Help with 350/350th new crossmembers?

[LeftEar55]

OK, I need to know if I need to remove the old straight 6 crossmember and the old 3 speed crossmember? I'm pretty sure I need to remove the tranny one, but what about the engine one? If I remove it, where will the radiator mount back too??? Also, who should I get the new V8 and 350th crossmembers from? Does anyone sale bolt-ins or are they all weld in?

Not sure. You might post this one over on the Engine & Drivetrain section. I'll have these questions later myself. I'm doing all of the bodywork before working the drivetrain.

My father-in-law took the 216 out of his 1950 3100 and installed a chevy small block. He used the cross member from chevy duty without difficulty. I do not know if it was a bolt on or a weld on but I have found the folks at Chevy duty very open to questions. You can see theirs at http://www.chevyduty.com/frame-store.html

Thanks, I posted over in the engine forum, but answers yet!!! They're all whining about gas prices.

Save yourself time and overall $$$$ buy a new frame and suspension from RB Obsolete

Why would I do that? I don't need a new frame. I don't want coils in the front. I want to keep it mostly original, including the rough ride. What does buying a new frame have to do with my crossmember question anyway??? Also, looks like you are well off, by the list of cars your sig has. I, on the other hand, have very little money and can't just go out and buy useless stuff left and right. I have to save up for a part and hopefully can still pay bills afterwards...

Thank You, my wife has a newer car but I have had some of mine for 40years and am just getting around to finishing the last one, the 55.
If I had to do it over I would have started with a new frame instead of dollering one piece at a time as the funds came in. Yes I wanted those coil springs and better bracking and of corse more POWER.
Good Luck with your project

LeftEar55 If you decide to go with the cross members you are going to have the same problem I’m having. You don’t need to cut out the front cross member but you do need to cut out the trans one. But your block will sit real close to the steering gear box. About 1¼ inch. No room for exhaust. I’m thinking of using u-joint on the steering column to make it fit. But I have seen some trucks with the same setup with no u-joints, I just cant remember how they went about doing it.

WHYYYYYYYY?????? there's is NOTHING wrong w/the stock frame or suspension as long as it's in good shape(which most are), if a straight axel has been good enuff since the begining of time what wrong w/them now, remember they still use them under trucks .. as for brakes there are several companies that make disc brake kits that fit just about any type of car or truck out there, &&&&& they will stop anything they are put on, EVEN w/a BIG BLOCK w/a Blower & NOS on it. you just need the correct kit.

hey Jason BUILD it the way you want it, NOT they way others should think u should build it. i personally did a frame swap, WHY u may ask. well when u get half of a 1ton suspension & can't find or buy parts for it along w/the frame weighing 1000 lbs more then a 1/2ton frame, you do what you have to do. it was easier &&&& cheaper for me to do the swap then it was going to be to find & rebuild what i had......
like i said Jason BUILD it the way you want it done & forget about what others may say to you. cause they ain't paying the bills or driving it &&&& if ur happy thats all that matters. .....joe
