1947plymouthrodder Posted September 23, 2015 Report Share Posted September 23, 2015 Hello, Been awhile since I posted. Starting to get back into my 47 plymouth project and had a couple questions. Doing the cavalier R/P install, what oil pans have people used to ensure clearance for a BB mopar (413)? I have a front and center sump available, but both look like they won't work with the R/P. For the rear, I am looking to get rid of the leaf springs and install a 4 link with either coilovers or airride. What kits are people using? The rear end is a 323 sure grip out of a 69 road runner. Any info or experience people have would be fantastic. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
Mark Haymond Posted September 23, 2015 Report Share Posted September 23, 2015 On a Mopar 318 engine conversion for my 47 Plymouth I used a rear sump oil pan from a truck or van to clear the Cavilier r/p. Be sure to get the correct dip stick to go with it. I am using leaf springs on the rear so I do not know anything about trying to mod a four link "kit" to work in the rear.

wayfarer Posted September 23, 2015 Report Share Posted September 23, 2015 Rear sump pans are available for the B&RB. If you 'think' that a 4-link is superior to leafs on a street car then consider all of the R&D that MaMopar put into leaf systems for all of the muscle cars as well as the SuperStock drag cars in the 60's and 70's. If you want a 4-link because you think they add some 'cool' factor then go for it. IMHO, Mopar leaf systems are the way to go for a combined package of ride quality, traction control, cost and ease of installation. 1 Quote Link to comment Share on other sites More sharing options...
Frank Elder Posted September 23, 2015 Report Share Posted September 23, 2015 look up Watts link with a rear sway bar and the proper leaf system. Quote Link to comment Share on other sites More sharing options...
1947plymouthrodder Posted September 26, 2015 Author Report Share Posted September 26, 2015 Anyone have any pics of how they did their motor mounts? Had a set made up but i am scrapping them due to some miscalculations :/ It's a big block wedge in a 47 plymouth. I have a couple ideas, but just looking for some pics and experience. Thanks!

1947plymouthrodder Posted September 26, 2015 Author Report Share Posted September 26, 2015 Thanks guys, I have a lead on a big block oil pan so hopefully that pans out (no pun intended ) As for the rear, I understand the leaf springs are more than capable, But I am looking to add airride, and it won't work with the leaf springs. Thank you for your input Quote Link to comment Share on other sites More sharing options...

Sharps40 Posted September 27, 2015 Report Share Posted September 27, 2015 Doing suspension on my 37 dodge. Builder asked if I planned for passengers. I said yes. He said no 4 link then. Stick with elliptical springs for best ride. Quote Link to comment Share on other sites More sharing options...
falconvan Posted September 27, 2015 Report Share Posted September 27, 2015 I had to use a rear sump truck oil pan for my big block in my 49. The pan wasn't too hard to come by but the oil pump pickup is another story. You need a specific one for the rear sump pan and it's out of production. I ended up having to make one using a Milodon pickup by shortening it and building a different mounting bracket for it. 2 Quote Link to comment Share on other sites More sharing options...

He said to keep the leaf springs out back if you actually plan to put people in the vehicle and drive it a lot. Better ride by far in his experience.
