt pulleys. Got the water pump on, and when we installed the pulleys on the crank and water pump they were about one inch from being in alignment. Spent 4 hours on the phone with Summit, March, FlowKooler, and Edelbrock yesterday and finally determined we needed a Flowcooler pump for early '70's 302, and a 15/16 thick spacer from March for the crank shaft. Had those parts airfrieghted in.

Last night got them on, and the alignment is now ok. Went to put the alternator on, and it sits back too far by about 1.5 inches !! Called Summit last night, they don't have a clue. Today I spent 3 more hours on the phone with March and Summit, and come to find out March makes the pulleys but designed them around stock Ford alternator mounts, which we do not have. March does not make an alternator mount for that application.

Got back onto Summits website and found a set of Ford Racing pulleys that will bring the belt back far enough to use the alternator mount March does make, so those two pieces are coming overnight and should be here tomorrow. Hope they are correct. Right now we have about $ 800 worth of pulleys, water pumps and alternator mounts sitting on the floor that won't work, so Summit is going to be getting these back as soon as we determine the new stuff works.

I also found out the Tech line at most of these companies are useless, they just work from the catalog or website, and I can do that. I really needed a Ford small block expert to say what parts went with what parts.

By the way, Dan is still remodeling his A, the grille needs chopped and the back rails cut to fit, but it is looking good so far IMO.
