New to the V8 Buick site and need to get up to speed quickly. I've been a Pontiac guy for 30 years but recently picked up a VERY clean and original 72 Skylark... w/o a motor. Since I don't have the numbers matching engine and have access to a tight, low mileage 430 I thought why not drop it in the Skylark. This motor has a center sump oil pan, I need help locating a rear sump pan and 5/8" pick up tube. I have the correct cast iron frame mounts. I'm also looking for info and advice on making this transplant. Will the 430 exhaust manifolds work? Is there anything else I might need? Has anyone else done this and if so how do you like the 430 engine vs a 455?
